00:00At 0530 on December 17, 1944,
00:04Lieutenant Colonel David Pergren stood in the frozen command post at Malmödie, Belgium,
00:09watching radio operators track a mechanized column
00:11that had just broken through the American front line, 8 miles east.
00:1526 years old, 8 months commanding the 291st Engineer Combat Battalion,
00:21zero experience stopping a panzer spearhead,
00:24the Germans had unleashed Kampfgruppe Piper, 5,000 Waffen-SS soldiers,
00:30117 tanks, including 45 Tiger IIs, Joachim Piper commanding.
00:35Their mission was simple, punch through to Antwerp, cut the Allied armies in half, win the war.
00:42Pergren commanded 600 combat engineers, not infantry, not tankers, engineers,
00:47men trained to build bridges and clear mines.
00:50They carried rifles and grenades, but their primary weapons were C-4 explosives,
00:55detonator wire, and technical knowledge.
00:57The German breakthrough had caught 1st Army completely off guard.
01:01Infantry divisions were retreating in chaos.
01:04Armored units were scrambling to regroup.
01:06Nobody was in position to stop Piper, except Pergren and his engineers.
01:11The math was brutal.
01:121st Army had lost 2,300 men in the first six hours of the German offensive.
01:17The 99th Infantry Division was being torn apart at Elsenborn Ridge.
01:21The 106th Infantry Division had ceased to exist as a fighting force.
01:26Entire battalions were surrendering or fleeing west.
01:29The roads were clogged with retreating Americans trying to escape the panzer columns.
01:33Pergren received his orders at 0615, establish roadblocks south and east of Malmedy, defend the town, delay Kampfgruppe Piper.
01:43No reinforcements available, no heavy weapons, no tanks, just 600 engineers with small arms and whatever explosives they could gather.
01:51The German advance was moving faster than anyone predicted.
01:55Piper had already captured Hansfeld at dawn, taken fuel from American depots, captured vehicles and weapons.
02:02His lead elements were racing west along narrow forest roads toward three critical bridges.
02:08Abimont, Trois-Ponts, Neuf-Moulins.
02:11If Piper secured those crossings, his tigers would break into open country.
02:17Nothing between him and the Meuse River.
02:19Nothing between the Meuse and Antwerp.
02:23Pergren studied the map.
02:24The terrain was his only advantage.
02:26The Ardennes was heavily forested.
02:28Steep hills, narrow roads, rivers cutting through valleys.
02:32The Germans needed bridges.
02:34Every bridge.
02:36If the bridges were intact, Piper would race through.
02:39If the bridges were destroyed, his entire Kampfgruppe would stall.
02:44Pergren made his decision.
02:45They would blow every bridge before the Germans reached it.
02:48Not after the Panzers arrived.
02:50Not during a firefight.
02:52Before.
02:53They would watch for the German columns, calculate timing, wire the charges, wait until the last possible moment, then destroy
03:01the crossing.
03:02It was a suicide mission.
03:04Engineers working under fire were easy targets.
03:06Exposed on bridges.
03:08Visible to German gunners.
03:10One mistake in timing, and the Panzers would capture the bridge intact.
03:14One moment of hesitation, and the engineers would be overrun.
03:18The detonation teams would be standing on the bridges when five-ton Tigers rolled into view.
03:24Other officers questioned the plan.
03:26Some called it reckless.
03:28Others suggested falling back to defensive positions farther west.
03:31Let the infantry handle Piper.
03:33Let the armored divisions counterattack.
03:36Engineers were not supposed to fight mechanized SS columns.
03:40Engineers were supposed to support infantry operations.
03:43Build bridges.
03:44Not blow them up in the face of advancing Tigers.
03:47Pergren ignored the criticism.
03:49His battalion had trained for bridge demolition.
03:51They knew explosives.
03:53They understood structural weaknesses.
03:55They could calculate exactly where to place charges to drop a span.
03:59The question was whether they had the nerve to stand their ground while German tanks approached.

04:13Back to Pergren.
04:14The first test would come at Habemont.
04:16A small stone bridge over the Amblev River.
04:20C Company had the assignment.
04:21Lieutenant Bucky Walters commanding.
04:2323 men.
04:25Enough C-4 to collapse the span.
04:27Radio contact with forward observation posts watching for German movement.
04:32Walters positioned his demo team on the bridge at 0700.
04:35Wired the charges to the stone supports.
04:37Connected the detonators.
04:39Ran the wire back to a covered position 50 yards west.
04:42Then waited.
04:43German reconnaissance vehicles appeared on the east bank at 0742.
04:48Half tracks.
04:49Scout cars.
04:50Moving fast.
04:51The lead elements of Kampfgruppe Piper.
04:53Behind them, the first Tigers.
04:55Walters watched through binoculars.
04:58Counted vehicles.
04:59Estimated distance.
05:00His hand on the detonator.
05:02The Germans were 400 yards away.
05:04Then 300.
05:05Then 200.
05:06His men were asking if they should blow it now.
05:09Walters kept waiting.
05:11150 yards.
05:12100.
05:13The lead vehicle reaching the bridge approach.
05:16And Walters still had not triggered the charges.
05:18The lead German half-track reached the western edge of the Habemont Bridge.
05:22Walters could see the driver's face.
05:24See the SS markings on the vehicle.
05:27See the machine gunner swiveling his weapon toward the American position.
05:31Walters squeezed the detonator handle.
05:33The explosion lifted the center span six feet into the air.
05:36Stone blocks weighing half a ton flew in every direction.
05:40The lead half-track tried to break, but momentum carried it forward.
05:44The vehicle dropped into the gap where the bridge had been.
05:47Crashed into the river 20 feet below.
05:49The second vehicle stopped, backed up.
05:52German soldiers jumped out and began firing across the river at the American position.
05:57Walters pulled his men back.
05:58They had accomplished the mission.
06:00Habemont Bridge was gone.
