One of Many Deaths

Summary
When Hilter was in the trenches in WWI in OTL a shell hit the dugout he was in, he is the only survivor. POD, he is stood slightly further fowards, and a piece of shrapnel slashes his neck, killing him. I don't know enough about the political situation in Germany when Hitler would have come to power, so if anyone wants to they can write what they think would happen in Germany.
