Andreoni was the captain of the USS Exeter in 2270. Under Andreoni's command, the Exeter went to the Ciatella star system with three other ships, at the suggestion of Ambassador Ben Shamirian, to rescue Captain James T. Kirk and the USS Enterprise. The ships turned the tide of battle with ships of various hostile powers that were seeking to capture the transwarp technology aboard Enterprise. (TOS - Fortunes of War novel: Battlestations!)
