" The objective was simple: capture or kill the brutal leader of a kidnapping ring with ties to the Islamic State of Iraq (ISI), a terrorist group devoted to the overthrow of the democratically elected Iraqi government. By September 2007, many of the sectarian militias and insurgent groups had been pushed out of central Baghdad and into havens outside the capital. Samarra, a historic city on the Tigris River, eighty miles north of Baghdad became the refuge for a particularly vicious insurgent faction. "
