On 16 December 1944 the Wehrmacht launched an offensive in the Ardennes region of Belgium, breaking through Allied lines and rapidly advancing towards Antwerp. On the afternoon of 17 December, General Eisenhower, the Supreme Allied Commander, decided to commit his theater reserve to the Ardennes in an attempt to halt the German advance; this consisted of the 17th, 82nd and 101st Airborne Divisions under the control of XVIII Airborne Corps. The three divisions were to be attached to Courtney Hodges's U.S. First Army and were ordered to concentrate around the town of St Vith. However, while the other two airborne divisions were able to immediately make their way to the Ardennes as they were already stationed in France, bad weather prevented the 17th from flying in from where the division was stationed in Britain for several days. On 23 December the weather cleared and the division was finally flown to France by emergency night flights. It moved to an assembly area near Rheims. On Christmas Day, the division was attached to George Patton's U.S. Third Army and ordered to assume a thirty-mile long defensive position that ran along the Meuse River near Charleville.
