The Ruhr Pocket was a battle of encirclement that took place in march 1945, on the Western Front near the end of World War II, in the Ruhr Area of Germany. Some 317,000 German troops, consisting mostly of unarmed Volksturm militia and Hitlerjugend units were taken prisoner along with 24 generals. The Americans lost 10,000 men, including 2,000 killed or missing.
Exploiting the capture of the Ludendorff Bridge at Remagen on 7 March, the U.S. 12th Army Group under General Omar Bradley advanced rapidly into German territory south of Field Marshal Walter Model's Army Group B. In the north, the Allied 21st Army Group under Field Marshal Bernard Montgomery crossed the Rhine in Operation Plunder on 23 March. The lead elements of the two Allied army groups linked up on 1 April 1945 east of the Ruhr Area to create a massive encirclement of 370,000 German troops to their west.
While the bulk of the U.S. forces advanced east towards the Elbe river, some 18 U.S. divisions remained behind to destroy the isolated forces of Army Group B. The reduction of the German pocket was begun right away on 1 April by the U.S. Ninth Army, with the forces of the U.S. First Army joining on 4 April. For 13 days the Germans delayed or resisted the U.S. advance. On 14 April, the First and Ninth Armies linked up, splitting the German pocket in half and German resistance began to crumble.
Having lost contact with its units, the German 15th Army capitulated the same day. Model dissolved his army group on 15 April and ordered the Volksturm and non-combatant personnel to discard their uniforms and go home. On 16 April the bulk of the German forces surrendered en masse to the U.S. divisions. Organized resistance came to an end on 18 April. Unwilling to surrender with his rank of Field Marshal into Allied captivity, Model committed suicide on the afternoon of 21 April.
