In 2401, at the height of the Klingon-Gorn War, Captain Zachary MacAllister ignored direct orders from Starfleet Command and attempted to take the Lindberg into Gorn space to aid the Hegemony against the Klingons.
After three days in the war zone the Lindberg was confronted by a Klingon patrol. MacAllister ordered his crew to attack, but instead his first officer and chief medical officer attempted to remove him from duty and surrender. MacAllister and his supporters instead fought their way to a shuttle bay, and MacAllister escaped. He remained a fugitive through 2409. (ST website: The Path to 2409)
