A Look Back at the airlift into the Demyansk Pocket:
The encirclement began as the Demyansk Offensive Operation, the first phase being carried out from 7 January-20 May 1942 on the initiative of General Lieutenant Pavel Kurochkin, commander of Northwestern Front. The intention was to sever the link between the German Demyansk positions, and the Staraya Russa railway that formed the lines of communication of the German 16. Armee. However, owing to the very difficult wooded and swampy terrain, and heavy snow cover, the initial advance by the Front was very modest against stubborn opposition. On 8 January, a new offensive called the Rzhev-Vyazma Strategic Offensive Operation started. This incorporated the previous Front's planning into the Toropets-Kholm Offensive Operation between 9 January and 6 February 1942 which formed the southern pincer of the attack that, beginning the second phase of the northern pincer Demyansk Offensive Operation between 7 January and 20 May, which encircled the German 16th Army's (Generaloberst Ernst Busch) IInd, and parts of the Xth Army Corps (General der Artillerie Christian Hansen) during winter 1941/1942.
Trapped in the pocket were the 12th, 30th, 32nd, 123rd and 290th infantry divisions, and the SS-Division Totenkopf, as well as RAD, Police, Todt organization and other auxiliary units, for a total of about 90,000 German troops and around 10,000 auxiliaries. Their commander was General der Infanterie Walter Graf von Brockdorff-Ahlefeldt, commander of the IInd Army Corps....
After being assured that the pocket could be supplied with its daily requirement of 270 short tons (240 t) of supplies by Luftflotte 1, Hitler ordered that the surrounded divisions hold their positions until relieved. The pocket contained two fairly capable airfields at Demyansk and Peski. From the middle of February, the weather improved significantly, and while there was still considerable snow on the ground at this time, resupply operations were generally very successful due to weakness of the Red Air Forces in the area. However the operation did use up all of the Luftwaffe's transport capability, as well as elements of their bomber force.
The Northwestern Front grew increasingly desperate to wipe out the pocket, and over the winter and spring, launched a number of assaults on the "Ramushevo corridor" that formed the tenuous link between Demyansk and Staraya Russa through the Ramushevo village that were repeatedly repulsed. In total, five Soviet Armies composed of 18 rifle divisions and three brigades were tied up for four months....
Between the forming of the pocket in early February to the virtual abandonment of Demyansk in May, the two pockets (including Kholm) received 65,000 short tons (59,000 t) of supplies (both through ground and aerial delivery), 31,000 replacement troops, and 36,000 wounded were evacuated. However, the cost was significant. The Luftwaffe lost 265 aircraft, including 106 Junkers Ju 52, 17 Heinkel He 111 and two Junkers Ju 86 aircraft. In addition, 387 airmen were lost....
The success of the Luftwaffe convinced Reichsmarschall Hermann Göring and Hitler that they could conduct effective airlift operations on the Eastern front. Göring later proposed a similar "solution" to supply the 6. Armee when it was surrounded in Stalingrad. In theory, the outcome could be equally advantageous; with the 6. Armee trapped, but still in fighting condition, the Soviet army would have to use up much of its strength to keep the pocket contained. This could allow other German forces to re-group and mount a counterattack. However, the scale of the forces trapped in the two operations differed greatly. While a single corps (about ⅓ of an army) with about six divisions was encircled in Demyansk, in Stalingrad, an entire and greatly reinforced army was trapped. Whereas the Demyansk and Kholm pockets together needed around 265 t (292 short tons) of supplies per day, the 6. Armee required an estimated daily minimum of 800 t (880 short tons), delivered over a much-longer distance and faced by a much better organised Red Air Force. The air transport force had already suffered heavy losses, and was much further away from good infrastructure. The Luftwaffe simply did not have the resources needed to supply Stalingrad.
