Described by the U.S. government as the biggest ground operation in Afghanistan since the fall of the Taliban in late 2001,[1] the offensive led to the capture of more than 100 suspects and the deaths of 10.

The operation was marred by the accidental killings of 15 children in raids on suspected insurgents.

The operation involved 2,000 U.S. soldiers supported by Western backed Afghan troops, but failed to engage any Taliban or allied insurgents.

Patrols were conducted and caves searched over a 40 square mile (100 km2) area.
