The Battle of Husybah was fought in the spring of 2004 at the same time as the First Battle of Fallujah. In April 2004, Fallujah was under siege by United States Marines, and insurgents were looking to relieve pressure on the city by attempting an offensive of their own. Ten days before, the highway connecting Al Anbar to Baghdad was cut and the insurgents attacked the capital of the province, Ramadi. The attack was repulsed by the Marines and the battle resulted in heavy casualties on both sides. Now the insurgents were ready for another attack, on the city of Husaybah on the Syrian border.
