Möbus wounded. On 19 November 1942 the Red Army began Operation Uranus, an encirclement operation which encircled the German 6th army and several other Axis armies in Stalingrad. The chaos of the evacuation of Stalingrad, partial elements of II gruppe, either some or all of 6 staffel under the command of Oberleutnant Heinz Jungclausen operated from inside the pocket until December. This unit flew 200 sorties from within Stalingrad. On 1 January 1943 no operational aircraft appeared in the record. After the Raid on Tatsinskaya, the airfield itself fell on 7 January and the group suffered heavy losses in ground personnel. The solitary remaining Ju 87 in 4 staffel was blown up to prevent its capture. StG 2 attempted to provide support for the Romanian 3rd Army and Romanian 4th Army on 21 November, contributing 141 dive bombing missions which cost it five Ju 87s. One group based at Tusov airfield 20 miles west of Kalach, escaped tanks of the 26th Soviet Tank Corps by flying away though other units were caught. Stab., I., and II./StG 2 reported 40 aircraft destroyed—17 to enemy action, 11 to other causes, six damaged and under repair and six sent to other units. The remainder are not specified in the Quartermaster records or StG 2's war diary. At least 25 Ju 87s were lost or severely damaged in November 1942. On 24 November 1942 another significant loss was Hauptmann Joachim Langbehn, a veteran of 400 combat missions. He was posthumously awarded the Knight's Cross. A notable success occurred when Rudel led 1./StG 2 into combat against elements of the 5th Tank Army, 8th Cavalry Corps reached the airfield at Oblivskaya. The last tank was destroyed on the airfield perimeter. I./StG 2 was trapped inside at Karpovka airfield until the site was overrun by Soviet tanks. The group's ground personnel were utilised as infantry. Flying personnel relocated to Morosovskaya, north east of Rostov-on-Don to continue operations in appalling weather conditions. The airfield was abandoned in the face of Soviet advances and five Ju 87s were destroyed by the group. It reported 44 Ju 87s on strength three days earlier and the group relocated to Nikolayev. 700 ground crew from StG 2 were left behind in Stalingrad. They formed an improvised Luftwaffe field battalion and were lost in the destruction of the pocket. The group supported the failed relief effort, Operation Winter Storm. By 25 December
