Shirqat offensive (2016)

The Shirqat offensive, codenamed Operation Conquest or Operation Fatah, was an offensive against the positions of the Islamic State of Iraq and the Levant (ISIL) in and around the district of Al-Shirqat District to reach the city of Mosul.

The offensive was a joint effort by the Iraqi government forces with allied militias, local Assyrian Christian, Yezidi, Turcoman and Armenian militias, as well as Peshmerga and US and UK air support and limited ground forces. The aim of the operation, part of the military intervention against ISIL, was to set the conditions for an upcoming battle to push ISIL out of the second-largest city of Iraq, as well as the rest of the Nineveh Governorate. The operation followed the Mosul offensive in 2015, which successfully recaptured parts of the region northwest of Mosul, but stopped short of breaching the city itself, for various reasons.

Early in the morning of 21 October 2016, on the fifth day of the Mosul offensive, dozens of ISIL fighters assaulted the oil-rich city of Kirkuk, 175 kilometers (110 mi) from Mosul. After entering the city, ISIL members split up into groups of three to five fighters and spread out to five areas in the city after infiltrating on foot, and the battle lasted into the evening. By 22 October 2016, four of the five areas had been secured, with ISIL fighters remaining alive in the Dumez district. The strategy by Islamic State seems to have only been partially effective, as although it diverted media attention from the Mosul offensive, none of the forces used to repel the ISIL fighters came from the Mosul offensive.

June 2014
In June 2014, Islamic state fighters took control of the city of Mosul, Iraq's second- largest city, and the surrounding towns and villages. Civilians in Mosul and other areas in the province of Ninewa were swept up in the group's reign of terror. In October 2016, Iraq and Kurdish armed forces launched a military operation to retake Mosul. They recaptured territory in areas surrounding Mosul and several neighborhoods in the east of the city. Islamic state fighters have used civilians as human shields and carried out suicide bombings.

After the fall of Mosul to ISIL forces on 10 June 2014, the United States and the Iraqi Government made plans to retake the city. Initially, the plan called for an assault on Mosul in July or August 2015. From late January through early February 2015, the Peshmerga launched an offensive on northwest Mosul with 5,000 soldiers, cutting ISIL supply lines to Tal Afar, and coming within 10 kilometers (6 mi) of the city center, from Mosul's northwestern outskirts. In May 2015, the fall of Ramadi to ISIL delayed the planned offensive to retake Mosul to 2016. In late December, the Iraqi Army fully encircled Ramadi and launched another offensive to retake the city, fully recapturing Ramadi in December 2015 and the neighboring districts in February 2016. In late February 2016, 4,000 Iraqi soldiers redeployed to the Makhmour area in the southwestern Erbil Governorate, in preparation for an offensive on Mosul.

March
The offensive began on 24 March 2016, near the Makhmur area of Nineveh Governorate. Thousands of Iraqi troops had been deployed there in the previous weeks, setting up bases alongside Kurdish and US forces. While advancing westward toward the oil town of Qayyarah, Iraqi troops were reported to have recaptured several villages from ISIL, among them Al-Nasr, Garmandi, Kudila and Khurburdan, though it was later revealed that ISIL was still occupying Al-Nasr and the government forces were trying to capture it.

Around 4,000 soldiers, from two brigades of the U.S.-trained 15th Division of the Iraqi army, including Sunni tribal fighters (considered by Peshmerga commanders to be crucial to hold the traditionally Sunni areas), met stiff resistance. It was reported that they were attacked by suicide bombers as well as with mortars and machine guns, which stopped the advance for the time being. Warplanes of the U.S.-led coalition against ISIL launched multiple airstrikes on at least two locations. 200 U.S. Marines had set up a small outpost called Firebase Bell in the previous weeks. From there they provided artillery and targeting support for Iraqi forces. The presence of U.S. Marines became known after one of them was recently killed by the detonation of a roadside bomb. Kurdish Peshmerga forces didn't take an active part, contenting themselves with holding the front line at what they consider the border of their territory. It was announced on 27 March that Abu Furqan al-Misry, an ISIL commander and executioner who was a notorious figure in the region, had been killed.

During the offensive, Iraqi soldiers temporarily withdrew from the village of Nasr after ISIL started to shell the village, while Kurdish Peshmerga forces held their positions, according to Kurdish media. There were reports of 25 ISIL fighters killed as the Iraqi army shelled ISIL headquarters in Qayyarah.

American and Peshmerga forces fought back but the militants broke into the position using three truck bombs followed by bulldozers which cleared the wreckage away.
