The Russians had launched Operation Koltso or Ring on the 10th January which was aimed at ending the saga, but the Germans were still determined to fight on despite running out of ammunition, food and reinforcements. Zhukov’s plan was to punch a hole through the Kessel and to split the Stalingrad city area from those German units out on the Steppe. While they drove the Germans from the nose of the Kessel as we heard last episode, they stalled initially in the main aim of splitting up the pocket. This sounds counter-intuitive doesn’t it? After all, the Sixth Army was on the run eastwards towards the city and scenes of utter chaos were reported across the Steppe. Yet the Russians also found the going difficult at times as German defences were unbroken in some sectors. Many thousands of Germans and Romanians, Italians, Hungarians and other axis troops, fell to the Russians after the 10th January. 25 000 in all. But the number of German prisoners taken by the Russians was actually quite small, around 7 000, the rest of the divisions managed to withdraw to the East. However, other units had disappeared – the German 297th Infantry Division for example which was smashed beyond regrouping. By the early hours of the 11th January a message came through from the German High Command or OKH which demonstrated only too clearly how ignorant they were of conditions in the pocket. “Every possible step,” read the OKH coded message “were to be taken to prevent Pitomkin from falling into Russian hands..” On January 12th, a single Russian T-34 tank had somehow pierced the Pitomnik airfield defences and was ambling about around the runway, firing at will at medical tents, aircraft and men who were running in all directions. Before the Germans could recover, the tank disappeared into the morning mist. The airfield had no chance of fighting off a single tank, as soon as the Russians gathered their force once more to launch a proper assault, it was doomed. At 09h40 on the same day Army Group Radio reported that the enemy had broken through on a wide portion of the line. That night at 7pm Sixth Army reported to Manstein that “deep penetration east of Zybenko more than six kilometers wide. Our own losses were considerable. Resistance of the troops is diminishing quickly because of insufficient ammunition, extreme frost and a lack of coverage against heaviest enemy fire…” Missing from these reports were the number of desertions. German soldiers were running over to the other side in large numbers. Many officers in the field had now lost their will to lead and men had blankets over their heads as they slept in sentry posts. Worse, the mighty Wehrmacht had no tanks to fight off the T-34s.
