The 1941 Siege of Tobruk took place in which North African country?

The Siege of Tobruk lasted for 241 days in 1941, after Axis forces advanced through Cyrenaica from El Agheila in Operation Sonnenblume against Allied forces in Libya, during the Western Desert Campaign (1940–1943) of the Second World War. In late 1940, the Allies had defeated the Italian 10th Army during Operation Compass (9 December 1940 – 9 February 1941) and trapped the remnants at Beda Fomm. During early 1941, much of the Western Desert Force (WDF) was sent to the Greek and Syrian campaigns. As German troops and Italian reinforcements reached Libya, only a skeleton Allied force remained, short of equipment and supplies.

The siege diverted Axis troops from the frontier and the Tobruk garrison repulsed several Axis attacks. The port was frequently bombarded by artillery, dive-bombers and medium bombers, as the RAF flew defensive sorties from airfields far away in Egypt. Allied naval forces, such as the British Mediterranean Fleet (including the Inshore Squadron) ran the blockade, carrying reinforcements and supplies in and wounded and prisoners out. On 27 November, Tobruk was relieved by the Eighth Army (which controlled British and other Allied ground forces in the Western Desert from September 1941) in Operation Crusader.
