"Christmas in the Trenches" is by John McCutcheon. This is about the "Christmas Truce" that occurred during World War I. The Christmas truce (German: Weihnachtsfrieden; French: Trêve de Noël) was a series of widespread but unofficial ceasefires along the Western Front of World War I around Christmas 1914. In the week leading up to the holiday, French, German and British soldiers crossed trenches to exchange seasonal greetings and talk. In areas, men from both sides ventured into no man's land on Christmas Eve and Christmas Day to mingle and exchange food and souvenirs. There were joint burial ceremonies and prisoner swaps, while several meetings ended in carol-singing. Men played games of football with one another, giving one of the most memorable images of the truce. Peaceful behaviour was not ubiquitous; fighting continued in some sectors, while in others the sides settled on little more than arrangements to recover bodies. It was recorded by John McCutcheon and I learned it from there.
