デスナ川
In September 1941, the German troops of XLVII. Armeekorps (mot.) (commander General of Panzer troops Joachim Lemelsen) advanced towards, and crossed the Desna River in the region southwest of Moscow. During the breakthrough attack, the German troops broke through the Bryansk Front on 30 September, during the operation to encircle the 50th Army. This resulted in the penetration of the Front's position between the 50th and 13th Armies.
