The Fezzan campaign was a military campaign conducted by the National Liberation Army to take control of southwestern Libya during the Libyan Civil War. During April to June 2011, anti-Gaddafi forces gained control of most of the eastern part of the southern desert region (i.e. the southern part of Cyrenaica) during the Cyrenaican desert campaign. In July, Qatrun changed to anti-Gaddafi control on 17 July and back to pro-Gaddafi control on 23 July. In late August, anti- and pro-Gaddafi forces struggled for control of Sabha.
