The Battle of Hürtgen Forest (German: Schlacht im Hürtgenwald) was a series of battles fought from 19 September to 16 December 1944, between American and German forces on the Western Front during World War II, in the Hürtgen Forest, a 140 km2 (54 mi2) area about 5 km (3.1 mi) east of the Belgian–German border. Lasting 88 days, it was the longest battle on German ground during World War II and it is the second longest single battle the U.S. Army has ever fought after the three-month-long Battle of Bataan.
The U.S. commanders' initial goal was to pin down German forces in the area to keep them from reinforcing the front lines farther north in the Battle of Aachen, where the US forces were fighting against the Siegfried Line network of fortified industrial towns and villages speckled with pillboxes, tank traps, and minefields. The Americans' initial tactical objectives were to take the village of Schmidt and clear Monschau. In a second phase the Allies wanted to advance to the Rur River as part of Operation Queen.
Generalfeldmarschall Walter Model intended to bring the Allied thrust to a standstill. While he interfered less in the day-to-day movements of units than at the Battle of Arnhem, he still kept himself fully informed on the situation, slowing the Allies' progress, inflicting heavy casualties, and taking full advantage of the fortifications the Germans called the Westwall, and which the Allies knew as the Siegfried Line. The Hürtgen Forest cost the U.S. First Army at least 33,000 killed and wounded, including both combat and non-combat losses, with upper estimates at 55,000; German casualties were 28,000. The city of Aachen in the north eventually fell on 22 October at high cost to the U.S. Ninth Army, but they failed to cross the Rur river or wrest control of its dams from the Germans. The battle was so costly that it has been described as an Allied "defeat of the first magnitude," with specific credit given to Model.
The Germans fiercely defended the area because it served as a staging area for the 1944 winter offensive Wacht am Rhein (known in English-speaking countries as the Battle of the Bulge), and because the mountains commanded access to the Rur Dam at the head of the Rur Reservoir (Rurstausee). The Allies failed to capture the area after several heavy setbacks, and the Germans successfully held the region until they launched their last-ditch offensive into the Ardennes. This was launched on 16 December and ended the Hürtgen offensive. The Battle of the Bulge gained widespread press and public attention, leaving the battle of Hürtgen Forest less well remembered.
The overall cost of the Siegfried Line campaign in American personnel was close to 140,000.
By mid-September 1944, the Allied pursuit of the German army after the landings at Normandy was slowing down due to extended supply lines and increasing German resistance. The next strategic objective was to move up to the Rhine River along its entire length and prepare to cross it. Courtney Hodges′ First Army experienced hard resistance pushing through the Aachen Gap and perceived a potential threat from enemy forces using the Hürtgen Forest as a base.
The U.S. 1st Infantry Division arrived in early October, joining elements of the XIX Corps and VII Corps, which had encircled Aachen. Although the 1st Infantry Division called for the surrender of the German garrison in the city, German commander Oberst Gerhard Wilck refused to capitulate until 21 October.
The Allies also thought it was necessary to remove the threat posed by the Rur Dam. The stored water could be released by the Germans, swamping any forces operating downstream. In the view of the American commanders, Omar Bradley, Hodges, and J. Lawton Collins, the direct route to the dam was through the forest.
Some military historians are no longer convinced by these arguments. Charles B. MacDonald—a U.S. Army historian and former company commander who served in the Hürtgen battle—has described it as "...a misconceived and basically fruitless battle that should have been avoided."
The Hürtgen Forest occupies a rugged area between the Rur River and Aachen. In the autumn and early winter of 1944, the weather was cold, wet, and cloudy, and often prevented air support. Apart from the poor weather, the dense forest and rough terrain also prevented proper use of Allied air superiority, which had great difficulties in spotting any targets. The dense conifer forest is broken by few roads, tracks, and firebreaks, it is also riven by deep ravines and had many steep slopes, restricting vehicular movement. The steep winding tracks sometimes turned into a muddy morass, further impeding vehicular traffic, especially heavy vehicles such as tanks. Equipment-laden infantry likewise had difficulty traversing the terrain, and often lost their footing on the slopes.
The German defenders had prepared the area with improvised blockhouses, minefields, barbed wire, and booby-traps, hidden by the mud and snow. There were also numerous concrete bunkers in the southern forests, mostly belonging to the deep defenses of the Siegfried Line, which were also centers of resistance. The dense forest allowed infiltration and flanking attacks, and it was sometimes difficult to establish a front line or to be confident that an area had been cleared of the enemy. The small numbers of routes and clearings in the forest had also allowed German machine gun, mortar, and artillery teams to pre-range their weapons and fire accurately. The dense forest also made navigation difficult, American infantry would sometimes have to request artillery fire to reorientate themselves.
The American advantage in numbers (as high as 5:1), armor, mobility, and air support was thus greatly negated by weather and terrain. In the forest, relatively small numbers of determined and prepared defenders could be highly effective. To exacerbate matters, as the American divisions took casualties, inexperienced replacements had to be fed directly into combat.
The densely forested terrain also limited the use of tanks and provided cover for German anti-tank teams equipped with Panzerfaust shaped-charge grenade launchers. The Allies made improvised rocket launchers, using rocket tubes from aircraft and spare Jeep trailers. Later in the battle, it proved necessary to blast tank routes through the forest. Transportation was similarly limited by the lack of routes: at critical times, it proved difficult to reinforce or supply front-line units or to evacuate the dead and wounded.
The Germans were hampered by much the same difficulties, worsened because their divisions had already taken heavy losses on the retreat through France and were hastily filled up with untrained boys and old men, often unfit for normal military service. Reinforcements thrown into the fighting include Arbeitsbattalion (work battalion) men and Luftwaffe officer cadets. Transportation was also a problem, because of the difficult roads and the lack of trucks and fuel; most supplies had to be manhandled to the front line. Nonetheless, despite increasing numbers of replacements lacking experience, German defenders had the advantage in that their commanders and many of their soldiers had been fighting for years, many had learned the necessary tactics for fighting efficiently in winter and forested areas. German commanders could also rely on local foresters for accurate intelligence. The Americans on the other hand were often better trained but inexperienced.
The Hürtgen Forest lay within the area of the U.S. First Army under Hodges. Responsibility fluctuated between the V Corps and VII Corps.
At the start, the forest was defended by the German 275th and 353rd Infantry Divisions; understrength but well prepared—5,000 men (1,000 in reserve)—and commanded by Generalleutnant Hans Schmidt. They had little artillery and no tanks. As the battle progressed, German reinforcements were added. American expectations that these troops were weak and ready to withdraw were overly optimistic.
