Nagasaki was not the primary target for the nuclear attack the United States launched against Japan on the morning of August 9, 1945. It had barely even made the list of potential targets for atomic bombings. Kokura was the primary target, and Nagasaki was the secondary target should weather conditions have prevented the attack on Kokura.
Conditions for the atomic bombing of Hiroshima, which occurred three days earlier, were perfect — sunny, clear skies, nothing to obscure the target. Not so on August 9 over Kokura. The city was obscured by clouds and smoke coming from a nearby town that had been, ironically enough, firebombed by the U.S. the day before. This was a big problem.
It was common during WWII for USAF (United States Air Force) ground crews to write out little messages on bombs meant to be dropped on the enemy. It was a sort of middle finger to the soldiers whom they blamed for there being a war in the first place. There are even stories of bomber crew members throwing trash out the plane as an extra bit of nastiness and rancor to go along with usual payload of high-explosive and incendiary ordinance.
French Corporal Jules André Peugeot was 21 years old when he was shot and killed by a German patrol. Although he was the first soldier to get shot in WWI, he ended up being the second person to die. The guy who shot Peugeot, German Lieutenant Albert Mayer, was the first person to actually die in WWI, with Peugeot himself succumbing to his wounds only a short while later. It all happened during a 13-person skirmish in the little French town of Joncherey, near the Swiss and German borders.
