- "I've killed many people. Men, women, and children."
- ―Ernst Mueller to Roger Dooley
Committing War Crimes
Mueller joined the armed forces of the Third Reich and actively participated in World War II. He rose in ranks until he became a Colonel. During the war, he committed many war crimes, killing many people, including children. In 1944, on the Eastern Front, Mueller and his men were stationed in the area near Finow. When they searched for the Soviet troops, they discovered the bodies of hundreds of Soviet soldiers, massacred.
Roger Dooley's Visit
After the war, Mueller was arrested and tried at the International Military Tribunal in Nuremberg. He was sentenced to death by hanging. A day before the execution, he was visited by Roger Dooley who offered Mueller a pill to commit suicide and defy his captors if Mueller gave information on the battle at Finow. Mueller complied, thinking he was given a cyanide pill; but the pill was actually a breath mint and Mueller was hanged later that day.
- In the comics, Ernst Mueller was a member of Wolfgang von Strucker's Blitzkrieg Squad.
