The explosion blew open the hatches of No. 1 hold, put the Asdic and steering gear out of order and mortally injured two crewmen. The panic party abandoned the now slowly circling ship in two lifeboats but the submarine did not surface but fired a coup de gr√Ęce after about an hour that hit on port side amidships, causing her to slowly settle by the bow until sinking with a list to port at 1230 hours. 54 became missing and would be never found; 40 would be rescued. ww2dbase [Start of the Battle of the Atlantic | U-28 | CPC, HM]

At 2030 hours, French General Huntzinger called his government and informed that the Germans allowed no room for negotiations and demanded harsh terms; he was told to accept the German terms. Meanwhile, in southern France, the 32 Italian divisions deployed on the French border marched through the Little Saint Bernard Pass in the Alps and along the French Riviera; some of the Italians were met with a heavy snow storm and the latter halted by a very small group of French troops at Menton, which was about 5 miles from the border.
