In late 2266, Outpost 4 was one of several outposts which were attacked by the ChR Gal Gath'thong, a Romulan bird-of-prey. The Romulans powerful plasma torpedoes were easily able to overcome the outpost's rodinium shielding, and the first attack killed the majority of the occupants, but Hansen managed to survive.
He was able to communicate with the USS Enterprise about the nature of the attack, but Hansen, was later killed during a second attack by the Gal Gath'thong, in which the outpost was completely destroyed. (TOS episode: "Balance of Terror")
