The Second Battle of Fallujah—code-named Operation Al-Fajr (Arabic: الفجر‎, lit. 'the dawn') and Operation Phantom Fury—was a joint American, Iraqi-government, and British offensive in November and December 2004, the highest point of conflict during the Iraq War. It was led by the U.S. Marines against the Iraqi insurgents in the city of Fallujah, and was authorized by the U.S.-appointed Iraqi Interim Government. The U.S. military called it "some of the heaviest urban combat U.S. Marines have been involved in since the Battle of Huế City in Vietnam in 1968."
