Star Trek: The Quarterdeck Breed continuity
On or before Stardate 53441.4, the Agamemnon was under the command of Commander Henry Grayum and served within the Border Patrol division of Starfleet. It served on a reconnaissance mission which was ultimately successful in bringing down a rogue element of Breen that departed from the Treaty of Bajor. Following that mission, Grayum retired as a Captain, and command of the Agamemnon fell to Commander Richard D. James.
