The Royal Navy inflicted a major setback upon the Italian Royal Navy during the Battle of Taranto on the night of 12/13 November. After assembling enough forces the British launched a counter-attack upon the Italians in Egypt. Operation Compass drove the Italians out of Egypt and resulted in the destruction of the Italian 10th Army in February 1941. Following this success, British forces adopted a defensive position in North Africa and redeployed most troops to Greece in Operation Lustre, leaving a weak force garrisoning the gains made from Operation Compass. In March, the Battle of Kufra ended with the Italians losing the desert oasis of Kufra—a vital link between Italian east and north Africa—which was located in south-eastern Libya.
