Convoy PQ-18 20 miles South of Spitzbergen, Svalbard Island. At 4 AM, U-457 sets British tanker MV Atheltemplar on fire and the crew abandons ship (3 killed, 58 survivors picked up by British rescue ship Copeland and destroyer HMS Offa). MV Atheltemplar stays afloat and is finished off at 2.30 PM by U-408. Luftwaffe torpedo bombers from Banak attack again en masse but anti-aircraft fire from the convoy escorts and Sea Hurricane fighters from British carrier HMS Avenger break up the attacks (21 German aircraft shot down).

Stalingrad. Germans infantry again advance, meeting a counterattack by Soviet 62nd Army. At dawn, Luftwaffe aircraft bomb and strafe the Soviet troops who are pushed back onto Mamayev Kurgan, a Tartar burial mound 102 meters high (with dominating views of the city, also known as Hill 102). 2 miles south of Mamayev Kurgan, German 71st and 76th Divisions assault Central Station, which changes hands 4 times during the day and is eventually held by a NKVD rifle battalion. In the evening, Soviet 13th Guards Rifle Division (10,000 troops, ordered to the front by Stalin on hearing of the German progress yesterday) crosses the Volga in barges, tugs and rowing boats despite German shellfire and mortars. They go straight into combat (taking 30% casualties in 24 hours), preventing German troops cutting 62nd Army in two by reaching the Volga. There is a frost overnight, signaling the start of the Russian Winter.

The attack in the center makes some progress, although the Australian defenses hold out, but the flanking attack runs into 2/31st Battalion placed on the left in anticipation.
