Now...everybody's favorite... the "haversack" type shoulder bag.... Despite the cries that ONLY the military ever used such a thing, I do have 18th century images of genuine non-military people with haversack-type shoulder bags.
I don't dispute that bags similar in shape to the military haversack were used..., what I STRONGLY object to..., is everybody who speaks English, who has a single strap pack with a top flap secured by one or more buttons, referring to that single strap bag with a button-secured flap...as a "haversack"! When what I've found is that term in an era when terminology was often loose..., that term in English seems to be exclusively used for the name of the marked, military, ration bag, that a civilian would not have unless that person was somehow attached as part of the army.
I've found a great many references to the "haversack" and they were all referencing the military, ration bag.
Sorry..., I'm back now....
