Input: Question: What regiment was the commander of the Tiger tank that cut off the Rifle Brigade from? Passage:The regiment landed in Normandy on 7 June 1944, the day after D-Day. During the Battle of Normandy, 4th CLY served as part of the 7th Armoured Division. On 13 June, they led the advance of 22nd Armoured Brigade with A Company of 1st Battalion, Rifle Brigade (Prince Consort's Own) by road from Villers-Bocage and were ambushed by a detachment comprising five Tiger tanks. One of the Tigers, commanded by SS-Obersturmführer Michael Wittmann, cut in behind the lead squadron, cutting them off and destroying the soft-skinned vehicles of the Rifle Brigade before running into the Sharpshooters Headquarters Troop and accompanying artillery observation tanks. Wittmann is credited with up to ten of the kills before his tank was immobilised and he escaped on foot. The cut-off squadron was later forced to surrender after the arrival of a further ten Tiger tanks. These Tigers, with elements of Panzer-Lehr-Division and 2nd Panzer Division, then counter-attacked the British in the town, but lost up to eight Tigers and two Panzer IVs before the British withdrew. 4th CLY lost its commander, Lieutenant Colonel The Viscount Cranley, and second-in-command; "A" Squadron was destroyed. 4 CLY's losses for the day amounted to 20 Cromwells, four Fireflys, three Humber Scout Cars, three Stuarts and a half track.
