British gains in western desert
Tuesday, December 17, 1940 www.onwar.com
In North Africa... The British forces occupy Fort Capuzzo, Sollum and three other Italian positions near the Egypt-Libya border. The Italian garrisons of these places have withdrawn to the Bardia fortress.
In Washington... President Roosevelt gives a press conference outlining a scheme which he plans to introduce to bring further aid to Britain which he will call Lend-Lease. His argument is that if a neighbor’s house is on fire it is only sensible to lend him a hose to stop the fire spreading to your own house, and that it would be stupid to think of asking for payment in such circumstances.
In Vichy France... Laval, the former foreign minister, is released from prison after the German ambassador intervenes.
