Michael Wittman was the CO of the 2nd company of Pz Abt 101 at the time of the Villers Bocage battle. As such his personal tank would have probably been turret number 205. His company had just finished a long drive to the front the previous day and all but five of his tanks had broken down on the way. This included his own, so he had comandeered another tank to command. This also broke down as he drove off to engage the enemy, as did the second one he tried. The third Tiger he used actually worked and this was the one he used to wreak carnage on the British column before it was knocked out and he abandoned it. After the subsequent battle for the town a British officer destroyed all the abandoned Tigers in the town by igniting petrol soaked blankets in the crew compartment before retreating. So no one really knows what turret number tank he used that day, although there's whole threads on the issue in some forums.
Later Wittman was promoted to command the whole Battalion. As CO he was given the lead tank number 007 and was in this tank when he was killed. He and three other Tigers were advancing to engage a British column. Wittman moved out to the left near an abandoned monastery and the other Tigers advanced up the road itself. What he didn't know is that the Allies had already advanced during the night. Wittman was probably taken out at point blank range by Canadian Shermans hiding behind the high monastery wall, they'd previously blown holes through it to shoot through. His other three tanks were taken out in four shots by a single British Firefly hiding in the woods to the right of the road.
