Cause

In the final days of World War II in Europe, the Waffen-SS maintained control of Castle Itter in the Austrian Tyrol, where prominent French prisoners of war were held. As the Wehrmacht fragmented and Allied forces advanced, dissident German soldiers sought to protect the prisoners from fanatical SS units unwilling to surrender.

Event

On 5 May 1945, a combined force of US Army troops from the 23rd Tank Battalion, Wehrmacht soldiers under Major Josef Gangl, SS-Hauptsturmführer Kurt-Siegfried Schrader, and freed French prisoners jointly defended Castle Itter against an assault by the 17th SS Panzergrenadier Division until American infantry from the 142nd Regiment arrived to relieve them.

Consequence

The castle and its notable French captives were secured, and the attacking SS force was repulsed. The battle became historically notable as the only confirmed engagement in which Americans and Germans fought as allies during the war, and the only known instance of an active Waffen-SS officer joining the Allied side.
