Monsieur Gravedigger is a short Foreign Legion tale found in Weird War Tales comic issue #2 (v1 002, Nov-Dec 1971). The title alone as well as the setting sounds like classic P.C. Wren who often gave his fictional legionnaires nicknames–who can forget Sergeant-Major Suicide-Maker. The fort is straight out of Beau Geste (the movie) and aptly named by the mutineer in this story “Madame La Republique’s Mud Oven”. There are lots of other good classic Foreign Legion plot devices all packed into one great nine page story.
Weird War Tales was an exceptionally well done comic with a 12 year / 124 issue run. The artwork is top notch and the well written stories are very entertaining. The anthology format that jumped throughout history also appeals to me–as some of the WWII or Korean War settings of other war comics got repetitive. There is a Showcase collection of the first 21 issues available.
