No, you didn’t read the title to this piece in correctly. During WW1, the Russians and the Germans formed a temporary truce to shoot the crap out of a bunch of wolves that kept trying to bite their faces off. The wolves, armed with nothing but teeth the desire to stab people with those teeth managed to over come heavily armed soldiers wielding rifles, grenades and the countless bottle of urine they no doubt had due to the constant soiling themselves that was bound to have occurred.
After facing ever respawning waves of wolves, soldiers on both sides quickly realised they were at the losing end of the lupine version of Call of Duty and decided that they had to work together. Which is exactly what they did, they cast aside orders to literally shoot each other in the face to shoot wolves instead. How this has yet to be a film, perhaps starring a 30ft CGI Liam Neeson, isn’t known. But just remember that at one point in time, two armies cast aside their differences to explode angry wolves. Rumour has it that chest hair was created at the exact moment those two armies shook hands.
