a christmas truce

That's right. During World War I, the Christmas truce of 1914 was an informal and unofficial cease-fire between the Allied Forces and the Central Powers along the Western Front of World War I during Christmas 1914. It is considered the greatest moment of peace during the conflict, as soldiers on both sides of the war temporarily laid down their arms and celebrated together, playing games and sharing food. While the truce only lasted for a few days, it served as a powerful reminder of the shared humanity between enemies.
