My father's ship was patrolling off the cost of south vietnam. They were told that civilian Vietnamese fishing boats traveling east or west were fishing, whereas those going north or south were running ammunition or troops.

So one day they spotted a sailboat going south. The request permission to shell it. The permission was granted.

Dad thought it was quite funny, the shower of fish in the air when the shell detonated.

It never occured to me until many years later, to wonder about the crew aboard the fishing boat. It was quite common for entire families to live on their fishing boats for their whole lives.
