"Incident in New Baghdad" & What Really Happened
On 12 July 2007, [...] Bravo Company, 2nd Battalion, 16th Infantry Regiment embarked on a mission to clear Al-Amin District of New Baghdad of Anti-Iraqi Forces, aka Mehdi Militia, aka Jayish al-Mahdi in order to provide freedom of maneuver to Coalition Forces.
