Operation Compass was the first large Allied military operation of the Western Desert Campaign (1940–1943) during World War II. British and other Commonwealth forces attacked Italian forces in western Egypt and Cyrenaica, the eastern province of Libya, from December 1940 to February 1941, with great success. The Western Desert Force (Lieutenant-General Richard O'Connor) with about 30,000 men, advanced from Mersa Matruh in Egypt on a five-day raid against the Italian positions of the 10th Army (Marshal Rodolfo Graziani), which had about 150,000 men in fortified posts around Sidi Barrani and in Cyrenaica.
The 10th Army was swiftly defeated and the British prolonged the operation, to pursue the remnants of the 10th Army to Beda Fomm and El Agheila on the Gulf of Sirte. The British took 138,000 Italian and Libyan prisoners, hundreds of tanks and over 1,000 guns and aircraft for a loss of 1,900 men killed and wounded, about 10 percent of their infantry. The British were unable to continue beyond El Agheila, due to broken down and worn out vehicles and the diversion, beginning in March 1941, of the best-equipped units to the Greek Campaign in Operation Lustre.
