Battle of the Bulge
Eisenhower wanted Montgomery to go on the counter offensive on 1 January, with the aim of meeting up with Patton's advancing Third Army and cutting off most of the attacking Germans, trapping them in a pocket. However, Montgomery, refusing to risk underprepared infantry in a snowstorm for a strategically unimportant area, did not launch the attack until 3 January, by which time substantial numbers of German troops had already managed to fall back successfully, but at the cost of losing most of their heavy equipment.
