On the Eastern Front... In the Caucasus, Army Group A (Kleist) is withdrawing under pressure. Army Group Don (Manstein) continues to defend Army Group A’s line of communication around Rostov. In the north, the Soviets attempt to widen the supply route to Leningrad which is presently no wider than 6 miles and exposed to German fire. The area becomes known as the “corridor of death.” Meanwhile, at Stalingrad the German 6th Army pocket has been reduced to about 250 square miles, about half the area it controlled five days ago.
In the Solomon Islands... On Guadalcanal, American forces advance west and southwest of their perimeter. Japanese positions overlooking the upper part of the Matanikau River are captured.
In New Guinea... In converging attacks near Sanananda, the US 163rd Infantry Regiment and the Australian 18th Brigade are making progress.
In Morocco... The Casablanca Conference. The Anglo-American strategy discussions continue.
