Battle of Losheim Gap

The Losheim Gap is a long, narrow valley at the western foot of the Schnee Eifel, on the border of Belgium and Germany. Most accounts of World War II describing the Battle of the Bulge focus on the attack by the Germans around the Siege of Bastogne and the Battle of St. Vith, while the Germans' primary ambitions were actually anchored in taking the Losheim Gap. In this region of the border between Belgium and Germany, it is the only region conducive to military movement.
In 1944, "Unternehmen "Wacht am Rhein"" (Operation "Watch on the Rhine") was planned by Hitler to trade space for time by an attack which would advance through the Allied armies to Antwerp. This would be through "the Ardennes, a region that had long fascinated Hitler, where German armies had attacked with tremendous success 1914 and again, at Hitler’s personal instigation, in 1940 ... (but not also, as is often erroneously remarked, in 1870. That advance was from the Saar-Palatinate through the Wissembourg Gap into Alsace)".
Strategic importance.
During 1940 when the Germans invaded Belgium and then France, Field Marshal Erwin Rommel’s division sped through the Losheim Gap to gain the Meuse River and then push onto the English Channel. Hitler held similar hopes for 1944.
Battle of the Schnee Eifel.
On 15 September 1944 the U.S. 8th Infantry Regiment attached to 4th Division of V Corps was directed by division commander General Barton to advance from the border village of Schoenberg along the valley of the upper Our river. However, they didn't succeed because of multiple factors, hitting definite resistance first at the approaches to Losheim and later near the village of Roth.
During the Battle of the Bulge.
During the Battle of the Bulge, some of the best German units, including the 3rd Fallschirmjaeger Division and Sixth Panzer Army planned to assault northwest over the Losheim-Losheimergraben road and along the railroad tracks through the Losheim Gap in force towards the twin villages of Rocherath and Krinkelt but were held up by the broken railroad overpasses.
Led by the 1st SS Panzer division, they planned to attack the 2nd and 99th Infantry Divisions with the goal of capturing Losheimergraben and gaining access to the vital road network to its north and west that would allow them to capture the important port of Antwerp.
In a calculated risk, the Allies had only a few troops stretched very thinly across a wide area. Lanzerath, a village of about 15 homes, lay about to the west of Losheim. It was on the border between U.S. VIII Corps to the south and U.S. V Corps. It was held by a single Intelligence and Reconnaissance Platoon of 18 men and Task Force X, a tank destroyer platoon of 55 men.
The German forces were located on the eastern edge of the Losheim Gap in Losheim and further east. The Siegfried Line between them divided the Losheim Gap.
Dietrich's plan was for the 6th SS Panzer Army to advance east through Lanzerath and Bucholz Station and then drive through Honsfield and Büllingen. The infantry would continue north through Losheimergraben to push the 2nd and 99th Divisions out of the way. This would allow the 12th SS Panzer Division to advance eastward towards a group of villages named Trois-Ponts, connect to Belgian Route Nationale N-23, and cross the River Meuse. It was then another to Antwerp.
During their earlier retreat, the Germans had destroyed two key railroad overpasses which they planned to repair on the first day of the counterattack. Unable to quickly repair the railroad bridge, the units advanced instead into Lanzerath. In a day-long battle, they took dozens of casualties and were held up by the 18 remaining US troops dug into a ridge overlooking the village, and the 6th Panzer Army advance was delayed.
On December 17, German engineers repaired one of the road bridges over the railroad along the Losheim-Losheimergraben road and the 12th Division German armor began advancing towards the key road junction at Losheimergraben.
Once past Lanzerath, the Germans plan to capture the good quality road network was thwarted by mostly untried U.S. troops who succeeded in severely limiting the German's advance, halting them at Elsenborn Ridge. The Germans were forced to reroute their armor and troops to the south over mostly single-lane country roads, severely limiting the speed of their advance and their ability to concentrate their strength on the limited American defenses.
In the south, the 5th Panzer Army was given the task of capturing St. Vith and the vital road and rail network it controlled. The 18th Volksgrenadier Division under the command of Generalmajor Günther Hoffmann-Schönborn patrolled the Schnee Eifel area. On December 16 at 4:00 a.m., they took the twenty-two foot macadam road route following the Our River valley towards Manderfield. The route terminated at several vital crossroads in the city of St. Vith. The 5th Panzer Army planned to bypass St. Vith to the north.
Advance delayed.
