So at some point while he was over there, his outfit was under attack and an explosion went off from a shell or a grenade or something. And my grandfather was helping tend to the wounded, and they get this guy who is just covered on blood. Like, soaked, head to toe. And they think "Ohhhhh noooooo, I don't think we're gonna be able to save this guy." But they start cleaning him up anyway, to see what they can do. And cleaning him up, and cleaning him up, and there's nothing wrong, and they keep cleaning, and keep cleaning, and eventually they find that the only injury he has is a cut on his head from a piece of shrapnel, and all he needs is a couple stitches.
The moral of the story being, scalp wounds bleed a lot.
Anyway, a salute to all the veterans I know (and those I don't). War is stupid and horrible but sometimes unavoidable, and I'm thankful to everyone who's helped to keep the nastiness that drives it beaten down.
