After the Red Army counterattacked and re-took Rostov in November 1941, the 100th Jäger Division marched south to the front line on the Mius River on 22 November. Temperatures dropped as low as -18C, and the regiment had no winter clothing. The regiment's units, still divided among the other regiments of the division, dug in alongside the Slovak Mobile Brigade and SS-Division "Wiking". In mid-January 1942, the 100th Light Infantry Division was deployed to the Stalino area to assist in fighting off a Soviet cavalry corps that had broken through the front line. Through some heavy fighting along the line of the Samara River, the division held on through the winter.
