In November 1942, Britain and America launched Operation TORCH, the ambitious invasion of French North Africa.To convey 70,000 troops and their equipment required 600 merchant ships crossing the U-boat infested North Atlantic. The need for their protection meant withdrawing escorts from the routine convoys. Amongst those left without adequate defence were RB 1 and SC 107, both eastbound from America, and SL 125, northbound from Freetown. All three were at sea at the same time as the TORCH convoys.