06:02Kampfgruppe Piper would have to find another route.
06:05The demolition had bought 1st Army perhaps 30 minutes,
06:08maybe an hour if the Germans had to reconnoiter alternate crossings.
06:12Every minute mattered.
06:14Every delay gave American forces more time to establish defensive positions.
06:19But Piper was not stopping.
06:21His column turned south, headed for the bridge at Trois-Ponts.
06:25A larger crossing.
06:27Two bridges, actually.
06:28One over the Ambleve.
06:30One over the Somme.
06:32Both bridges were critical.
06:34If Piper captured them intact, he would have a direct route to the Meuse.
06:38The town of Trois-Ponts was defended by a single squad of engineers.
06:42Twelve men.
06:44No heavy weapons.
06:45No anti-tank guns.
06:47Just rifles and whatever explosives they had managed to gather.
06:51Pergrin knew the Trois-Ponts situation was desperate.
06:54He radioed the squad leader, Sergeant Robert Billington.
06:58Told him to prepare both bridges for demolition.
07:01Wire every support.
07:03Use every pound of available C4.
07:05Blow both spans the moment German lead elements appeared.
07:10Do not wait for orders.
07:11Do not hesitate.
07:13Destroy those bridges.
07:15Billington began work at 0830.
07:18His men placed charges on the Ambleve bridge first.
07:21The structure was steel and concrete.
07:23Newer construction.
07:25Harder to drop than the stone bridge at Habimau.
07:27They positioned explosive packs at critical load points, main supports, joint connections, areas where structural stress was concentrated.
07:37Used twice the normal amount of C4 because they had no time to calculate precise charge placement.
07:43The Somme bridge required different tactics.
07:46Older construction.
07:47Stone arches.
07:49They drilled holes in the keystone positions.
07:51Packed the cavities with explosives.
07:54Ran detonator cord between the charges so one trigger would blow the entire sequence.
07:59Both bridges were ready by 0915.
08:01Billington positioned his men in buildings overlooking the crossing.
08:05Told them to hold fire until the bridges were down.
08:08Then, get out.
08:10Do not try to defend the town.
08:13Just blow the bridges and run.
08:15German tanks appeared on the eastern approach at 0938.
08:19Tigers.
08:20Four of them.
08:21Moving in column.
08:22Behind them came half-tracks carrying SS Panzergrenadiers.
08:27Billington waited until the lead Tiger was 30 yards from the bridge.
08:31Then triggered the Amblev demolition.
08:33The blast was enormous.
08:35Much larger than the Habimau explosion.
08:37The entire center section of the bridge disintegrated.
08:41Chunks of concrete the size of automobiles crashed into the river.
08:44The Tiger stopped.
08:46Piper himself was reportedly in that lead vehicle.
08:49He climbed out.
08:50Stood at the edge of the destroyed bridge.
08:53Stared across the gap at the American position on the far bank.
08:56Then, Piper did something unexpected.
08:59He began laughing.
09:00Not angry.
09:01Not frustrated.
09:02Laughing.
09:03His officers gathered around him.
09:06Piper pointed at the demolished bridge.
09:08Pointed at the small group of engineers retreating through Trois-Ponts.
09:11Then he said the words that would become famous throughout the 6th Panzer Army.
09:15Those damned engineers.
09:17Those damned engineers.
09:19The phrase spread through the German ranks within hours.
09:23Piper radioed it to division headquarters.
09:25Other commanders picked it up.
09:27By nightfall, every SS officer in the Ardennes offensive knew about the American engineers
09:32who kept blowing bridges.
09:34The engineers who were not supposed to be combat troops.
09:37The engineers who were delaying the entire northern thrust of Hitler's last offensive.
09:41But Piper was not finished.
09:43He ordered his column to turn south again.
09:46Find another bridge.
09:47Another crossing.
09:49Somewhere the Americans had not had time to wire demolitions.
09:52His intelligence officers studied maps.
09:55Identified a third option.
09:56A smaller bridge at Neuf-Moulin.
09:58Less than three miles from Trois-Ponts.
10:00Probably undefended.
10:02Probably intact.
10:04Pergrin received word of Piper's movement at 10 hundred hours.
10:07The German column was racing toward Neuf-Moulin.
10:10B Company had one platoon in that sector.
10:13Lieutenant John Kirkpatrick commanding.
10:15Nineteen men.
10:17They had explosives.
10:18They had detonators.
10:19But they did not have the Neuf-Moulin bridge wired.
10:22Not yet.
10:23Kirkpatrick radioed that he needed at least 45 minutes to place charges and run wire.
10:28Piper would arrive in 30 minutes.
10:30Maybe less.
10:31Pergrin made the calculation.
10:3345 minutes of work.
10:3430 minutes until German arrival.
10:36The math did not work.
10:38Kirkpatrick would still be on that bridge setting charges when the first Tiger rolled into view.
10:43Pergrin told Kirkpatrick to do it anyway.
10:45Get on that bridge.
10:46Wire the charges as fast as possible.
10:48If the Germans arrived before the work was complete, blow whatever was ready.
10:53A partially demolished bridge was better than an intact crossing.
10:58Even damage to the approach ramps would slow Piper down.
11:01Buy more time.
11:03Every minute counted.
11:05Kirkpatrick and his 19 engineers reached Neuf-Moulin at 10.15.
11:09The bridge was a simple steel truss span over the Lien Creek.
11:13Narrower than the crossings at Abiemont and Trois-Ponts, but still capable of supporting Tiger tanks.
11:19They unloaded C4 from their truck, grabbed wire spools, ran onto the bridge, and started working.
11:26The demolition required precision even under time pressure.
11:30Bridge trusses were complex structures.
11:32Blow the wrong members and the span might stay up.
11:35Waste explosives on non-critical points and the bridge would sag but remain passable.
11:40Kirkpatrick directed his men to the main load-bearing joints.
11:44The connection points where vertical and diagonal members met the lower cord.
