turned into a disaster and only 28 of the 88 tanks committed returned to their start line. The 6th Panzer Division signalled that "a strong enemy force was making a breakthrough" which caused alarm . Kleist ordered the 6th Panzer Division and 8th Panzer Division eastwards to counter the Allied breakthrough. In the aftermath the Germans treated the Battle of Arras as a minor defeat for the Allies. Casualties Rommel noted in his diary that his division had lost killed, and missing and captured, as many as the first four days of operations, which included the Meuse crossing, although 90 of the missing returned to their units.
