The Siege of AR-558 was a ground battle between Starfleet and the Dominion during the Dominion War.
In 2375, Starfleet sent Benjamin Sisko and the crew of the USS Defiant to resupply AR-558, a planet in the Chin'toka system that housed a Dominion communication array that the Jem'Hadar had been attacking the Starfleet ground forces to recapture. Seeing the direness of the situation faced by the Starfleet forces, Sisko, Julian Bashir, Ezri Dax, Nog and Quark remained on AR-558. Nog lost his left leg during a Jem'Hadar attack. Sisko later led the Starfleet forces against the Jem'Hadar, a battle which was helped by taking control of the Dominion Houdini mines and using them against the Jem'Hadar. (DS9 episode: "The Siege of AR-558")
Bashir recalled the siege of AR-558 in 2385, remembering his lack of sleep and experience of double vision. (ST - The Fall novel: A Ceremony of Losses)