11:49Those were the weak spots.
11:51Destroy those joints and the entire center span would collapse.
11:56They worked in teams of three.
11:58One man placing charges.
12:00One man securing them with wire.
12:02One man running detonator cord between positions.
12:05No talking.
12:06Just hand signals and urgent movement.
12:08They could hear German vehicles approaching.
12:11Engine noise echoing through the forest.
12:14Growing louder.
12:15Coming from the northeast along the only road that led to this crossing.
12:20By 10.30, they had placed eight charges.
12:23Not enough.
12:24A proper demolition of this bridge required at least 16.
12:27But eight might work if positioned correctly.
12:31Kirkpatrick made the decision.
12:33Connect what they had.
12:34Get off the bridge.
12:35Prepare to blow it the moment Germans appeared.
12:38His men were running wire back to the detonation position when the first German vehicle came into view.
12:44A Schwimmwagen.
12:45German scout car.
12:47Four SS soldiers inside.
12:49Moving fast.
12:51The vehicle was 300 yards away when Kirkpatrick's forward observer spotted it.
12:56200 yards.
12:58Kirkpatrick's men were still connecting wire, still securing the detonator to the circuit.
13:02The Schwimmwagen was 100 yards away.
13:0650.
13:07The German driver saw Americans on the bridge.
13:10Started to break.
13:11Kirkpatrick triggered the charges.
13:13Six of the eight explosions fired.
13:16Two charges failed.
13:17The bridge lifted.
13:19Twisted.
13:20The center section dropped 10 feet but did not completely collapse.
13:24The structure was damaged, dangerously unstable, but technically still standing.
13:30The Schwimmwagen stopped, reversed, disappeared back into the forest.
13:35Kirkpatrick reported the partial success to Pergrin.
13:38Bridge severely damaged but possibly passable to German engineers with bridging equipment.
13:43Pergrin understood the implication.
13:47Piper would send his pioneer company forward.
13:49They would assess the damage, maybe attempt repairs, maybe throw a temporary span across the gap.
13:55The delay would be hours instead of minutes.
13:58But it was still a delay.
14:00And delays were killing the German offensive.
14:03By noon on December 17th, Kampfgruppe Piper had traveled less than 15 miles.
14:09The operational plan called for 60 miles on the first day.
14:12Piper was 45 miles behind schedule.
14:16Three demolished bridges.
14:18Multiple detours.
14:19Constant rerouting.
14:21And everywhere he turned, another group of American engineers was setting up roadblocks
14:26or wiring another crossing for demolition.
14:29Pergrin repositioned his companies.
14:31A company moved to Stavlo.
14:33Another critical bridge over the Amblev.
14:36German intelligence indicated Piper would attempt that crossing next.
14:40C company established positions at Verbumont.
14:42A road junction that controlled access to three separate routes west.
14:47B company remained mobile.
14:49Ready to respond wherever the German column appeared next.
14:52The casualties were mounting.
14:54Not from direct combat.
14:56From the work itself.
14:57Engineers under fire.
14:59Exposed positions.
15:00German artillery finding their locations.
15:03Stab sergeant Paul Hinkle was killed placing charges on a bridge approach at Stavlo.
15:09Corporal Michael Chen was wounded by German machine gun fire while cutting detonator wire.
15:14Private First Class Anthony Delgado drowned when he fell from a damaged bridge into the Amblev River while attempting to
15:22recover unused explosives.
15:24But the mission continued.
15:26Every bridge Piper needed was either destroyed or prepared for demolition.
15:31Every road junction was blocked or mined.
15:33Every fuel depot in his path was burned or evacuated.
15:37The 291st Engineer Combat Battalion was fighting a defensive action without firing more than a few dozen rifle shots.
15:45Their weapons were explosives and timing and technical knowledge.
15:49And it was working.
15:50Piper radioed 6th Panzer Army Headquarters at 1,300 hours.
15:55Requested updated intelligence on American positions.
15:58Requested air reconnaissance to identify intact bridges.
16:02Requested permission to break radio silence and coordinate with other Kampfgruppen advancing on parallel routes.
16:09His tone was professional, but his frustration was clear.
16:12The Engineer Battalion was destroying his timetable.
16:16His fuel situation was becoming critical, and he still had not reached the Meuse.
16:21But Pergrin faced a different problem.
16:23His explosives were running out.
16:25The battalion had started December 17th with approximately 4,000 pounds of C-4.
16:31By midday, they had used more than half.
16:34Additional supplies were being trucked forward from First Army depots,
16:38but those convoys were caught in the same traffic jams created by retreating American units.
16:43Pergrin calculated he had enough demolitions for perhaps six more bridges,
16:48maybe eight if his men were conservative with charge placement.
16:52After that, the 291st would have nothing left to blow.
16:55Pergrin requested emergency resupply at 1,400 hours.
17:00First Army acknowledged, but could not guarantee delivery time.
17:03The roads behind American lines were chaos.
17:06Supply trucks mixed with retreating infantry.
17:09Ambulances carrying wounded.
17:11Headquarters units evacuating.
17:13Artillery batteries repositioning.
17:15Nobody could move fast.
17:17Traffic was gridlocked for miles.
17:20So Pergrin improvised.
17:21He ordered his men to scavenge explosives from abandoned positions.
17:25Minefields left by retreating units.
17:28Demo charges prepared by other engineer battalions.
17:30Unexploded German ordnance if they could safely recover it.
17:34Anything that could bring down a bridge.
17:36His supply sergeant reported finding 200 pounds of TNT
17:40at an abandoned ammunition dump near Malmody.
17:43Another company located 300 pounds of composition explosive
17:47at a former forward command post.
17:49It was enough for three more bridges.
17:52Maybe four.
17:53Then the 291st would be out of options.
17:55The German advance continued.
17:57Piper captured Stavolot at 1630 despite American attempts to hold the town.
18:03The bridge demolition team had wired the crossing
18:05but hesitated to blow it while American vehicles were still trying to escape across the span.
