On October 2, 2006, the Third Platoon, A/1/32 10th Mountain Division is told to move south in the notorious Korengal Valley and try to open good relations with the local elders of Dokalbot Village. Told by the Korengali elders that they are not wanted, the platoon turns back for the KOP only to be ambushed from all sides.
