This report, the second in a series, describes the purpose, course, and results of Coalition operations in Baghdad during the first three weeks of Operation Enforcing the Law (also known as the Baghdad Security Plan), from General Petraeus’ assumption of command on February 10, 2007, through March 5. It describes the flow of American and Iraqi forces into Baghdad; American and Iraqi command relationships; the efforts of those forces to prepare positions and develop intelligence in critical neighborhoods; the limited clearing operations that the forces already in Baghdad have conducted; and operations against the so-called Mahdi army, or Jaysh al Mahdi, in Baghdad. It describes and evaluates the apparent responses of the Jaysh al Mahdi and al Qaeda to these preparations and early operations, and highlights some of the differences between this operation and last year’s offensives in Baghdad, Operations Together Forward I and II.
