"LITTLE BOY" THEN "FAT MAN" AND IT WAS OVER!

I have been away from my desk for a time and have just completed the four book, wonderfully researched, history of the Pacific war written by James D. Hornfischer.  Those who served there or have an interest in history will do well reading his books.
It was the summer of 1945 and the war in Europe had been won.  Plans were underway for the invasion of Japan with expectations of up to a million and a half U.S. casualties.  There was a way to avoid such numbers.  Saipan and Tinian (three miles it's neighbor) had been taken by Marines, at great price, and airstrips were built to handle B-29 bombers, new, four motor, pressurized, long distance behemoths, expected to clobber the cities of Japan.
The U.S.S. Indianapolis sailed into Tinian with a cargo even the Captain did not know what.  It was after delivering his package that She was sunk by a Jap torpedoe with the loss of 2/3 of Her crew.
I had a friend who was stationed on Tinian and helped load that cargo "Little Boy" on Paul Tibbet's "Enola Gay" (named after his mother) destined for Hirosima
Tibbets and crew had been training for this for months.  He had gone to Omaha and personally chose the B-29 he wanted.  There was no room for error.  The "gun" that fired the "bullet" of U-235 into the core of the bomb was not inserted into the firing chamber until airborne, reason?  The bomber was noted for crashing on takeoff.  The engines were not reliable and engine failure was common.
After Hiroshima, and no surrender plea from the Emperor, the "Fat Man" was dropped three days later, August 9, on  Nagasaki.  
The Emperor Hirohito never used the word "surrender" but instead spoke the word "capitulated".  It amounted to the same thing, the war was over.  No bloody invasion was needed.
September 2, 1945 the papers were signed on board the U.S.S.Missouri--The war was over!
It is worth noting here that six of the crew of twelve on the "Enola Gay" were enlisted men from PFC to Staff Sgt........Medicineman!
