On 4 June, Iraqi police, under the command of Lieutenant General Mahdi Gharawi, cornered ISIL military leader
Abu Abdulrahman al-Bilawiin Iraq. Al-Bilawi blew himself up and Gharawi hoped it would prevent an attack.
[19] At 02:30 in morning, ISIL convoys of pickup trucks, each truck carrying four fighters, entered Mosul by shooting at the city's checkpoints. Though Mosul's first line of defense was thought to contain 2,500 soldiers, Gharawi says that "reality was closer to 500". He noted that since all of the city's tanks were being used by Iraqi forces in the
Anbar province, the city was left with little to combat the ISIL fighters. The insurgents hanged, burned, and crucified some Iraqi soldiers during their attack.
[19] ISIL commander Abu Abdulrahman al-Bilawi was killed near Mosul that day.
[20] On 5 June, a curfew was imposed in the city.
[21] The government used helicopters to bomb the militants. In the southern part of the city, five suicide bombers blasted an arsenal.
[22] ISIL began their attack on the northwestern part of the city on 6 June. The ISIL forces in the city totaled 1,500 soldiers, outnumbered by Iraqi forces by 15 to 1.
[23] Two suicide bomber cars exploded, in Muwaffakiya, a village near Mosul, killing six
Sabak soldiers. After the attacks, most of the fighters either retreated into the desert or camouflaged among the local population.

On 8 June, the group launched a double bomb attack against a
Patriotic Union of Kurdistanparty office in
Jalula, in which eighteen people died.
[24] That day, about a hundred vehicles entered Mosul, carrying at least four hundred men.
Sleeper cells hidden within the city were then activated and according to police, "neighbourhoods rallied to them".
[19] The group also bombed a police station in the neighborhood of al-Uraybi, and commandeered an abandoned building on the west of
Tigris river, transforming it into a headquarters for a group of thirty SWAT members.

On 9 June, ISIL executed fifteen Iraqi security force members who were captured in
Tikrit.
[25]According to
CBS News, ISIL fighters armed with machine guns and rocket-propelled grenades stormed the
Nineveh provincial headquarters that same day.
[26] By that time, the Fourth Battalion were among the very last local police fighting the attackers, the rest of the defense forces having run away or joined the opposition. Lacking plans and ammunition, Gharawi ordered the Iraqi military to retreat on the advice of retired general Khaled al-Obeidi.
[19] On that same night, ISIL and Sunni militants attacked Mosul, causing heavy fighting overnight.
Iraqi Army soldiers fled the city while it was under attack, allowing the militants to control much of Mosul by midday on 10 June.
[16] The militants seized numerous facilities, including
Mosul International Airport, which had served as a hub for the U.S. military in the region.
[27] Militants captured the
helicopters present at the airport, in addition to "several villages" and a military airbase in south
Saladin Province.
[26] The Iraqi army "crumbled in the face of the militant assault", which is evidenced by the fact that soldiers abandoned their weapons and dressed as civilians to blend in with the noncombatants.
[28]
The city fell to the ISIL on 10 June 2014 after four days of clashes between the insurgents and the Iraqi military. There were reports that the group was advancing from Mosul to
Kirkukat the time. While capturing the city, the group freed nearly 1,000 prisoners, some of whom were greeted by the fighters.
[9] Black flags were also flown over government buildings.
