On 6 February 1941, Rommel was appointed commander of the new Afrika Korps ("Deutsches Afrika Korps"; DAK), consisting of the 5th Light Division (later renamed 21st Panzer Division) and of the 15th Panzer Division. He was promoted to "Generalleutnant" three days later and flew to Tripoli on 12 February. The DAK had been sent to Libya in Operation Sonnenblume to support Italian troops who had been roundly defeated by British Commonwealth forces in Operation Compass. His efforts in the Western Desert Campaign earned Rommel the nickname the "Desert Fox" from British journalists. Allied troops in Africa were commanded by General Archibald Wavell, Commander-in-Chief, Middle East Command.
