Strategic Narrative Overview

For four years a stalemate persisted, with government and rebel forces each holding portions of the city. In July 2016 government troops, aided by Russian airstrikes, severed the rebels' last supply line, imposing a siege. Rebel counteroffensives in September and October 2016 failed to break the encirclement. In November, Syrian government forces launched a decisive offensive, systematically recapturing rebel-held eastern districts block by block.

01 / The Origins

The battle erupted on 19 July 2012 as part of the broader Syrian Civil War, when opposition militias including the Free Syrian Army and Al-Nusra Front moved to seize Aleppo, Syria's largest city by urban area. The Ba'athist Syrian government, backed by Iran, Hezbollah, IRGC-linked Shia militant groups, and later Russia, fought to retain control, while Kurdish YPG forces held separate zones within the city.

03 / The Outcome

By December 2016 the Syrian government had retaken all of Aleppo, forcing surviving rebel fighters and civilians to evacuate under a brokered agreement. The victory was broadly regarded as a turning point in the civil war, significantly weakening the armed opposition. The battle left the Old City severely damaged, drew widespread international condemnation for atrocities committed by multiple parties, and displaced hundreds of thousands of residents.