18:10By the time they triggered the charges,
18:13German infantry was already on the western bank.
18:15The explosion killed 11 SS soldiers but failed to completely destroy the bridge.
18:21German engineers assessed the damage.
18:23Reported it was repairable within two hours.
18:26Piper now had his crossing.
18:28His Tigers moved into Stavolot, refueled from captured American dumps,
18:33continued west toward Trois-Ponts for a second attempt at that location.
18:37But this time, Piper split his force,
18:39sent a detachment north to Franco-Champs, another south toward Juan.
18:44Three separate thrusts, testing American defenses, looking for the weak point.
18:48Pergrin tracked all three columns.
18:51His observation posts reported German movement, radioed positions, and estimated strength.
18:56But the 291st was stretched thin.
18:59600 men covering dozens of potential crossing sites across a 20-mile front.
19:04They could not be everywhere, could not wire every bridge, could not stop every German probe.
19:09At Franco-Champs, a small bridge over the Old Rouge stream was captured intact.
19:16Piper's northern detachment secured it before American engineers arrived.
19:20The Germans immediately pushed reconnaissance vehicles across,
19:23sent scout patrols west to identify the next objective.
19:27Within 30 minutes, they had advanced two miles, encountered no resistance,
19:32radioed back that the route was clear.
19:34But the route was not clear.
19:36It was mined.
19:38Pergrin had ordered defensive minefields placed along every likely axis of German advance.
19:43His men had worked through the previous night,
19:45planting anti-tank mines at road junctions and narrow passages.
19:49The German scouts triggered the first mine at 1,700 hours.
19:53A Tiger hit a second mine three minutes later.
19:56The explosions disabled both vehicles, blocked the road.
20:00Piper's northern detachment stalled.
20:02The southern thrust toward Vanna encountered a different problem.
20:06No bridges.
20:08The engineers had already demolished every crossing along that route.
20:11The Germans reached the Lian Creek and found nothing but destroyed spans and impassable gaps.
20:17They tried to ford the creek, but the banks were too steep.
20:20The water too deep.
20:22Tiger tanks could not cross.
20:24Piper's southern detachment was stuck.
20:26That left only the main column, still pushing west from Stavalo, still trying to reach Trois-Ponds, still trying to
20:33break through to open country.
20:35They advanced four miles before encountering the next American roadblock.
20:39A company of the 291st, 40 engineers with rifles and two Browning machine guns.
20:45No anti-tank weapons.
20:47No artillery support.
20:49Just small arms and discipline.
20:50The German lead elements attacked at 1,800 hours, half-tracks carrying panzer grenadiers.
20:56They expected the Americans to retreat, expected token resistance, then withdrawal.
21:01But a company held position, opened fire at 300 yards, cut down the first wave of German infantry,
21:08disabled two half-tracks with concentrated machine gun fire, forced the Germans to deploy and take cover.
21:14The firefight lasted 17 minutes.
21:17The Germans brought up more infantry, started flanking movements.
21:21A company commander ordered withdrawal before his position was overrun.
21:25His men pulled back to a secondary position 500 yards west, left behind a prepared demolition on the road itself.
21:32Not a bridge, just a section of highway.
21:351,500 pounds of explosives buried under the pavement.
21:38The Germans advanced cautiously, cleared the American position, began moving vehicles forward.
21:44A tiger rolled over the buried demolition.
21:47The crew never knew what hit them.
21:49The explosion threw the 60-ton tank sideways off the road, destroyed the turret, killed the entire crew.
21:56The blast crater was 15 feet deep and 30 feet wide.
21:59Completely impassable.
22:01Piper was now 12 hours into his offensive.
22:04He had advanced 22 miles.
22:06The operational plan called for 70 miles by this point.
22:09He was 48 miles behind schedule.
22:11His fuel was critically low.
22:13His infantry had taken casualties.
22:16Three of his tigers were disabled or destroyed.
22:18And everywhere he turned, there were more American engineers.
22:22More demolished bridges.
22:23More roadblocks.
22:24More delays.
22:26At 1,900 hours, Piper received new orders from 6th Panzer Army.
22:30Continue the advance.
22:32Bypass obstacles where possible.
22:34Maintain momentum.
22:36Reach the Meuse within 24 hours.
22:37The entire northern offensive depended on Kampfgruppe Piper breaking through.
22:42But Piper could not maintain momentum.
22:45Not with every bridge destroyed.
22:46Not with American engineers contesting every mile.
22:49He made the decision to halt for the night.
22:52Consolidate his scattered columns.
22:54Reassess the situation.
22:56His men were exhausted.
22:5820 hours of continuous movement.
23:00Combat.
23:01Delays.
23:02They needed rest.
23:04Fuel.
23:05Ammunition resupply.
23:06The Germans established defensive positions around Stavalo.
23:10Set up command posts.
23:12Posted guards.
23:13Settled in for a few hours of sleep.
23:15They assumed the Americans would use the darkness to withdraw farther west.
23:19Assumed the morning would bring easier progress.
23:22They were wrong.
23:23Pergrin used the night for preparation.
23:25His companies moved into new positions while the Germans rested.
23:29Wired more bridges.
23:31Planted more mines.
23:32Established observation posts overlooking every route Piper might use at dawn.
23:36The engineers worked in darkness.
23:39No lights.
23:40No noise.
23:41Just silent movement and careful placement of explosives.
23:45They were running on adrenaline and coffee.
23:47And the knowledge that thousands of American lives depended on them buying more time.
23:52At 2200 hours, Pergrin received his first resupply convoy.
23:57Two trucks carrying explosives from 1st Army depots.
24:011800 pounds of C4.
24:03600 pounds of TNT.
24:05Enough demolitions for perhaps 10 more bridges.
24:08His supply sergeant distributed the material immediately.
24:12Sent runners to each company position with fresh explosives.
24:15Told them to wire every remaining crossing within their sector.
