Just before D-Day Landings there were lots of Americans being prepared at Weymouth where we lived.
When I came back from Hong Kong my brother's ship used us as a dummy target.
We were tailed by a U-boat for 3 days when we were going out to India. We couldn't identify the U-boat and our skipper prepared us that it might attack but after 3 days it just disappeared and we never did identify it. We always assumed it was one of ours just checking us.
