Battle of Aleppo (2012–2016)

The Battle of Aleppo was one of the most significant and devastating confrontations of the Syrian Civil War. Spanning over four years, from July 19, 2012, to December 22, 2016, the battle transformed Syria's second-largest city into a fragmented landscape of urban warfare, sieges, and humanitarian crisis.

The conflict pitted the Syrian Arab Army (SAA) and its international allies against a diverse array of opposition forces, including the Free Syrian Army (FSA) and various Islamist factions. The struggle for Aleppo was not merely a fight for territory but a strategic pivot point for the entire Syrian conflict, involving major global powers and regional militias.

Course of the Battle

2012–2013: Initial Assaults and Stalemate

The battle began in July 2012 when rebel forces launched an attack to capture the city. By late 2012, the city was effectively split, with rebels holding the east and the government maintaining control of the west. This period was marked by fierce urban combat and a series of advances and counter-advances.

2014–2015: Encirclement and Attrition

By 2014, the Syrian government began a strategy of encirclement, attempting to cut off rebel supply lines. The conflict evolved into a war of attrition, characterized by prolonged shelling and the use of barrel bombs (improvised explosive devices dropped from helicopters) by government forces.

2016: The Final Siege and Evacuation

The tide turned decisively in 2016. Government forces, bolstered by Russian airpower, successfully cut off the final supply routes into eastern Aleppo. After a brutal siege, the remaining rebel forces were defeated. In December 2016, a deal was reached to evacuate the remaining fighters and civilians from the east to other rebel-held areas.