24:19The casualty reports continued through the night.
24:22Sergeant William Foster killed by German sniper fire while observing enemy positions near Stavalo.
24:28Private Robert Yamamoto wounded when his jeep hit a mine on a darkened road.
24:33Corporal James Murphy missing after his squad encountered a German patrol near Vanna.
24:38The 291st had lost 11 men killed and 37 wounded since the offensive began.
24:44Small numbers compared to infantry units, but devastating for a 600-man battalion.
24:51Pergrin also received intelligence updates.
24:53Other German columns were advancing on parallel routes.
24:56The 2nd Panzer Division was pushing toward Hufalize.
24:59The Panzer Lairdivision was attacking near Bastogne.
25:03The entire German offensive was unfolding across a 60-mile front.
25:08Kampfgruppe Piper was just one piece.
25:10But it was the most dangerous piece.
25:12The spearhead.
25:14The breakthrough force.
25:15If Piper reached the Meuse, the entire Allied position in Belgium would collapse.
25:201st Army headquarters wanted to know how long Pergrin could hold.
25:24How long before the Germans overwhelmed his positions.
25:27How long before Piper broke through.
25:30Pergrin calculated his remaining explosives.
25:33His casualties.
25:34His defensive positions.
25:35He estimated three more days.
25:38Maybe four if his men were lucky and aggressive.
25:41After that, the 291st would have nothing left.
25:44No explosives.
25:45No reserves.
25:46No options.
25:47Three days to stop the largest German offensive in the West since 1940.
25:52At 0300 on December 18th, Piper resumed his advance.
25:57His column moved out from Stavolo.
25:59Headed northwest toward La Glaze.
26:01Another small town.
26:03Another bridge.
26:04Another objective.
26:06His reconnaissance reported that the Americans had not had time to fortify La Glaze.
26:10Maybe the bridge would be intact.
26:12Maybe his Tigers could finally break into open country.
26:16But C Company of the 291st was already at La Glaze.
26:20Had been there since midnight.
26:21Lieutenant Harold Parker commanding.
26:23Twenty-eight engineers.
26:25They had wired the bridge.
26:27Mined the approaches.
26:28Set up firing positions in buildings overlooking the crossing.
26:32Parker radioed Pergrin at 0315.
26:35Reported his position ready.
26:37Requested permission to engage when Germans appeared.
26:40Pergrin approved.
26:41Told Parker to blow the bridge at the last possible moment.
26:44Extract his men safely.
26:46Avoid unnecessary casualties.
26:48The mission was delay.
26:50Not heroic last stands.
26:52Destroy the bridge and get out.
26:54The Germans reached La Glaze at 0430.
26:57Still dark.
26:59Piper sent infantry forward to probe the American positions.
27:02The SS soldiers moved cautiously.
27:05Expecting resistance.
27:07They encountered nothing.
27:09Advanced into the town center.
27:11Cleared several buildings.
27:12Found them abandoned.
27:14Radioed back that La Glaze appeared undefended.
27:17Piper ordered his Tigers forward.
27:19Three of them.
27:20Moving in column toward the bridge.
27:22The lead tank was 200 yards from the crossing when Parker opened fire.
27:27His machine guns raked the German infantry.
27:30Forced them to take cover.
27:32Killed six men in the first burst.
27:34The Tigers accelerated.
27:36Tried to reach the bridge before the Americans could react.
27:39Parker waited.
27:40Let them close the distance.
27:42100 yards.
27:4375.
27:4450.
27:45The explosion obliterated the bridge.
27:48Sent chunks of concrete flying 300 feet.
27:51The lead Tiger stopped at the edge of the crater.
27:53The commander climbed out.
27:55Surveyed the damage.
27:57Realized once again that American engineers had beaten him to the objective.
28:01Piper was reportedly in that tank.
28:03Watching his offensive disintegrate bridge by bridge.
28:07Mile by mile.
28:08By dawn on December 18th,
28:10Kampfgruppe of Piper had been stopped at six different locations.
28:14Habimont.
28:15Trois-Ponts.
28:16Neuf-Moulins.
28:17Stavelot.
28:19Francochamps.
28:20La Glaze.
28:20Every major crossing in his path was destroyed or damaged.
28:24His fuel situation was critical.
28:27His vehicles were spread across 10 miles of narrow roads.
28:30His infantry was exhausted.
28:32And he was now more than 50 miles behind his operational schedule.
28:36But Piper had one more option.
28:39One bridge the Americans might not have had time to wire.
28:43A crossing at Cheneau.
28:44Small village.
28:46Minor route.
28:47Maybe overlooked in the chaos.
28:49He ordered his column to turn south one more time.
28:52Race for Cheneau before the engineers arrived.
28:55Pergrin had anticipated Cheneau.
28:57His intelligence section had mapped every possible German route.
29:00Every bridge.
29:01Every Ford.
29:02Every crossing point within 30 miles.
29:05Cheneau was on the list.
29:07B Company received orders at 0500.
29:10Get to Cheneau.
29:11Wire the bridge.
29:12Be ready when Piper arrived.
29:14Lieutenant Frank Ray took one platoon.
29:17Fourteen men.
29:18They loaded explosives into two jeeps and raced south through darkness.
29:23The roads were icy.
29:25Visibility near zero.
29:27They drove without headlights to avoid German observation.
29:30Navigated by map and compass and memory of the terrain.
29:34Reach Cheneau at 0545.
29:36The bridge was a narrow stone arch over the Amblev.
29:40Old construction.
29:42Probably built in the 1800s.
29:44Strong enough for Tiger tanks.
29:46But vulnerable to properly placed demolitions.
29:49Ray's men unloaded C4.
29:51Moved onto the bridge.
29:52Started positioning charges against the arch keystones.
29:56They worked fast.
29:58German vehicle noise was audible from the northeast.
30:01Piper's column approaching.
30:02Maybe 15 minutes away.
30:04Maybe 10.
