The Pagak offensive was a major military operation by the South Sudanese government during the South Sudanese Civil War with the aim of capturing the strategic town of Pagak and the wider Maiwut County from Riek Machar's SPLM-IO rebels. Since the civil war's beginning, Pagak had served as headquarters and stronghold for the rebels, and its loss was believed to possibly greatly weaken the insurgency. A large part of the government forces that took part in the offensive are members of the SPLM-IO (Juba faction), a break-away group from Machar's movement that is loyal to First Vice President Taban Deng Gai. Though pro-government forces managed to capture Pagak on 6 August, their attempts to secure the surrounding areas proved unsuccessful. As result, the SPLA-held corridor between Mathiang and Pagak remained unsafe.
