My Dad too, they had orders to get ready to assault the mainland before the A-Bomb order was given.
My father was in the battle of Okinawa and they would’ve been one of the groups used for the invasion. Men wept when they heard because they knew they were going to live.
My father was getting ready to attending landing craft school before the A-bomb was dropped on Japan. He was in the Coast Guard and was going to be one of the guys who operated the landing crafts.
According to one estimate I saw, a conventional invasion of Japan would have cost 5 - 6 million Japanese lives and one million American casualties.