30:05They placed six charges.
30:07Wired them in series.
30:09Ran detonator cord back to a position in a stone barn 50 yards west of the bridge.
30:15Ray tested the circuit.
30:16Got a positive reading.
30:18The demolition was ready.
30:19His men took cover.
30:21Waited.
30:22Watched the eastern approach through gaps in the barn walls.
30:26The first German vehicle appeared at 0612.
30:29A Panther tank.
30:30Then another.
30:32Then three more.
30:33Behind them came half tracks.
30:35More Panthers.
30:36Tiger tanks.
30:37The entire weight of Kampfgruppe Piper rolling toward this one narrow bridge.
30:43Ray counted vehicles.
30:44Radioed the information to Pergrin.
30:47Estimated at least 40 armored vehicles in the column.
30:50Maybe more following.
30:52The lead Panther reached the bridge approach.
30:54Slowed.
30:55The commander was scanning for threats.
30:58Looking for signs of American positions.
31:00His tank inched forward onto the bridge deck.
31:03The second Panther followed.
31:05Ray kept his hand off the detonator.
31:07Let them commit.
31:08Let more vehicles move onto the span.
31:11Maximize the effect.
31:13Three Panthers were on the bridge when Ray triggered the charges.
31:16The blast was massive.
31:18Much larger than previous demolitions.
31:20The entire center section of the arch collapsed.
31:23All three Panthers dropped into the river.
31:2630 feet straight down.
31:28The vehicles crashed onto rocks.
31:30Burst into flames.
31:32Crew members who survived the fall tried to escape through hatches.
31:35Most did not make it.
31:37Piper's column stopped.
31:39German infantry dismounted.
31:41Started returning fire toward the American position.
31:44Rhea pulled his men out through the back of the barn.
31:46They moved west through forest.
31:48Avoided roads.
31:50Reached their rally point two miles away without casualties.
31:53Mission accomplished.
31:55Another bridge destroyed.
31:57Another delay inflicted on Kampfgruppe Piper.
32:00By noon on December 18th, the situation was clear.
32:03Piper was trapped.
32:04Surrounded on three sides by American forces.
32:08His fuel exhausted.
32:09His vehicles immobilized.
32:11His infantry pinned in defensive positions around Le Glaze and Stumont.
32:15The 82nd Airborne Division had moved into blocking positions north of his column.
32:20The 30th Infantry Division held positions to the west.
32:23The 7th Armored Division controlled routes to the south.
32:26Kampfgruppe Piper was contained.
32:28The German offensive continued elsewhere.
32:31Other Panzer Divisions made progress toward Bastogne.
32:34The 2nd Panzer Division advanced to within four miles of the Meuse River at Donat.
32:39But without Piper breaking through in the north, the entire operation was failing.
32:43The 6th Panzer Army had stalled.
32:46The breakthrough to Antwerp was impossible.
32:49Hitler's last offensive in the west was collapsing.
32:52Pergrin received new orders at 1,500 hours.
32:55The 291st would remain in defensive positions around Malmody.
32:59Continue blocking any German attempts to reinforce Piper.
33:02Continue denying river crossings.
33:041st Army was bringing up armored divisions to counterattack.
33:08Infantry reinforcements were moving into position.
33:10The engineers had bought enough time.
33:13Now, the combat troops would finish the job.
33:16But the battle was not over for the 291st.
33:19German artillery began targeting Malmody at 1,600 hours.
33:23Heavy shells.
33:24Probably 150mm guns.
33:27The bombardment continued for three hours.
33:30Damaged buildings.
33:31Destroyed vehicles.
33:32Created casualties among rear area personnel.
33:35The engineers took cover in cellars and stone buildings.
33:39Waited for the shelling to stop.
33:41At 1730, a reconnaissance patrol from C Company discovered something horrifying.
33:47Bodies in a field near the Barnier Crossroads.
33:50American soldiers.
33:51Approximately 80 men.
33:53All shot.
33:54Most had their hands raised in surrender when they were killed.
33:58The massacre had occurred on December 17th.
34:01Battery B of the 285th Field Artillery Observation Battalion.
34:05They had been captured by Kampfgruppe Piper.
34:08Lined up in the field.
34:10Machine gunned.
34:1117 survivors were found hiding in a cafe basement nearby.
34:15Wounded.
34:16Freezing.
34:17Traumatized.
34:18They reported that SS soldiers had murdered their entire battery.
34:22The survivors had played dead.
34:25Waited until the Germans moved on.
34:26Then crawled to safety.
34:28Pergren reported the massacre to 1st Army Headquarters.
34:31Requested medical evacuation for the survivors.
34:35Requested graves registration teams for the bodies.
34:38The news spread through the 291st within hours.
34:41The engineers had been fighting a professional military operation.
34:45Blowing bridges.
34:47Creating delays.
34:48Standard combat engineer missions.
34:50But now they knew they were facing something different.
34:53War criminals.
34:54Soldiers who murdered prisoners.
34:56The motivation changed.
34:58This was no longer about buying time for withdrawal.
35:01This was about stopping an enemy who committed atrocities.
35:05Pergren addressed his battalion that evening.
35:07Told them what had happened at Baunier.
35:10Told them the Malmedy Massacre would not be forgotten.
35:13Told them their work destroying bridges had prevented Piper from reaching more American units.
35:18Had saved lives.
35:20Had stopped the breakthrough.
35:21The engineers had done their job.
35:23And they would continue doing it until the Germans were defeated.
35:26On December 19th, the weather cleared.
35:30American fighter bombers attacked Piper's trapped column.
35:33Destroyed vehicles.
35:35Killed SS soldiers.
35:36Cut off any possibility of German retreat.
35:40By December 21st, Kampfgruppe Piper was finished.
35:43Out of fuel.
35:45Out of ammunition.
35:46Surrounded.
35:47Piper abandoned his vehicles.
35:49Led his surviving men east on foot through American lines.
