Awarded for actions during Operation Barbarossa. On 7/9/1941 Ziemer commanded the lead platoon of his regiment during its advance against a river near Molwotizky. Upon spotting an intact 8-ton bridge he burst forth with his platoon and seized it before it was blown up. He then held it against superior Soviet forces until reinforcements could be brought up. Through his actions his regiment was able to move across the river against enemy forces on the same day near Welikuscha and crushed them.
