The Division entered the Ardennes campaign, 4 January to 9 January, at the Battle of Dead Man's Ridge. It captured several small Belgian towns and entered Flamierge, 7 January, but enemy counterattacks necessitated a withdrawal. During the battle for Flamierge, S/Sgt I.S. Jachman was killed - he was posthumously awarded the Medal of Honor[link]. However, constant pressure and aggressive patrolling caused the enemy to retreat to the Ourthe River. On 18 January, the Division relieved the 11th Armored Division at Houffalize, pushed enemy remnants from the Bulge, and seized Wattermal and Espeler, 26 January. Coming under the III Corps, the 17th turned toward Luxembourg, taking Eschweiler and Clervaux and clearing the enemy from the west bank of the Our River. Aggressive patrols crossed the river to probe the Siegfried Line defenses and established a limited bridgehead near Dasburg before being relieved by the 6th Armored Division, 10 February.
A period of reequipment and preparation began. Taking off from marshalling areas in France, the 17th dropped into Westphalia in the vicinity of Wesel, 24 March. Operation Varsity was the first airborne invasion over the Rhine into Germany itself. On the 25th, the Division had secured bridges over the Issel River and had entrenched itself firmly along the Issel Canal. Moving eastward, it captured Haltern, 29 March, and Münster, 2 April. The 17th entered the battle of the Ruhr Pocket, relieving the 79th Infantry Division. It crossed the Rhine-Herne Canal, 6 April, and set up a secure bridgehead for the attack on Essen. The "Pittsburgh of the Ruhr" fell, 10 April, and the industrial cities of Mülheim and Duisburg were cleared in the continuing attack. Military government duties began, 12 April, and active contact with the enemy ceased, 18 April. The Division came under the XXII Corps24 April. It continued its occupation duties until 15 June1945 when it returned to France for redeployment.
It was deactivated on September 16, 1945, but reactivated on July 3, 1948 as a training unit at camp Picket VA, to absorb the influx of draftees occasioned by the Berlin Airlift crisis.
