The Korangal Valley campaign was a series of military operations conducted by ISAF forces against Taliban insurgents in the Korangal Valley in Kunar province, Afghanistan, from October 2004 to April 2010. The campaign ended with a US withdrawal from the valley, after suffering heavy casualties, and a Taliban takeover of the area. US positions were attacked with rockets and mortars on an almost daily basis, and patrols were routinely ambushed after advancing only a few hundred meters outside the wire.
