The "Wolf truce" was an incident purported to have occurred in February 1917, when Russian and German soldiers on the Eastern Front of World War I were reported to have called a truce in order to fight off the wolves of the Polish and Baltic Russian stretches. The half-starved wolves of the Kovno-Wilna-Minsk district plagued both German and Russian fighting forces, even menacing the men in the trenches. Both sides used poison, rifle fire, hand grenades, and machine-guns against the wolf packs, with fresh packs appearing in place of those that were killed by the Russian and German troops. As a last resort, both the Germans and Russians were said to have called a temporary truce in order to overcome the wolf plague, with several hundred wolvse being rounded up and killed. "Wolf truces" were reported by the Bridgeport Evening Farmer on 15 February 1917, the Hopkinsville Kentuckian on 22 February, the Alaskan Daily Empire on 16 March, and the New York Times on 29 July 1917; however, there was no evidence for such an occurrence in Russian records.
