> one gallon per man per day No it wasn't. There was never a time that a whole gallon per day was a normal rum ration. It was a gallon of beer, later a half pint of rum.

Over time it was reduced until it turned into basically a shot, and then even that was stopped. https://en.wikipedia.org/wiki/Rum_ration https://en.wikipedia.org/wiki/Rum_ration
