Operation Brevity [SEP] Introduction
Operation Brevity was a limited offensive conducted in mid-May 1941, during the Western Desert Campaign of the Second World War. Conceived by the commander-in-chief of the British Middle East Command, General Archibald Wavell, Brevity was intended to be a rapid blow against weak Axis front-line forces in the Sollum–Capuzzo–Bardia area of the border between Egypt and Libya. Although the operation got off to a promising start, throwing the Axis high command into confusion, most of its early gains were lost to local counter-attacks, and with German reinforcements being rushed to the front the operation was called off after one day.
