The force in the Middle East was clearly too small, reinforcement by sea was a 14,000-mile trip that required three months to complete, and reinforcement via the Western Mediterranean was hardly practical due to the ranges involved, which only bombers could achieve. Thus, an alternate reinforcement route began to be pioneered via Takoradi in the Gold Coast, from which new aircraft were received by sea, assembled, test flown, and ferried across Africa to Khartoum, a route first pioneered by Air Vice-Marshal Arthur Coningham in 1925. By this and other means, by the end of November 1940 the RAF in Egypt had been bolstered by No. 73 and No. 274 Squadrons with Hurricanes and No. 37 and No. 38 Squadrons with Vickers Wellingtons, as well as several South African Air Force squadrons, ready for the beginning of Operation Compass. During Compass, "the squadrons of Hurricanes, Lysanders, and Blenheims … strove hard to keep pace the ground forces, often landing after a combat sortie at a more advanced strip than from which they had set out."
