During April 1942, in the area west of Kaluga, a freshly arrived Soviet rifle division launched an advance that got to within 3 km of the the Roslawl—Juchnow road. In response Oberst Källner took command of the first friendly battalion that arrived on the scene, retook those villages that had been lost in a counterattack and pushed the enemy away far enough so that they could no longer take the road under fire. In doing this the enemy breakthrough attempt was also brought to a halt. For this action Källner would receive the Knight’s Cross.
