The Christmas truce 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 some 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.
A Christmas truce memorial was unveiled in Frelinghien, France, on 11 November 2008. Also on that day, at the spot where, on Christmas Day 1914, their regimental ancestors came out from their trenches to play football, men from the 1st Battalion, The Royal Welch Fusiliers played a football match with the German Battalion 371. The Germans won 2–1.
