After the battle
Eisenhower, with the support of Roosevelt and Churchill, appointed Darlan as the leader of French North Africa. Charles de Gaulle of the Free French responded with fury. The problem vanished when a local French anti-Nazi, Ferdinand Bonnier de la Chapelle, assassinated Darlan on December 24, 1942. Henri Giraud, who had been hanging around since November, became the new leader.
After consolidating in French territory the Allies struck into Tunisia. Forces in the British 1st Army under General Kenneth Anderson almost reached Tunis before a counterattack at Djedeida by German troops under General Walther Nehring thrust them back. In January 1943 German troops under General Erwin Rommel retreating westwards from Libya reached Tunisia.
The British 8th Army in the east, commanded by General Bernard Montgomery, stopped around Tripoli to allow reinforcements to arrive and build up the Allied advantage. In the west the forces of General Anderson came under attack in February at Faid Pass on the 14th and at Kasserine Pass on the 19th. The Allied forces retreated in disarray until heavy Allied reinforcements blunted the German advance on the 22nd.
General Harold Alexander arrived in Tunisia in late February to take command. The Germans attacked again in March, eastwards at Medenine on the 6th but were repulsed. Rommel counselled Hitler to allow a full retreat but was denied and on March 9 Rommel left Tunisia to be replaced by Jürgen von Arnim, who had to spread his forces over 100 miles of northern Tunisia.
These setbacks forced the Allies to consolidate their forces and develop their lines of communication and administration so that they could support a major attack. The 1st Army and the 8th Army then attacked the Germans. Hard fighting followed, but the Allies cut off the Germans from support by naval and air forces between Tunisia and Sicily. On May 7 the British took Tunis and American forces reached Bizerte, by May 13 the Axis forces in Tunisia had surrendered.
