The Raqqa campaign (codenamed Operation Wrath of Euphrates) was a military operation launched in November 2016 during the Rojava–Islamist conflict by the Syrian Democratic Forces (SDF) against the Islamic State (IS) in the Raqqa Governorate, with the goal of isolating and eventually capturing the Islamic State's capital city, Raqqa. The SDF's subsidiary goals included capturing the Tabqa Dam, the nearby city of al-Thawrah, and the Mansoura Dam further downstream. The campaign ended successfully in October 2017, with the capture of the city of Raqqa.
The offensive was concurrent with the Battle of Sirte in Libya, the Battle of Mosul in Iraq, the Battle of al-Bab in the Aleppo Governorate, the Palmyra offensive, the reignition of fighting in Deir ez-Zor's siege, the Central Syria campaign, and the Mayadin offensive.
Background
In late October 2016, the United States Secretary of Defense Ash Carter called for an offensive on Raqqa to take place concurrent with the Battle of Mosul in Iraq. He stated that the US was cooperating with its allies in order to launch an "isolation operation" around Raqqa. On 26 October, the President of Turkey Recep Tayyip Erdoğan called the President of the United States Barack Obama and stated that he did not want the People's Protection Units (YPG) to participate in the planned operation, and instead, planned to involve the Turkish Armed Forces. The United Kingdom's Secretary of State for Defence Michael Fallon rejected the idea of non-Arab forces taking part in the offensive and demanded a purely Arab force.
On the same day, the commander of the Combined Joint Task Force – Operation Inherent Resolve Lt. Gen. Stephen J. Townsend stressed that the YPG-led Syrian Democratic Forces was the only armed group capable of capturing Raqqa in the near future. Fewer US-led coalition troops were to be involved than in the Battle of Mosul. On 3 November, the commander of the Seljuk Brigade and SDF spokesman Col. Talal Silo rejected the participation of Turkey in the operation.
After the start of the Battle of Mosul, many of the 20,000 ISIL fighters estimated to be living in Mosul fled to Raqqa, boosting the ISIL forces that were already present in their de facto capital city.
Announcement
The SDF officially announced the start of the operation on 6 November 2016, in the city of Ayn Issa. The intention was to proceed in two phases, first seizing areas around Raqqa and isolating the city, advancing from three fronts, then taking control of the city itself. The SDF general command called for the international coalition against ISIL to support the operation. Secretary of Defense Ash Carter welcomed the announcement.
The offensive
Phase One: Isolating Raqqa from its northern hinterland
On 6 November, the SDF captured six small villages, Wahid, Umm Safa, Wasita, Haran, al-Adriyah and Jurah, south and southeast of Ayn Issa. The Islamic State detonated four car bombs on the first day of the offensive.
On 8 November, the SDF reported that they had taken control of 11 villages near Ayn Issa, and that the Islamic State forces used several car bombs against them. By 11 November, the SDF had captured over a dozen villages and the strategically significant town of Al-Hisbah, which had served as a local headquarters and command center for ISIL. On the next day, the SDF continued to advance against ISIL in the area around Tal Saman and Khnez, bringing the number of captured farms and villages to 26.
On 14 November, the SDF stated that 500 km2 has been captured, including 34 villages, 31 hamlets and seven strategic hills, and 167 Islamic State casualties had been inflicted. The SDF had also begun to besiege Tal Saman, the largest village and ISIL headquarters north of Raqqa, while ISIL launched a counter-attack near Salok in the eastern countryside of Raqqa Governorate in an attempt to force the SDF to split its forces and open a new front. On the next day, the SDF advanced into Tal Saman, resulting in a fierce battle with its ISIL defenders, and captured 10 more villages and farms. By 19 November, the SDF had fully captured Tal Saman and had driven ISIL completely from the surrounding countryside. With this, the first phase of the offensive was considered complete.
Stalemate and preparation for the second phase
The second phase of the offensive aimed to enforce a full blockade of the city of Raqqa. On 21 November, the SDF captured two more villages, while ISIL launched a counter-attack near Tal Saman. Over the next days, the SDF attempted to further advance, such as at al-Qalita, but was unable to break through ISIL's defense line south of Tal Saman. On 24 November, a US serviceman died from wounds he suffered after stepping on an improvised explosive device near the town of Ayn Issa, to the north of Raqqa.
On 25 November, ISIL received reinforcements from Iraq, among them explosive experts and defected Iraqi Army personnel. On the next day, ISIL launched a counter-attack, retaking parts of Qaltah village and a nearby water pump station, while the SDF managed to advance in the village's vicinity. Boubaker Al-Hakim, an ISIL commander who was linked to the Charlie Hebdo shooting, was reported to have been killed in an American airstrike in Raqqa on 26 November. Iraqi military however later stated in April 2017 that he might still be alive.
On 27 November, the SDF announced the offensive's second phase was due to start, though this was then delayed. At least five SDF fighters were killed in renewed clashes north of Raqqa on 29 November. Meanwhile, ISIL suffered from the defection of two senior commanders, who fled from Raqqa to join Jabhat Fateh al-Sham in Idlib. On 4 December, a coalition drone strike in Raqqa killed two ISIL leaders who had helped facilitate the November 2015 Paris attacks and another who was involved in a foiled suicide attack in Belgium in 2015. Three days later, co-Chair of the Democratic Union Party (PYD) Salih Muslim said that the first phase to surround Raqqa was almost over, while a new Arab brigade consisting of more than 1,000 men and women from the Raqqa area had joined the SDF as part of the second phase which was slated to be launched on 10 December. More than 1,500 Arab fighters who were trained and equipped by the anti-ISIL coalition joined the SDF for the second phase on its launch day.
