In 2157, Jonathan Archer led a flotilla consisting of eight United Earth Starfleet vessels including the Enterprise to Gamma Hydra in search of a Vissian listening post, believed to be under the threat of a Romulan attack.
The Earth forces arrived in the sector, but they were intercepted and engaged by the Romulan attack force before they could locate the outpost. The heavily outnumbered Starfleet task force was soon overwhelmed despite putting up a fierce fight and destroying several enemy vessels. Their total annihilation was only averted by the timely arrival of a fleet of ten Vissian starships. With the losses they already sustained the Romulan forces became outnumbered, so Commander T'Met ordered a full retreat.
The Vissian forces were unable to prevent the listening post's destruction, the Earth task force lost five starships and the remaining vessels sustained heavy damage and casualties including Captain Duvall, commanding officer of the USS Gettysburg. To return some of Earth's good will, Enterprise was towed to Vissia Prime to a repair facility. (ENT - The Romulan War novel: To Brave the Storm)
