On Christmas Day, 1914, in the first year of World War I, German, British, and French soldiers disobeyed their superiors and fraternized with "the enemy" along two-thirds of the Western Front. German troops held Christmas trees up out of the trenches with signs, "Merry Christmas."
"You no shoot, we no shoot."
Thousands of troops streamed across a no-man's land strewn with rotting corpses.
They sang Chrismas carols, exchanged photographs of loved ones back home, shared rations, played football, even roasted some pigs.
Soldiers embraced men they had been trying to kill a few short hours before.
They agreed to warn each other if the top brass forced them to fire their weapons, and to aim high. A shudder ran through the high command on either side. Here was disaster in the making: soldiers declaring their brotherhood with each other and refusing to fight. Generals on both sides declared this spontaneous peacemaking to be treasonous and subject to court martial.
By March, 1915 the fraternization movement had been eradicated and the killing machine put back in full operation. By the time of the armistice in 1918, fifteen million would be slaughtered.
