I never knew that the Germans weren’t the first to make chemical gas for fighting. I was also really surprised that Hitler never used chemical gas on the battlefield, though I doubt he did so purely for humane reasons as he was, y’know, Hitler, so in my mind he most definitely had other motivations to not use gas attacks. On the topic of Hitler as a WWI soldier, I got interested and decided to look up some more about that. Here
Apparently, he was a very lucky soldier, in his first battle in the Bavarian Regiment, of the 3,000 men that were in the army, 2,500 survived and he happened to escape without a freaking scratch. Him being uninjured became a Thing, it was often that he would move a tiny bit then a shell would come down and kill everyone where he just was. Though, he did get wounded in his leg once which actually gave him a break from the Front and when he went back he got caught in a chlorine gas attack. He also painted whenever the fighting ceased (though he was apparently not good enough for art school, but that’s a whole other story.)
I found this cool video about Hitler almost dying on the battlefield here but I can’t quite confirm or deny it. From what I could find it seem’s to be that Hitler says it happened but some people think he made it up to show that this great war hero for the British saved him. I like to think it’s true because of the craziness of it.
I can’t confirm or deny this next thing, but I remember hearing that he cut his mustache like how we know it, so that it would fit into his gas mask during WWI but I couldn’t find sources.
If you know more on any of this I’d love to know.
