The Earth Starfleet starships Enterprise, SS Intrepid, and Republic were escorting a supply convoy through the Vorkado system when they detected a Romulan warbird, the IRW Aoi'fvienn, entering the system.
The Republic and Intrepid executed a highly coordinated maneuver to dispatch the Romulan vessel while the Enterprise stayed behind to protect the convoy. Having heavily outnumbered and already damaged by a prious fight with an Andorian convoy, Captain Khazara executed an escape manuver by extending Aoi'fvienn's shields and igniting the ship's warp plasma, disableing the two attacking Earth ships. Commodore Jonathan Archer decided not to pursue the Romulan vessel, but to assist the Republic and Intrepid and keep the convoy protected. (ENT - The Romulan War novel: To Brave the Storm)
The attack left Archer's close friend, Captain Carlos Ramirez dead and Lieutenant Travis Mayweather gravely wounded. The tactic employed by Khazara made it into history, and more than two centuries later it was used by the USS Voyager's Doctor to save the ship.
