"...or laugh at their stupidity!"―Oetzmann[src]
Oetzmann was a captain in the German army, serving in the area of Verdun during World War I. In September 1916, he and his fellow officer, Hans Lehmann served in a German command bunker in the trenches in the Battle of Verdun. While enjoying a cup of tea one evening, Lehmann expressed his desire to have a chance with Oetzmann's lover, Heidi. Oetzmann shrugged his friend off with a laugh. As they continued to joke, Lehmann heard a noise outside, and Oetzmann summoned a German corporal to investigate it.
With the soldier dismissed, Oetzmann leaned in to confirm a rumor that Lehmann had heard. Lehmann stated that his brother-in-law had overheard two generals mentioning that they were bringing in two Big Bertha guns that night. Not aware that a French spy was listening to their conversation, they joked about having the French army meeting the two lovely "German girls." It is not known whether Oetzmann survived after a grenade thrown by the spy ignited several boxes of explosives near the bunker.
