On 3–4 May, an infantry company from the 10th Mountain Division attempted to isolate the Mahdi Army along the eastern boundary of Sadr City by placing barriers along major intersections. This was an effort to facilitate the Iraqi Army's movement into Sadr City. The U.S. forces met with strong opposition as militants attacked the soldiers with heavy machine guns, RPGs, and IEDs. The unit suffered heavy damages to men, weapons, and equipment, but maintained pressure on the militia and controlled the grounds. Using close air support, tanks, and armoured vehicles the soldiers defeated militia strongholds along the eastern sections of Sadr City.
