The Siege of AR-558 was a brutal engagement during the Dominion War between the ground forces of the United Federation of Planets and the Dominion. AR-558 was a small planet in the Chin'Toka system, which was assaulted by Federation ground troops after the system was taken during the First Battle of Chin'Toka. The planet housed a Dominion subspace communication array, which the Federation could use to garner massive intelligence on the Dominion's movements.
When the Federation soldiers landed, the defending Jem'Hadar were pushed out of the relay station, however they planted dozens of cloaked mines throughout the facility which the Federation soldiers nicknamed "Houdinis". Over 147 soldiers were left to guard the station while engineers could disable the communications array's security grids and gather the intelligence required. Because the Federation hold on the Chin'Toka system was so fractured, reinforcing the planet and merely re-supplying it was a massive problem; Jem'Hadar attack ships frequently ambushed Federation ships on supply runs.
The Jem'Hadar placed in excess of 2 Columns on the planet, and they frequently attacked the Federation held-outpost. The Federation soldiers stationed there were supposed to be relieved after 90 days, however they were left on the planet for 5 months. Amongst the casualties of the defenders were the contingents commanding officer. By the time the USS Defiant arrived on a supply run, 104 of the defending soldiers were killed; the remaining 43 suffering from combat stress and post traumatic stress syndrome. A small contingent of the Defiant crew decided to stay on the planet, which only bolstered its defences to a mere 48.
The extra expertise of the Defiant crew allowed the Houdini mines to be located, vastly reducing the chances of further casualties. A scouting mission led by Nog, who had the extra advantage of sensitive hearing, located the Jem'Hadar camp and confirmed the size of the force at two columns, vastly outnumbering the defenders. However, Nog was badly wounded during the mission. The defenders resolved to make a final stand; the Houdinis would be placed in a ravine, where it would catch the Jem'Hadar in a bottleneck.
During the final attack, the Jem'Hadar were caught in the ambush by the mines, however, they still had advantage in numbers and stormed the Starfleet defences. Despite being outnumbered, the Federation forces managed to repel the Dominion forces, the station still in Starfleet hands. At least 7 Starfleet officers and 30 Jem'Hadar were killed in the final assault. Following the battle, the Federation landed a relief force, including an engineering crew to take care of the communications array. The station remained in Federation hands until the Chin'Toka system was re-taken by the Breen.
