Plagge was noted for his brutality, particularly to Jews. He participated in the gassing of thousands of Sinti and Roma people, and Jews from Theresienstadt. He was known for submitting prisoners to punishment in the form of physical exercises, known as "sport" in the camp. Prisoners in were also made to do these exercises. On demand, a group of prisoners were expected to undertake any action, such as walking, singing, running, crawling on one's elbows and tips of the toes, roll around on the ground covered with gravel and crushed bricks, etc. Plagge was a specialist in the invention of these exercises, which were to be performed very quickly without any regard to the age and health of the prisoners. He would make prisoners run for hours while carrying his pipe between his teeth, and hit those who fell, forcing them to carry on. Prisoners nicknamed him das Pfeifchen.
Trial
Plagge was prosecuted by the Supreme National Tribunal at the Auschwitz Trial in Kraków. During the trial he admitted to only beating prisoners. Hoping his life would be spared, he told the court that after atonement for his crimes, he will be regarded as a good man, but was sentenced to death due to the overwhelming evidence against him. He was executed on 22 January 1948 by hanging in Montelupich Prison, Kraków.