 On the German side of the Siegfried Line, the Germans positioned their troops and armor around and to the east of the village of Losheim. On December 16, 1944, at 5:30 a.m., the Germans launched a 90-minute artillery barrage using 1,600 artillery pieces across an front.
The infantry of the 9th Fallschirmjaeger Regiment, 3rd Fallschirmjaeger Division led the way through the Losheim Gap, tasked with clearing American resistance along the main line of advance. To spare the armor, they operated in advance of Kampfgruppe SS Standartenführer Joachim Peiper's 1st SS Panzer Division, the spearhead of SS Oberstgruppenführer Sepp Dietrich’s Sixth Panzer Army. The infantry would then secure the right flank of the attack route near Losheimergraben.
The 12th Volksgrenadier Division reached Losheimgraben at 7:00 a.m. East of Losheim, Kampfgruppe Peiper expected to reach Losheimgraben by 8:00 a.m., but the tanks were held up for most of the morning of December 16 on the Blankenheim-Schnied road which was congested with horse-drawn artillery, infantrymen, and numerous other vehicles. Peiper himself tried to sort out the mess at one crossroads. For unknown reasons German engineers did not begin repairing the first of the railroad overpasses on the Losheim-Losheimergraben road until nearly noon, and the second was not repaired until December 17.
When Peiper got word that the overpass would not be repaired in time for his advance, he chose to move west through Lanzerath. He was frustrated and angry that the 9th Fallschirmjaeger Regiment had yet to report that the road was clear. The 500 troops of the 1st Battalion, 9th Fallschirmjaeger Regiment, 3rd Fallschirmjaeger Division were held up for most of the day by 18 men of the Intelligence and Reconnaissance Platoon, 394th Infantry Regiment, 99th Infantry Division at Lanzerath Ridge. At 6:00 pm, Peiper finally learned that the village had been secured. His column of 117 tanks, 149 half-tracks, 18 105mm guns and 6 150mm guns, totaling 600 vehicles, finally moved forward. He was further held up when his tanks struck two of their own minefields, slowing progress while the engineers cleared the fields ahead of mines.
Peiper finally arrived in Lanzerath near midnight only to find the infantry bedding down for the night. Every officer he spoke to said the woods were full of Americans and tanks. He furiously interrogated the infantry officers to learn if any patrols into the woods had been conducted and learned that no one had personally reconnoitered the area. Disgusted, Peiper demanded that Oberst Helmut von Hoffman, commander of the 9th Parachute Regiment, give him a battalion of paratroops to accompany his tanks. At 4:30 a.m. on December 17, more than 16 hours behind schedule, the 1st SS Panzer Division rolled out of Lanzerath with a battalion of paratroopers preceding them and headed east for Bucholz Station.
Advance towards Hünningen.
At Bucholz Station, the 3rd Battalion of the U.S. 394th Infantry Regiment was surprised and quickly captured, except for a headquarters company radio operator. Hidden in a cellar, he called in reports to division headquarters until he was finally captured. Driving west-northwest, the Germans entered Honsfeld, where they encountered one of the 99th Division's rest centers, clogged with confused American troops. They killed many and destroyed a number of American armored units and vehicles. Peiper easily captured the town and of fuel for his vehicles. He then advanced towards Büllingen, keeping to the plan to move west, apparently unaware he had nearly taken the town and unknowingly bypassing an opportunity to flank and trap the entire 2nd and 99th Division. Peiper suddenly turned south to detour around Hünningen, interested only in getting back onto his assigned Rollbahn. Kampfgruppe Peiper a few days later gained notoriety for their murder of U.S. prisoners of war in what became known as the Malmedy massacre.
Losheimergraben attack.
The task of defeating the 99th Division was the objective of 12th SS Panzer Division reinforced by additional Panzergrenadier and Volksgenadier divisions. On December 17, German engineers repaired one of the road bridges over the railroad along the Losheim-Losheimergraben road and the 12th Division German armor began advancing towards the key road junction at Losheimergraben and the twin villages of Rocherath and Krinkelt. However, in more than ten days of intense battle, they were unable to dislodge the Americans from Elsenborn Ridge, where elements of the V Corps of the First U.S. Army prevented the German forces from reaching the road network to their west.
The German advance never recovered from its initial delay, and the Sixth Panzer Army only got as far as La Gleize before its advance stalled out, advancing less than half-way to the River Meuse. The remaining soldiers were left to find their own way back to the east.