35:52Left behind all his tigers.
35:55All his panthers.
35:56All his equipment.
35:57The most powerful German battle group in the Ardennes offensive had been destroyed by air power and artillery and starvation
36:05and exhaustion.
36:06And by 600 combat engineers who refused to let them cross a single bridge intact.
36:11The Battle of the Bulge continued through January, but the outcome was decided.
36:16American forces counter-attacked.
36:18Pushed the Germans back.
36:20Recaptured lost ground.
36:22By late January, the front line had returned to its December 15th positions.
36:27The Germans gained nothing.
36:29Lost everything.
36:30Casualties exceeded 100,000 on both sides.
36:34Equipment destroyed.
36:35Divisions shattered.
36:37The Wehrmacht would never mount another major offensive in the West.
36:41The 291st Engineer Combat Battalion received the Presidential Unit Citation for actions from December 17th to December 26th.
36:50The citation recognized outstanding performance against numerically superior enemy forces.
36:57Mentioned specifically the bridge demolitions that stopped Kampfgruppe Piper.
37:02Acknowledged the battalion's role in delaying the German breakthrough.
37:05Pergrin was promoted to full colonel in February.
37:08His battalion remained in Belgium through winter.
37:12Built replacement bridges.
37:13Cleared minefields.
37:15Maintained supply routes.
37:17Other units called them the Bridge Killers.
37:19The engineers who stopped the SS.
37:22The battalion that saved the Ardennes.
37:25In early March 1945, Allied armies were advancing into Germany.
37:30The Rhine River remained the last major natural barrier protecting the German heartland.
37:35Every bridge across the Rhine had been destroyed by retreating German forces.
37:40The river was 300 yards wide in most places.
37:43Fast current.
37:44Steep banks.
37:45Crossing would require major assault operations with massive casualties.
37:50Except at Remagen.
37:51On March 7th, the 9th Armored Division reached Remagen.
37:56Found the Ludendorff Bridge still standing.
37:59Germans had attempted demolition, but the charges failed.
38:02Only partial damage.
38:04The bridge was weak, but intact.
38:06American forces charged across.
38:09Secured the Eastern Bank.
38:10Established a bridgehead in Germany.
38:13First Army recognized the opportunity.
38:15Every available unit was ordered to Remagen.
38:18Cross the bridge.
38:19Expand the bridgehead.
38:21Get troops into Germany before German counterattack.
38:25Within hours, divisions were moving toward Remagen.
38:28Thousands of vehicles.
38:30Tens of thousands of soldiers.
38:31All using one damaged bridge.
38:34The Ludendorff Bridge was not designed for this traffic.
38:38Railroad bridge.
38:39Built in World War I.
38:41Already weakened by failed demolition.
38:44Engineers inspected the structure.
38:46Reported serious concerns about load capacity.
38:49The bridge might collapse at any time.
38:52First Army needed alternatives.
38:54Backup crossings.
38:56Additional bridges to handle traffic volume.
38:58On March 8th, Pergren received orders.
39:01The 291st would build a treadway bridge across the Rhine at Remagen.
39:06Full tactical bridge.
39:08Capable of supporting tanks and heavy vehicles.
39:11Operational within 48 hours.
39:13Before the Ludendorff Bridge collapsed.
39:15Before Germans organized effective counterattacks.
39:19Pergren studied specifications.
39:21Treadway bridge required floating pontoons.
39:24Steel sections.
39:25Anchoring systems.
39:27The river was 900 feet wide at Remagen.
39:30Bridge would stretch over 1,000 feet, counting approach ramps.
39:34Longest tactical bridge built under fire in the entire European theater.
39:38His battalion had built dozens of bridges across France and Belgium.
39:42Small rivers.
39:44Narrow streams.
39:45Nothing approaching Rhine's scale.
39:47And those bridges were built behind friendly lines.
39:50Not under German artillery fire.
39:53Not with Luftwaffe bombing.
39:54Not while enemy actively tried to destroy construction.
39:58The 291st reached Remagen on March 9th.
40:01Began assembling equipment at 0830.
40:04Bridge would use inflatable rubber pontoons.
40:07Each pontoon, 33 feet long.
40:108 feet wide.
40:111,000 pounds.
40:1332 pontoons needed to span the river.
40:16Pontoons had to be inflated.
40:18Positioned in current.
40:20Anchored to riverbed.
40:21Then connected with steel treadway sections.
40:24Pergrin divided men into construction teams.
40:27Each team responsible for specific sections.
40:30Some inflated pontoons on Western Bank.
40:32Others prepared anchoring systems.
40:35Others assembled steel treadway sections.
40:38Work required precise coordination.
40:40One mistake, an entire bridge could fail.
40:44Twist in current.
40:45Break apart.
40:46German observers on Eastern Hill saw construction beginning.
40:50Artillery shells started falling at 0900.
40:53105 millimeter rounds.
40:56Landing in river.
40:57On banks.
40:58Near assembly areas.
41:00Engineers kept working.
41:02Moved pontoons into position despite shelling.
41:05Connected anchor lines.
41:07Pushed first sections into current.
41:09The Rhine flowed at 7 miles per hour.
41:12Fast enough to sweep away unsecured pontoons.
41:14Strong enough to pull men under water.
41:18Water temperature, 38 degrees.
41:21Survival time, maybe 10 minutes before hypothermia.
41:24Engineers worked in that river.
41:27Waist deep.
41:28Chest deep.
41:29Connecting pontoons.
41:30Securing anchors.
41:32Fighting current.
41:33Ignoring artillery.
41:35By noon, they had completed 100 feet.
41:38Another 800 feet remaining.
41:40German shelling intensified.
41:42Added 150 millimeter guns.
41:45Heavy rounds.
41:47Enormous explosions.
41:48One direct hit killed Private Edward Morrison.
41:52Wounded five others.
41:53Construction continued.
41:55Pergren ordered faster work.
