Actually it was the "Phillipine Insurection". The Spanish American war was already over, and Spain had ceded the Phillipines to us. We were fighting Moro (Muslim) rebels.
Correct. The Moro uprising, with hyped up muzzies who could not be stopped with the S&W 38 Double Actions, nice as they were. So they went temporarily to a 45 cal revolver then to Brownings semi-auto and... history.
Actually the war that gave birth to the .45 Auto was the Moro War, which was separate from the Philippine Insurrection, although the two wars are often confused. The Moro War, which lasted from 1902 to 1917 was arguably America’s longest war, yet for some reason it has been largely forgotten. It pitted US servicemen against Muslim tribesmen known as Moros and was fought on the island of Mindanao. The Moros fought with fanaticism, so we needed a firearm with stopping power.
