By 22 August 2011, rebel fighters had entered Tripoli and occupied Green Square, which they renamed Martyrs' Square in honour of those killed since 17 February 2011. On 20 October 2011, the last heavy fighting of the uprising came to an end in the city of Sirte. The Battle of Sirte was both the last decisive battle and the last one in general of the First Libyan Civil War where Gaddafi was captured and killed. The defeat of loyalist forces was celebrated on 23 October 2011, three days after the fall of Sirte.
