Flegel cooperated with many high officers and nobles against von Lohengramm. In particular, he incited Sussanna von Beenemünde into plots to kill Reinhard or his sister, all while being careful no definitive evidence could be traced back to himself. He was aboard Iserlohn Fortress, holding the rank of Vice Admiral under Fleet Admiral Gregor von Mückenberger who valued his political connections. Flegel accompanied von Mückenberger aboard his flagship at the Fourth Battle of Tiamat.
Following the Battle, Flegel returned to Odin in 487 Imperial Calendar and conspired with Branschweig to ensure that Reinhard would die in his next campaign. It was his proposal to leak Imperial plans to Fezzan, correctly guessing that the information would be sold to the Free Planets Alliance.
Having been present at the formation of the Lippstadt Alliance, Flegel served his uncle as a Vice Admiral during the Imperial Civil War and died in a mutiny after insisting his ship make a suicide charge. His last words were "Long Live the Empire."
