The entry in their War Diary does not say that. You could at a stretch take it to mean they destroyed it but the evidence (the photos) show it was not destroyed. The photos show a Tiger wrecked by its own internal charges . It is not a Tiger that has been demolished by engineers. It could be that it was knocked out first and then had to be abandoned and they blew up but for sure it was the Germans who finished off that Tiger themselves. All types of tank were blown up to make them easier to remove but they would be stuffed with HE. One of the Tigers at Villers was filled with lifted mines and then exploded. The evidence is not enough to be definitive. All the accounts contradict each other in some of the details.
