This is a set of photographs that was shot on an iPhone in the Arghandab Valley, Kandahar, Afghanistan in April and May 2011. The US soldiers I was embedded with, 1 Platoon, Delta Company, 1-66 Infantry, 4th Infantry Division, received information that the Taliban were planning a large scale offensive, including several simultaneous attacks on outlying outposts. Their base, Combat Outpost TJ, was a prime target, and so the soldiers redoubled their efforts to improve their defences. There followed 3 frantic days of building new walls, hammering posts, and laying barbed and razor wire. The offensive, however, never materialised.
