I run a blog on tumblr as Bucky Barnes, and I'm often asked to tell stories from the 'good old days,' and bar fights have come up a couple times. Given that it's Marvel-universe, I'm not super concerned with getting every little detail right, but I would prefer to use historically correct information when possible. I ran some searches in google on bar fights during the war (1940s bar fight, pub fight, WWII bar fight), but there's a video someone made of WWII as a bar fight that makes it pretty difficult to find historically relevant articles. I did find some interesting stuff about women in America stepping in the fill the shoes of absent male bartenders during the war, but I'm more interested in things closer to the eastern front. So what I'd like to know is information in the following veins: how often did bar fights occur with soldiers on leave in Europe? How severe were sanctions for such fights? Were they common? Were they typically between same-country same-branch military members, or would it be likelier to happen between military and civilians, or different military members from allied countries?
I know there's probably not a ton of data on this, but even just a good impression of what happened in a few specific occasions would be helpful. This isn't a super pressing research topic--it's mostly to sate my own curiosity and keep from tiny misinformations in my writing, so unless it strikes your fancy, please don't feel the need to go out of your way for this issue. Thanks!
