Approximately one year after the invasion, the city's Iraqi police and Iraqi Civil Defense Corps were unable to establish order. Insurgents launched many attacks, some on police stations in the city, killing at least 20 police officers. Beginning in early March 2004, the Army's 82nd Airborne Division commanded by Major-General Charles H. Swannack Jr. gave a transfer of authority of the al-Anbar province to the I Marine Expeditionary Force commanded by Lt. General Conway. The 3rd Cavalry and the 3rd Brigade of the 82nd Airborne were then sent home.
