In 2409 Captain Kel was contacted by Jurlek, a Klingon Defense Force officer commanding a B'rel-class bird-of-prey. He offered to return a captured Federation prisoner of war, Franklin Drake of Section 31, and gave her the location where the prisoner would be transferred to his ship from the IKS Seg'pa for transport to Qo'noS.
Kel arrived in-system in the Musashi and opened fire, beaming several away teams aboard the bird-of-prey to retrieve Drake. The plan soon went wrong, however, as Jurlek's treason was discovered and he was challenged and killed by his second officer. This officer then attacked with the Seg'pa after a brief parley, destroying the Musashi with all hands. (STO - "Tutorial" missions: "End of Watch", "Intruder Alert", "Your New Command")
