Zeitz also reports on a strange incident during the battle. A German patrol sneaks up on two young and obviously inexperienced French soldiers:
"[...] they would make an easy kill. But the [veteran] German soldiers [do not want to take the lives of] a few young boys. […] Then one of the Germans puts his rifle aside, makes a huge snowball and throws it at the Frenchman's head. Astonished, the Frenchman turns around. […] then he accepts the strange fight with the happy blood of his nation. […] A snowball fight! [...] Laughing and joking loudly, Germans and Frenchmen throw snowballs at each other. The noise attracted attention and other men from both sides rushed to join in the strange fight." (Zeitz, 320f.)
