Rommel, retreating westward from Libya, reached Tunisia. The Eighth Army (Lieutenant-General Bernard Montgomery) advancing from the east, stopped around Tripoli while the port was repaired to disembark reinforcements and build up the Allied advantage. In the west, the forces of the First Army came under attack at the end of January, were forced back from the Faïd Pass and suffered a reversal at the Battle of Sidi Bou Zid on 14–15 February. Axis forces pushed on to Sbeitla and then fought the Battle of Kasserine Pass on 19 February, where the US II Corps retreated in disarray until Allied reinforcements halted the Axis advance on 22 February. Fredendall was sacked and replaced by George Patton. General Sir Harold Alexander arrived in Tunisia in late February to take charge of the new 18th Army Group headquarters, which had been created to command the Eighth Army and the Allied forces already fighting in Tunisia. The Axis forces attacked eastward at the Battle of Medenine on 6 March but were easily repulsed by the Eighth Army. Rommel advised Hitler to allow a full retreat to a defensible line but was denied and on 9 March, Rommel left Tunisia to be replaced by Jürgen von Arnim, who had to spread his forces over of northern Tunisia. The setbacks at Kasserine forced the Allies to consolidate their forces, develop their lines of communication and administration before another offensive. The First and Eighth Armies attacked again in April. Hard fighting followed but the Allies cut off the Germans and Italians from support by naval and air forces between Tunisia and Sicily. On 6 May, as the culmination of Operation Vulcan, the British took Tunis and American forces reached Bizerte. By 13 May, the Axis forces in Tunisia had surrendered, opening the way for the Allied invasion of Sicily in July. Later influence Despite Operation Torch's role in the war and logistical success, it has been largely overlooked in many popular histories of the war and in general cultural influence. The Economist speculated that this was because French forces were the initial enemies of the landing, making for a difficult fit into the war's overall narrative in general histories. The operation was America's first armed deployment in the Arab world since the Barbary Wars and, according to The Economist, laid the foundations for America's postwar Middle East policy.
