Second Battle of Fallujah

The Second Battle of Fallujah, initially codenamed Operation Phantom Fury, Operation al-Fajr (Arabic: الفجر, lit. 'The Dawn') was an American-led offensive of the Iraq War that began on 7 November 2004 and lasted about six weeks. A joint military effort of the United States, the Iraqi Interim Government, and the United Kingdom, the battle was the war's first major engagement fought solely against the Iraqi insurgency, not the military forces of the Ba'athist Iraq government.
