At the head of the retreating column from 2nd SS Panzer Division at the crossroads near Notre-Dame-de-Cenilly was this 150mm Hummel self-propelled gun named “Clausewitz” and SdKfz 251 half-track, followed by about 90 other vehicles and 2,500 Waffen-SS troops. It was finally stopped around midnight at a roadblock of Co. I, 41st Armoured Inf. Regt., 2nd Armoured Div when the driver and gunner were shot at close range. The ensuing traffic jam along the hedgerow-lined road left the remainder of the retreating column exposed to American fire, and a savage night-time battle began in which the column was largely destroyed.
