On December 30th, 1944 Major Mickley, (Kommandeur II. Panzergrenadier-Bataillon/Führer-Begleit-Brigade) died from a serious abdominal injury caused by shrapnel during an assault on the town of Sibret, Belgium. He was posthumously promoted to Oberstleutnant.
On the 21.07.1944 Hauptmann Mickley and his Bataillon were fighting in a retreat battle west of Ostrow. Here they became encircled by the enemy, and more than that lacked proper AT weapons and were almost out of ammunition. The only retreat route was over a bridge occupied by enemy tanks. With his 200 combat capable troops and a great number of wounded, he used the cover of darkness to fall in alongside a Soviet march column that was moving towards the bridge. Just before reaching the crossing the Germans dropped the ruse and went into the attack, with Mickley at the head of the forward Kompanie. Utilizing the enemy’s confusion they managed to storm the bridge. Thereafter Mickley and his troops were able to get the whole battalion across, including all the wounded and vehicles, before finally destroying the bridge after all friendly forces had passed over.
For managing to extract his entire battalion from the jaws of annihilation in such an outstanding manner Mickley would receive the Oakleaves to his Knight’s Cross.
