The Battle of Douma was a military engagement during the Syrian civil war. The battle began on 21 January 2012, after Free Syrian Army fighters changed their tactics from attack and retreat guerrilla warfare in the suburbs of Damascus to all-out assault on army units. Earlier in January, the FSA had taken the town of Zabadani, and consequently gained control over large portions of Douma. After a general offensive in the suburbs, Douma was retaken by the Syrian army at the same time as the other rebelling suburbs.
