Om det är en skröna så är den väl spridd. Har hört talas om den genom kontakter med tyskar tidigare. En samtida skriftlig källa jag känner till är från New York Times.
Vore inte alltför unik isåfall. Det finns åtskilliga exempel på vargattacker på grupper av människor. Ett välkänt exempel är Wolves of Paris

RUSSIANS AND GERMANS A Remarkable Armistice
LONDON. Saturday.
A Russian official message says: 'In the region of Tirul swamp we tookthe offensive and dislodged the enemy,taking some prisoners, but withdrewunder German pressure. "We ad-vanced a mile in the direction of
Kalngen, but fell back before counter-attacks. General Ivanhkevitch, who led the first line, was wounded, butremained at his post."
Rome advices from Petrograd re- port great German reinforcementson the Riga front Under Hindenburg'spersonal direction. Berne states that the Swiss frontier contiguous to Ger-many remains rigorously closed.
Packs of hungry wolves infest thePolesie front, and the soldiers arebeating them off with machine guns.In some cases Germans joined Rus-sians in fighting the wolves. Recentlythe Russo-Germans suspended a hotencounter and organised a joint huntto drive off the wolves. Afterwardsthey returned to their trenches. Therewas no treachery on either side.
