It was the second day of Operation Plunder. British and American divisions had crossed the river Rhine in force while airborne troops had landed to establish a bridgehead for them. Then it was time to extend that bridgehead before the Germans could organize a defensive line. In the morning of 25 March, British armored infantry supported by tanks and tank destroyers moved out to open a corridor for following units. The beginning of the attack started well, but then the British ran into an outpost of Fallschirm-Artillerie–Regiment 7.
