Fiends of the Eastern Front

Fiends of the Eastern Front, created by Gerry Finlay-Day and Carlos Ezquerra, originally ran in 2000AD #152-161 in 1980. It told the story of Hans Schmitt, a young German soldier in World War II who discovers that the Romanian soldiers who are fighting alongside his unit are actually vampires under the command of the evil Captain Costanza and his second in command Sergeant Gorgo. Schmitt and his comrade Karl Mueller find themselves at more risk from the vampires than from the Allies.

Though originally a self contained story, a follow-up series later appeared in the Judge Dredd Megazine and the Fiends have also appeared in a series of novels by David Bishop.
