13. 8 8 Nov 1942: Operation Torch. Knowing that they are not yet strong enough for a direct assault into Europe, but realizing they must attack somewhere, the Allied Combined Chiefs of Staff decided to attack North Africa to assist the British 8th Army in destroying the German/Italian Forces that were fighting in Libya. At three landing sights, the Allies landed in Morocco and Algeria and quickly defeat the Vichy forces there. Eastern Task Force Center Task Force Western Task Force

14. 8 10 Nov 1942: Germans occupied Southern France and Corsica as the Vichy government began to topple (due to defections in N. Africa).

15. 1 8 November 1942 – The allies advanced toward Tunisia to seize critical supply ports. However, the Germans rushed troops into Tunisia from Italy/Sicily and form the 5th Panzer Army. The Germans successfully halted the Allied advance just short of their goal. The British 1st Army was now forced to go on the defense and wait for supplies and reinforcements to arrive from their very long supply lines, as well as wait for better weather. A French and American Corps occupied positions to the south of the main British Corps. In early February, Panzer Army Afrika (Rommel) arrived in Tunisia after being driven from Egypt by the 8th Army.
