In the battle, a scout platoon from the 1st Battalion, 133rd Infantry Regiment, United States Army, 6 MARSOC special forces officers, 20 Afghan soldiers, and two United States Air Force Tactical Air Control Party (TACP) operators and one Law Enforcement Professional (LEP) retired police officer were ambushed by an estimated 400-500 Taliban near the village of Do Ab.

With assistance from close air support, the coalition forces repulsed the ambush, killing approximately 270 Taliban.

After receiving reports of Taliban fighters massing to attack Forward Operating Base Kalagush, a scout platoon from the 1st Battalion, 133rd Infantry Regiment, plus 20 Afghan soldiers and two US Air Force TACPs, and one Law Enforcement Professional (LEP) were airlifted by a pair of Chinook helicopters to a small landing zone in a canyon near the village of Do Ab.

Later in the day, Chinooks delivered a half team of U.S. special operations forces and Afghan commandos to support the surrounded Coalition troops.

Instead, Coalition forces conducted periodic sweeps or raids in the province to cull the numbers of occupying Taliban militants.
