World War I was a tragic war for many reasons. It was the first war in which modern weapons like machine guns were used. Sadly, the military leaders of the time would not change their tactics—they still expected soldiers to overwhelm the enemy by charging as a group directly at the enemy’s position. Not only were casualties horrific, the whole war could have easily been avoided if not for the ambitions of a few world leaders. But when Christmas day came in 1914, something amazing happened. The soldiers simply stopped fighting. In Truce: The Day the Soldiers Stopped Fighting, Jim Murphy does a great job of explaining World War I so clearly that you can easily understand how the soldiers felt when they called their own truce on Christmas Day.
