O'Shea
From Memory Alpha, the free Star Trek reference.
He was injured during the Orions attack on his vessel. Dr. McCoy performed minor surgery on O'Shea and he later made a full recovery. (TAS: "The Pirates of Orion")
Background
O'Shea was one of the voices played by James Doohan. O'Shea, like his fellow crewmembers, wore no rank insignia. It is therefore unclear as to if he was a captain by rank, or by position only.
