I think this incident occurred in February because it was very muddy. We were attacked by 3 or 4 Tiger tanks. The lieutenant who was the forward observer must have been put out of action because the first we saw of them, they were no more than 500 yards away. We loaded up with white phosphorus, depressed the guns, and started firing. We got one tank almost immediately, a hit right in the tread, but the others kept coming. We kept firing, but they went right over and past us. I hid in a gun emplacement as they went by. Apparently they had some other mission and just left us.
