Mersa Matruh
Early in August, General Archibald Wavell was appointed Commander-in-Chief of the Middle East Command, and he sent reinforcements which had been sought by Wilson, initially the Indian 4th Infantry Division and advanced elements of 6th Australian Division and, as the buildup at Mersa Matruh continued, Richard O'Connor and his staff at 7th Infantry Division in Palestine were moved to Egypt to reinforce Wilson's command structure there. O'Connor's HQ, initially designated British 6th Infantry Division, was activated in November and became responsible for the troops at Mersa Matruh. It was redesignated Western Desert Force in June 1940.
