Basra and Sadr City, 2008

Basra: Charge of the Knights
The Iraqi government launched Operation Charge of the Knights to retake Basra from militias. The early fighting went badly for Iraqi forces, and U.S. and British support proved essential. The militia ultimately withdrew from the city, and the operation is widely regarded as a strategic success for the Iraqi government.
Sadr City
As fighting broke out in Basra, militia fighters in Baghdad's Sadr City launched rockets at the Green Zone. U.S. and Iraqi forces pushed into the southern districts and built a concrete barrier along al-Quds Street to deny rocket teams access. A ceasefire took effect on May 11, and the following day an agreement allowed Iraqi forces to enter Sadr City.
Significance
The 2008 battles marked a turning point in which Iraqi forces led major operations, with Americans in support.
