Having just concluded Operation Uranus around Stalingrad, the Red Army launched Operation Mars near the Rzhev salient outside of Moscow.
Operation Mars remains a controversial offensive, as the Soviets later claimed it was a diversion designed to tie down German forces in the north so that they could not be redeployed to the south. This view has been taken by famed student of the Red Army, Anthony Beever. Noted historian David Glanz, however, disagrees, and I frankly feel that Glanz has the better side of the argument.
It should be noted that the offensive was supposedly the subject of a radio false information campaign by the Soviets, something they were very good at, designed to draw attention to it prior to its commencement. The overall problem is that, as a diversion, if it was one, it was a big one which wasn't skillfully executed, which would be odd as its success, diversion or not, should have been something sought by the Soviets.
The Soviet offensive would ultimately fail, which may provide the reason for its having been claimed as a diversion. If it was a diversion, it was a massive one, involving over 700,000 troops. Notably, in Mars the Red Army was encountering German troops, who fought stubbornly from its onset, rather than the forces of Germany's Eastern Front allies. Additionally, the offensive started after Uranus had concluded, whereas if it were a diversion it would seem more likely that it would have commenced simultaneously.
As with Stalingrad, the German forces were subject to a Hitler no retreat order. Hitler had issued a similar order the prior winter, which had proven instrumental in stabilizing the front. The strategic situation had changed since then, however, and while it worked in this instance, it was costly. The Germans took 40,000 casualties, small compared to the outsized 335,000 casualties the Red Army took, but the losses would not be made up by the German 9th Army by the following spring and therefore made it less effective in resumed offensive operations that year.
The Washington Post ran an article with the headline:
Two Million Jews Slain
This was the written report on the live announcement by Rabbi Stephen Wise announcement of the prior day. It did not make the front page.
The Luftwaffe began to fly supply missions into Stalingrad.
At Meijez el Bab British forces made a disastrous attack on the town, which was defended by German paratroopers of the Luftwaffe's 5th Fallschirmjager Regiment. The unit had been in North Africa since the summer, at which point it became part of the Afrika Korps. It's deployment to Tunisia had been by plane, but they had not made a combat drop.
Medjez al Bab is an ancient city and was the site of a prior battle, the Battle of Bagradas River in 536 at which Eastern Roman Empire forces under Belisarius fought rebel forces under Stotzas.
British SOE operatives and Greek resistance fighters raided the Gorgopotamos viaduct in Operation Harling.
