The Taliban surrounded the remote base and its observation post and attacked it from the Quam and the surrounding farmland. They destroyed much of the Americans' heavy munitions, broke through U.S. lines, and entered the main base before being repelled by artillery and aircraft. American casualties included nine killed and 27 wounded, while four Afghan National Army (ANA) soldiers were wounded. The U.S. combat deaths represent the most in a single battle since the start of U.S. operations in 2001.
