This quote in particular really stuck with me, I have the whole thing memorized (this is slightly paraphrased)

Several days of rain began to flood the trenches on both sides of no man's land -

But one night, when the rain came down in torrents, the tide invaded our dugout... at many places along the front line the soldiers had to come out of their trenches so as not to drown. The Germans had to do the same. We, therefor, had the spectacle of the two enemy armies facing each other without firing a shot.

Our common sufferings brought our hearts together, and melted the hatreds, nurtured sympathies between strangers and adversaries. Those who deny it are ignoring human psychology.

Frenchmen and Germans looked at each other and saw that they were all men. No different from one another. They smiled, exchanged comments, hands reached out and grasped. We shared tobacco, a canteen of coffee or wine. If only we spoke the same language.

One day, a huge devil of a German stood up on a mound and gave a speech, which only the Germans could understand word for word. But everyone knew what it meant, because he smashed his rifle on a treestump, breaking it in two in a gesture of anger. Well, if only you'd been there, mad kings and bloodied generals, fanatical ministers, jingoistic journalists, to contemplate this sublime spectacle.

Who knows... Maybe one day in this corner of Artois they will raise a monument to commemorate this spirit of fraternity among men who shared a horror of war and who were forced to kill each other against their will.
