Allied forces landed in Algeria with Operation Torch on 8 November 1942. Beginning on 10 November, the British First Army under Kenneth Anderson began to advance toward Tunis. For the next six months, Tunisia was a battlefield as Axis and Allied forces fought on northern and southern fronts. In February 1943 the Axis won a victory at the Battle of Kasserine Pass, the first major engagement involving American troops, but the Operation Ochsenkopf offensive at the end of the month failed to stop the Allied advance. The Battle of Longstop Hill cleared the road to Tunis, which fell on 7 May. All Axis forces in Tunisia surrendered in the following days.
