Check your history, Pershing ran into the Moros while fighting in the Philippines during Spanish American war (1898) They were muslim, you still hear about muslim rebels causing trouble in Philippines, taking hostages and killing.
That run in was why we developed the 1911 pistol .45 ACP the
current .38 pistol was ineffective, Army reissued old SAA Colt 45 pistol (cowboy type single action revolvers) as a stopgap
Yeah, thanks, I’m just going on my cursory knowledge of history. Didn’t think about Filipinos, although just how many were Moslem?
Anyway, it looks like the premise was debunked. No evidence of that particular story, and only 1 personal account of something kinda similar.
