The Salline Pacification represents an early conflict within the broader Galactic Civil War, pitting the forces of the Galactic Empire against those of the Rebel Alliance. This event transpired sometime between 2 BBY and 0 BBY, with Imperial forces, under the command of Colonel Maximilian Veers, launching an offensive against Rebel insurgents located within the port city of Salline on the Core World of Chandrila.
It was claimed that the Rebel Alliance had taken control of Salline. However, Mon Mothma stated that the Rebels were not involved. She claimed the Governing council of the city were protesting the capture of its citizens by the ISB, and the Imperial Governor regarded them as traitors. Regardless, Colonel Maximilian Veers and his Imperial forces were sent to restore order.
To prevent a recurrence of the earlier Debacle on Ord Torrenze, Colonel Veers requested two AT-ATs, designated Hammer 6 and 8, for direct fire support, and four AT-STs to support the AT-ATs. These units were deployed via dropships from the Star Destroyer, Viscount, and moved into position before advancing on Salline at 0200 hours. While the government center on the coast was heavily fortified, all of downtown Salline was designated a free-fire zone. Veers positioned Hammer 6 as the lead element, with Hammer 8 following 200 meters behind, under his command. Each AT-AT was flanked by two AT-STs as they advanced down Guildhead's Way toward the government center. At a distance of 1.2 kilometers from their objective, Hammer 6 was attacked by enemy troops concealed in the upper levels of a building on the south side. Hammer 8's chin cannons destroyed the building, and the AT-STs eliminated the troops as they attempted to escape through the ground floor, having learned from the Debacle on Ord Torrenze.
Another 400 meters further, the same tactic was employed again, but this time the enemy troops managed to disable Hammer 6 when a missile struck the rear hip of the walker, exacerbating an existing maintenance issue. Veers ordered the vehicle to remain in place, providing elevated fire support with a 180-degree arc of fire. Hammer 8, now in the lead, breached the security wall upon arrival, and Veers demanded surrender via loudspeaker. Before Hammer 8's Stormtrooper contingent could rappel down to engage, the enemy force escaped via watercraft from the docks. However, TIE fighters, dispatched by Veers, destroyed them seven kilometers south of Salline.