41:57Ludendorff Bridge showed new cracks.
42:00Might collapse within 24 hours.
42:02Treadway Bridge had to finish first.
42:05At 1300 hours, Luftwaffe appeared.
42:08Stukas.
42:09Me 262 jets.
42:11Diving toward construction site.
42:13American anti-aircraft guns opened fire.
42:17Shot down two aircraft.
42:18Damaged others.
42:20But some got through.
42:21Dropped bombs near pontoons.
42:24Created water geysers.
42:25Explosions threw engineers into river.
42:28Some pulled out.
42:30Others disappeared in current.
42:32The battalion kept building.
42:34Through artillery.
42:35Through air attacks.
42:37Through casualties.
42:38By 1500 hours, they had completed 300 feet.
42:42Quarter of the bridge.
42:43But the pace was too slow.
42:45At current rate, completion would take 50 hours.
42:49Not 48.
42:50Pergren radioed for additional help.
42:53First Army sent two treadway companies.
42:55988th and 998th.
42:57Extra men.
42:58Extra equipment.
43:00Extra hands to speed construction.
43:02The reinforcements arrived at 1600 hours.
43:06Fresh engineers.
43:07Extra pontoons.
43:08More steel sections.
43:10The pace accelerated.
43:12Multiple teams working simultaneously.
43:15Some on western sections.
43:16Some pushing into mid-river.
43:18Some preparing eastern approaches.
43:20The bridge grew faster.
43:22The bridge grew faster.
43:23200 feet per hour now instead of 100.
43:26German artillery continued throughout the night.
43:29Shells landing every few minutes.
43:31Searchlights illuminated the construction site.
43:34Made the engineers perfect targets.
43:36But also allowed work to continue in darkness.
43:39The battalion accepted the trade.
43:41Visibility for vulnerability.
43:43Speed for safety.
43:46Every hour mattered.
43:48At 0300 on March 10th, a German shell scored direct hit on assembled pontoon sections waiting
43:54on the western bank.
43:55The explosion destroyed four pontoons.
43:58Killed three engineers from the 988th Treadway Company.
44:02Wounded 11 more.
44:04Set back construction by two hours.
44:06Pergrin ordered immediate replacement pontoons brought forward.
44:10The work continued.
44:12By dawn on March 10th, the bridge stretched 700 feet.
44:16Just 200 feet remaining.
44:18But those final 200 feet were the most difficult.
44:21Eastern Bank was under direct German observation.
44:25Enemy artillery could target the exact connection point.
44:28Every man working on that final section was completely exposed.
44:33Lieutenant Harold Dawson volunteered to lead the final connection team.
44:3715 engineers.
44:38They moved on to the incomplete eastern end at 0630.
44:43German shells began falling immediately.
44:46Dawson's team worked through the barrage.
44:48Positioned the last pontoons.
44:51Connected steel treadway sections.
44:53Secured anchor lines.
44:55Three men were wounded, but none killed.
44:57By 0700, the eastern end was anchored to the bank.
45:01Final connection required linking eastern and western sections in midriver.
45:05The floating sections had to align perfectly.
45:08Any gap in vehicles could not cross.
45:10Any misalignment, and the bridge would twist apart in the current.
45:15Engineer teams worked from both directions, inching the sections together,
45:19adjusting for current drift, fighting to maintain position.
45:23At 1,000 hours on March 10th, the final connection was made.
45:271,032 feet of floating bridge across the Rhine River.
45:31Built in 32 hours, under constant German fire.
45:35The longest tactical bridge constructed during World War II.
45:391st Army immediately began moving vehicles across.
45:43Tanks, artillery, supply trucks.
45:46Within hours, thousands of troops were crossing into Germany.
45:49At 1,500 hours on March 17th, the Ludendorff Bridge collapsed, just as engineers predicted.
45:56The structure gave way under accumulated damage and stress.
46:00Fell into the Rhine.
46:02Killed 28 engineers who were working on repairs.
46:04Injured 93 others.
46:07But by then, the Treadway Bridge was handling all traffic.
46:11Two additional pontoon bridges had been completed.
46:13The Remagen Bridgehead was secure.
46:16Over 125,000 American troops crossed the Rhine at Remagen,
46:20using bridges built by combat engineers.
46:23The Bridgehead allowed 1st Army to drive deep into Germany,
46:27encircle the Ruhr Industrial Area,
46:29capture hundreds of thousands of German troops.
46:32The war in Europe ended eight weeks later.
46:34The 291st Engineer Combat Battalion completed 73 bridges during the war.
46:4019 built under enemy fire.
46:42Cleared 7,000 mines.
46:44Demolished six bridges to stop German advances.
46:47Lost eight men killed in action.
46:4993 wounded.
46:51Out of 600 who served,
46:52the most decorated combat engineer battalion in the European theater.
46:56Pergren returned to civilian life in 1945.
47:00Worked as railroad executive for Pennsylvania Railroad.
47:03Later, Penn Central.
47:05Retired as vice president and chief engineer.
47:07Published his memoir, First Across the Rhine, in 1989.
47:11The book documented the battalion's role in stopping comp group Piper
47:15and building the Remagen Bridge.
47:17Became required reading at Army Engineer School.
47:20Col. David Pergren died April 7, 2012, three months before his 95th birthday.
47:27He was buried with full military honors.
47:30His legacy lives in every combat engineer who understands that sometimes the most important weapon is not a rifle,
47:37but timing and technical knowledge and courage to stand your ground when tanks are approaching.
47:42The bridge at Remagen is gone.
47:45The Ludendorff Towers remain as a museum.
47:48Inside are photographs of the 291st building their Treadway Bridge.
47:52Documents from the Battle of the Bulge.
47:55Pergren's Silver Star and Purple Heart.
47:57The presidential unit citation.
47:59Visitors can stand where American engineers worked under fire.
48:03Can see the river they crossed.
48:05Can understand what 600 men accomplished in December 1944 and March 1945.
