Thomas Theisman

Thomas Theisman is a fictional character in the Honorverse. He was born on Haven to an unmarried teenager. He joined the Navy immediately after high school. He was sent to Masada to command the starship Principality as part of a proxy war. He soon realized the Masadans were very dishonorable allies.

He respects Honor Harrington as a leader of men, and Lester Tourville has equal respect for him. Unlike Esther McQueen, he is not viewed as dangerously ambitious by the Committee of Public Safety. When she dies, he is appointed fleet admiral - and reveals his true motives. He leads an assault on the Committee and kills Oscar Saint-Just, ending the rule of the People's Republic of Haven. It is said that he restored the honor of the People's Navy. He turns down the offer of the Presidency of the reinstated Republic of Haven, and lets Eloise Pritchart take that position.
