Operation Greif was a special false flag operation commanded by Waffen-SS commando Otto Skorzeny during the Battle of the Bulge. The operation was the brainchild of Adolf Hitler, and its purpose was to capture one or more of the bridges over the Meuse river before they could be destroyed. German soldiers, wearing captured British & US Army uniforms and using captured vehicles were to cause confusion in the rear of the Allied lines. A lack of vehicles, uniforms and equipment limited the operation and it never achieved its original aim of securing the Meuse bridges.
