||Horton Salm was a Human male from the planet Norval II in the Calaron sector of the Outer Rim Territories who was a military officer of the Alliance to Restore the Republic and its successor, the New Republic. An accomplished pilot, leader, and training commander, he preferred to fly Koensayr Manufacturing BTL Y-wing starfighters over newer models, as he felt that the older craft were more reliable and would get him home in one piece. Salm led the Alliance's Gray Squadron at the Battle of Endor, surviving the run through the second Death Star's superstructure. Salm continued to command combat units, leading Aggressor Wing through the Battle of Brentaal IV nine months after Endor, an engagement that saw him promoted to the rank of general. Salm later led the Aggressors during the evacuation of Ciutric IV. By 6.5 ABY, Salm was assigned to the New Republic's Folor Base, training several new starfighter squadrons, including the reformed Rogue Squadron and his own Defender Wing. Despite clashes with Commander Wedge Antilles over Rogue Squadron's lack of discipline, and the presence of Tycho Celchu—a suspected sleeper agent of the Galactic Empire—as the unit's executive officer, Salm and his Defender Wing worked effectively with Rogue Squadron at the Battle of Vladet and the First Battle of Borleias. Salm was also one of the officers responsible for devising the plan that would eventually cause the planet Borleias to fall to the New Republic. Following the liberation of the galactic capital, Coruscant, Salm served as a judge presiding over the trial of Tycho Celchu. Celchu had been charged with treason and the murder of Rogue Squadron pilot Corran Horn during the operation to capture Coruscant. Salm was surprised to learn that Horn was in fact not dead, but had been captured by Director Ysanne Isard, the ruler of the Empire, and interred aboard the Super Star Destroyer Lusankya. Briefly resuming training duties, Salm was based at the Borleias starfighter training base before returning to active combat with a B-wing assault group for the New Republic's campaign against the Ciutric Hegemony, a former Imperial faction, in 9 ABY.
