I had an uncle who might have been the luckiest man in history.
He joined the Navy at 17, & was assigned to some minor ship in Pearl Harbor as a cook's helper. On about Dec 5th, 1941, he and a couple others were assigned TDY on the Arizona. The morning of Dec 7th, he was on the other side of the island picking up a load of fruit & vegetables when the attack happened. On the way back, they were pressed into service humping ammo for an anti-aircraft battery. By the time they got back to the harbor, it was all over.
He served on a couple of minor ships throughout the war, and at some point went home on leave for his father's funeral. He got orders to report to his new ship, but as he traveled across the country, the train broke down & he was a day late to sail with his new ship, which left without him. He was assigned to another minor ship and served there the rest of the war.
The ship he missed embarking on was the USS Indianapolis, on it's way to take the bomb to Tinian Delady.
