On 16 October 2016, Iraqi Prime Minister Haider al-Abadi declared the beginning of the assault to recapture the city of Mosul. Officials reported howitzers firing on ISIL targets later that day. The main assault began on 17 October at approximately 6 a.m., local time, with shelling and the arrival of armored vehicles to the front lines. The Peshmerga in the Khazir region, east of Mosul, started the ground assault by advancing on ISIL-held villages from three fronts, while Iraqi security forces advanced from the south. Iraqi troops advanced on the Bartella area east of Mosul while ISIL fighters fired mortars at Peshmerga. The President of KRG, Massoud Barzani, said that Peshmerga and Iraqi government fighters retook 200 square kilometers (80 square miles) from ISIL on the first day of fighting. Iraqi government officials reported that "heavy losses of life and equipment" were inflicted upon ISIL fighters in the Hamdaniya district southeast of Mosul. ISIL fighters who were wounded in the battle were reported to have been bussed towards its Syrian headquarters of Raqqa for medical aid. The anti-ISIL coalition destroyed 52 targets during the day. Family members of ISIL fighters fled from Mosul to the village of Nawran due to the shelling.

ISIL was also reported to have evacuated and shifted its headquarters from the west side of Mosul to its east side. A bridge into Mosul known as the "Freedom Bridge" was destroyed. Peshmerga sources blamed ISIL for its destruction, while ISIL claimed it was destroyed by airstrikes.

18 October

On 18 October, the Iraqi government declared that twenty villages near Mosul were captured from ISIL in the first 24 hours of fighting by the Peshmerga and Iraqi forces. On the southern front, Iraqi troops retook several villages near Qayyarah, including al-Sirt, Bajwaniya, al-Hud, and al-Mashraf, and parts of the al-Hamdaniya District southeast of Mosul. Iraqi Federal Police also regained control of 56 oilfields in the Qayyarah district. According to reports, the Peshmerga met little resistance on the eastern front, while Iraqi and PMF fighters coming from the south were facing tougher resistance from ISIL.

The coalition strategy was reported to be to encircle Mosul completely, after which Iraqi troops would advance into the city-center. Early in the day on 18 October, Iraqi forces in the east came close to Qaraqosh (Bakhdida), once the largest Assyrian town in Iraq, and fighters in the south were closing in on Hammam al-'Alil. Iraqi Army forces later stormed Qaraqosh and fought with ISIL fighters who remained holed up. The Iraqi and Peshmerga advance had been slowed down during the same day due to suicide bombers, roadside IEDs and oil fires. In order to eliminate any ISIL presence completely from the villages on the outskirts of the city, they were carrying out street-by-street search operations. The Peshmerga later paused their advance while the Iraqi Army continued its advance.

Pro-government fighters in the south of Mosul were battling pockets of ISIL fighters and snipers as they tried to reclaim the village of Abbasi, and expected to soon take control of the village of Zawiya. Fighting resumed in the village of Kani Harami, which was captured by the Iraqi Army a day earlier but recaptured by ISIL on 18 October as the Army lacked reinforcements. The Army also retook the village of Al-Hud on the Tigris, where villagers had risen up against ISIL and killed at least 9 militants. State police also secured the Al-Mishraq sulfur plant south of Mosul. The al-Shura district was stated by its mayor to have been captured by the Iraqi security forces.
