"The armistice was an event of significance for those involved, even if its contemporaneous meaning was not the defiant moral that was imposed on it long afterward. The truce meant time off for weary soldiers, providing them with an opportunity to move about in the lines without fear of snipers, rebuild their trenches, and enjoy Christmas as best they could under the circumstances, as well as a chance to satisfy their curiosity about the enemy and write home about something besides the endless mud and shelling. The holiday cease-fire became a valued memory for the participants, as demonstrated by the way it was discussed in letters written by the soldiers, fondly recalled years later in interviews and memoirs describing their service, and featured in many regimental histories."
