Seriously humming bird, there might have been a general who did that, and everyone would agree that Australia did its part to rid the world of the Nazis and the expanding Japanese Empire, but come on. Are you an idiot? Anyway, I don't know if it was the hornet, but it sounds right, but the first U.S. air attack on the Japanese mainland was Doolittle's raid. I think they were eB-25 Mitchell's stripped down to be flying gas cans that hit Japan and ditched in China in like May of 1942. It wasn't meant to be an extremely damaging campaign but simply to show the Japanese that they were vulnerable after Pearl Harbor. Yes, the Enola Gay bombed Japan, but that was in August of 1945.
