Operation Crusader was a military operation by the British Eighth Army between 18 November–30 December 1941 during the Second World War. The operation relieved the 1941 Siege of Tobruk. The Eighth Army's initial plan to destroy the Axis armoured force before advancing its infantry came apart when, after a number of inconclusive engagements, the British 7th Armoured Division were heavily defeated by the Afrika Korps at Sidi Rezegh.
