Fox to the Hounds

The Republic starship USS Enterprise played fox to the hounds of four sister starships in a war game exercise. Equipped with the new M-5 computer, developed by Dr. Richard Daystrom, the inventor of the duotronic computer system, and stripped of most of her crew, the Enterprise became a killing machine. She disabled the USS Excalibur, killing her entire crew, and severely damaged the USS Lexington. Starfleet almost ordered the destruction of the Enterprise in self-defense, believing Kirk was engaging in a rampage, but in reality, the computer had spun out of control. Kirk managed to disable the computer and reassert control on the Enterprise before further trouble took place.
