El Agheila. The Eighth Army was soon pushed back to Gazala west of Tobruk and at the Battle of Gazala in May 1942, the Axis pushed them all the way back to El Alamein, only from Alexandria. In 1942, the Royal Navy and Italian Navy were still disputing the Mediterranean but the British hold on Malta, and intelligence from Ultra, allowed the Royal Air Force to sink more Italian supply ships. Large quantities of supplies became available to the British from the United States and the supply situation of the Eighth Army eventually resolved. With the Eighth Army no longer constrained, the Axis were driven westwards from Egypt following the Second Battle of El Alamein in November 1942. Operation Torch In July 1942, the Allies discussed relatively small-scale amphibious operations to land in northern France during 1942 (Operation Sledgehammer, which was the forerunner of Operation Roundup, the main landings in 1943), but agreed that these operations were impractical and should be deferred. Instead it was agreed that landings would be made to secure the Vichy territories in North Africa (Morocco, Algeria and Tunisia) and then to thrust east to take the Axis forces in the Western Desert in their rear. An Allied occupation of the whole of the North African coast would open the Mediterranean to Allied shipping, releasing the huge capacity required to maintain supplies around the circuitous route via the Cape of Good Hope. On 8 November, Operation Torch landed Allied forces in Algeria (at Oran and Algiers) and Morocco (at Casablanca) with the intention that once Vichy forces in Algeria had capitulated, an advance would be made to Tunis some to the east. Prelude Allied plans Because of the nearness of Sicily to Tunisia, the Allies expected that the Axis would move to occupy the country as soon as they heard of the Torch landings. To forestall this, it would be necessary to occupy Tunisia as quickly as possible after the landings were made. However, there was a limit to how far east the Torch landings could be made because of the increasing proximity of Axis airfields in Sicily and Sardinia which at the end of October held 298 German and 574 Italian aircraft. Algiers was accordingly chosen for the most easterly landings. This would ensure the success of the initial landings in spite of uncertainty as to how the incumbent French forces would react.
