The MEU and the Mahdi Army first exchanged fire on 2 August. A patrol by Combined Anti-Armor Team (CAAT) Alpha, Weapons Company, 1st Battalion, 4th Marines (1/4) approached a maternity clinic located directly across the street from the home of Muqtada al-Sadr on the outskirts of the city. The clinic was in an area authorized for U.S. presence under a June cease-fire agreement brokered between coalition forces and Muqtada Sadr by the governor of Najaf, other local civic leaders, and the Bayt al-Shia (the informal council of senior Shia clerics). The Marines reported over 70 enemy dead after nearly an hour of fighting. The Mahdi Army kept a steady resupply of men and weapons coming out of the Wadi-us-Salaam cemetery. CAAT Alpha faced mortars, RPGs (Rocket Propelled Grenades) and small arms fire with one Marine wounded until the unit ran low on ammunition. 1/4's Bravo Company was sent in on 7-ton trucks to provide covering fire for CAAT Alpha. Both sides withdrew to their respective strongholds soon afterwards.
