Battle of Mosul

Battle of Mosul

The Battle of Mosul was a major urban offensive in which Iraqi and allied forces expelled Islamic State of Iraq and the Levant (ISIL) from Mosul between October 2016 and July 2017. The operation involved Iraqi federal forces, Kurdistan Regional Government Peshmerga, Shia Popular Mobilization Forces, and an international anti-ISIL coalition led by the United States Department of Defense, with extensive aerial and artillery support. The fighting marked a turning point in the Iraq War (2013–2017) and had significant regional implications for Syria, Turkey, and Iran.

Background

By June 2014 ISIL had captured Mosul during a rapid offensive that included the collapse of the Iraqi Army (pre-2014) units and the fall of Nineveh Governorate provincial institutions. ISIL declared a Caliphate centered on Raqqa and Mosul, provoking multinational efforts including the Combined Joint Task Force – Operation Inherent Resolve and diplomatic initiatives by the United Nations Security Council, Arab League, and bilateral actors such as Iran, United States, and Russia. The organization used guerrilla warfare tactics, improvised explosive devices, and propaganda via Al Hayat Media Center to entrench control. The strategic importance of Mosul derived from its population, historical status as Iraq's second city, and proximity to Kirkuk oilfields and the Syria–Iraq border.

Combatants and Commanders

Primary anti-ISIL forces included the Iraqi Armed Forces—notably the Iraqi Counter Terrorism Service (ICTS or Golden Division), the Nineveh Operations Command, and the Iraqi Army 16th Division—supported by Peshmerga forces under the Kurdistan Regional Government and Shia militias organized within the Popular Mobilization Forces (PMF) under leaders associated with the Hashed al-Shaabi structure. International partners included the United States Armed Forces, the United Kingdom Armed Forces, the governments of France, Canada, Australia, Germany, and others contributing to coalition airstrikes and training by Combined Joint Task Force – Operation Inherent Resolve. Commanders on the Iraqi side featured figures such as Abadi, Najm al-Jubouri? (use proper names: Talib Shaghati), and ICTS leadership; ISIL command within Mosul operated through local emirs and central staff appointed by Abu Bakr al-Baghdadi's inner circle.

Course of the Battle

The offensive began with coordinated operations from multiple axes: east of the Tigris River, south from Qayyarah and Al-Shura, and north from Hamam al-Alil and Bashiqa where Peshmerga had contested positions. Iraqi forces advanced through suburbs like Eishtah and Bartella, employing urban warfare tactics against ISIL defensive networks of tunnels and IEDs. Coalition air power and artillery targeted fortifications and command-and-control nodes, while Iraqi counterterrorism units led house-to-house clearing in central districts including Old Mosul and the University of Mosul precinct. ISIL responded with suicide vehicle-borne improvised explosive devices, snipers, chemical-weapons allegations, and human shields, holding river crossings and historic neighborhoods. After seizing the eastern half of the city, pro-government forces crossed the Tigris River and contested western neighborhoods such as Al-Nuri Mosque vicinity, culminating in the destruction of the mosque's minaret during fighting. The final phase saw systematic clearance of dense neighborhoods like Al-Farooq and Al-Shifa, with insurgent leaders killed or captured and ISIL fighters fleeing toward Tal Afar and Syria.

Casualties and Humanitarian Impact

Casualties included thousands of combatant deaths among Iraqi forces, ISIL fighters, and militia elements, with estimates varying across sources. Civilian casualties numbered in the thousands, including deaths from airstrikes, artillery, and ground combat; large-scale displacement produced a humanitarian crisis affecting internally displaced persons (IDPs) who sought refuge in Erbil, Anbar Governorate camps, and Duhok. Critical infrastructure—hospitals such as the Mosul General Hospital, water-treatment facilities, and power grids—suffered extensive damage, exacerbating risks of disease and malnutrition. Cultural heritage sites, including the Mosul Museum, historic mosques, and archaeological artifacts linked to Nineveh and the Assyrian Empire, were looted or destroyed, drawing condemnation from the UNESCO and human-rights groups like Human Rights Watch and Amnesty International.

Aftermath and Reconstruction

The post-battle period involved stabilization, demining, and reconstruction coordinated by the Iraqi Ministry of Reconstruction, provincial authorities in Nineveh Governorate, international donors, and NGOs including International Committee of the Red Cross and United Nations Assistance Mission for Iraq. Efforts addressed housing rehabilitation, restoration of municipal services, and prosecution of suspected ISIL members in courts influenced by the Iraqi Penal Code. Political tensions persisted among the Kurdistan Regional Government, Baghdad, and Popular Mobilization Forces over administration and security arrangements. Reconstruction faced challenges from funding shortfalls, sectarian grievances, and the scale of unexploded ordnance; heritage restoration projects worked with institutions such as UNESCO and academic partners to recover artifacts. The liberation of Mosul shifted momentum in the broader anti-ISIL campaign, preceding subsequent operations in Tal Afar and Al-Bab, and shaping regional dynamics involving Turkey, Iran, and coalition members.
