Looks kind of strange, doesn’t it? The way the ground ripples like that?
This is Verdun today. During World War I, seven hundred thousand people died in battle here, with another three hundred thousand dead from injuries, over the course of a ten month siege by Germany upon the French. Forty million artillery shells pounded the countryside, sculpting it into these shapes. The Battle of Verdun is widely known as France’s Stalingrad. Your mental image of WWI, with the trenches, and the smoke, and the screaming, and the artillery fire, and the hellish meatgrinder of a battle that never ended or relented, comes, in large part, from Verdun.
The French held the line. The Germans were forced to withdraw, leaving nearly half a million of their own dead behind.
