World War 2,North Africa, Libya, Tobruk, 1941

Tobruk is a Mediterranean port with an excellent deep-water harbour. During World War 2, as a supply hub, it was important to both Allied and Axis forces. In January 1941, it was captured from the Italians by General Wavell's forces which included the Australian 6 Division. When Rommel drove across Cyrenaica towards Suez in April 1941, it was essential that Tobruk be held. The main infantry component of the defending force was the Australian 9th Division and 18 Brigade from 7th Division. Tobruk was surrounded and besieged from 11 April to 10 December 1941, when the Axis forces were driven back.
Many of the Australian defenders had been relieved during August and September 1941 but 2/13 Battalion remained throughout the siege.
