The main assault began on 17 October at approximately 6a.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 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.
