We thought we were on the beach. Really we were hooked on an underwater obstacle. The doors went down and I very gallantly shouted 'Follow me!' and disappeared into eight feet of water. The fire was heavy and almost every man on my right was wounded or killed. I'd have been hit too but we found later that the machine gun that was doing the damage couldn't traverse that far. The man next to me was hit four or five times. I wasn't touched.
