A well-known historical fact. Heartwarming and sad at the same time.

British and German soldiers hanging out with each other at Ploegsteert during the Christmas Truce, circa. December 24, 1914.
The famous Christmas Truce began along the Western Front. German soldiers at St. Yves in Flanders decorated their lines with candles and Christmas trees, following it up by singing Christmas carols. The British soldiers responded by singing carols of their own and soon soldiers from both sides began venturing out into no man’s land. This culminated into a full out Christmas Truce between the British and Germans, who all met each other face to face in no man’s land. The soldiers exchanged gifts such as alcohol, foods, tobacco and souvenirs. They exchanged pictures of their families, took photographs with each other, held joint burial ceremonies for their fallen soldiers, and small-scale football (soccer) matches were played.