Phase Two: Isolating Raqqa from its western countryside
Initial advances
The SDF launched the second phase on 10 December, with the aim of capturing the northwestern and western countryside of Raqqa and ultimately reaching and securing the Tabqa Dam. The same day, it was announced that Arab SDF groups, consisting of the Elite Forces, Jabhat Thuwar al-Raqqa and the newly formed Deir Ezzor Military Council would be taking part. During the first day, the SDF began to advance south of the Tishrin Dam and captured al-Kiradi village. The United States announced that it would send 200 more troops to assist the SDF. The next day, the SDF captured seven more villages from ISIL. On 12 December, the SDF captured four villages as well as many hamlets south of Tishrin Dam. The SDF captured five villages during the next two days. On 15 December, the SDF captured three villages, taking the total number of villages captured by them in the second phase to 20.
Over the next four days, the SDF captured 20 more villages and finally reaching Lake Assad, thereby cutting off and besieging 54 ISIL-held villages to the west. In response to these territorial losses, ISIL began to carry out more suicide attacks against both the SDF as well as civilian targets within SDF-controlled areas in an attempt to hinder the offensive. On 19 December, ISIL launched a counter-attack to regain four villages in the northwestern countryside, but the attack was repelled after a few hours. The SDF declared that they had captured 97 villages overall during the second phase, and had begun to advance against Qal'at Ja'bar.
Battle of Jabar
On 21 December, the SDF seized Jabar, which served as the main weaponry storage and supply centre for ISIL in the northwestern countryside. The coalition then began to move toward Suwaydiya Saghirah and Suwaydiya Kabir, the last villages before Tabqa Dam. Dozens of ISIS fighters launched counter-attack on Jabar village, confirmed killing 5 SDF fighters, among them a British volunteer, Ryan Lock. Jabar village soon recaptured after, the SDF attacked again on 23 December, and once again took control of it, while also capturing another village. This prompted ISIL to launch yet another counter-attack later that day, which was accompanied by several suicide car bombs. As a result, heavy clashes took place between them and SDF fighters in several villages along the frontline that lasted until the early morning of 24 December. The ISIL forces were eventually forced to withdraw after the SDF first shelled and then stormed their positions, whereupon the latter took control of most of Jabar as well as two more villages, though some ISIL holdouts persisted in Jabar.
ISIL was pushed out of the neighboring, strategic village of Eastern Jabar on the next day, bringing the SDF within 5 kilometres (3.1 mi) of Tabqa Dam, and by 26 December, the SDF had finally fully secured the main Jabar village, with the last ISIL defenders being expelled after heavy fighting. An ISIL counterattack on the village later that day failed, with a US airstrike killing Abu Jandal al-Kuwaiti as he commanded the assault. Al-Kuwaiti, also known as Abdulmuhsin al-Zaghelan al-Tarish, was a high-ranking ISIL commander leading the defense of the whole Raqqa region against the SDF. Meanwhile, the Amaq News Agency declared that Iman Na'im Tandil (nom de guerre: Abu 'Umar Al-Hindi), one of the few Indian ISIL fighters active in Syria, had also been killed during the fighting near Jabar. The Islamic State's official media wing later also officially paid tribute to Iman.
Battle for Jabar's surroundings
On 27 December, ISIL launched an attack on the village of Secol in the northern countryside, reportedly breaching the local SDF defences. On the next day, the SDF reportedly captured Hadaj village after two days of heavy fighting, while another ISIL counter-attack against Jabar was repelled. Mahmud al-Isawi, a senior ISIL manager of finances for the group's leaders who also worked in propaganda and intelligence-gathering, was killed on 31 December in a US-led coalition airstrike on Raqqa. After three days of heavy fighting, the SDF captured all or most of Mahmudli, the largest town of the Al-Jarniyah Subdistrict, on 1 January 2017. ISIL counterattacked later in an attempt to regain the town. The SDF leadership said that in the clashes since the launch of the second phase they had captured 110 villages, killed 277 ISIL fighters, and captured 13.
Also, on January 1, 2017, the SDF resumed its offensive on the northern front, advancing 6 km south of Tell Saman against ISIL positions. The SDF captured nine more villages in this area within the next three days. Meanwhile, with the SDF edging closer to Raqqa, ISIL further restricted Internet access and increased surveillance over Internet users in Raqqa. There were harsh punishments for accessing anti-ISIL websites, with a new special unit within the ISIL's security office searching for offenders. Several online activists in Raqqa were captured and tortured or executed.
Another two villages and hamlets were captured by the SDF on 5 January 2017.
The SDF captured Qal'at Ja'bar (Ja'bar Castle) from ISIL on 6 January. The same day, ISIL was reported to have moved its 150 prisoners from Tabqa city due to the offensive. The SDF later captured eight villages and five hamlets at the Ayn Issa front. On 7 January, the SDF captured five villages including the strategic Suwaydiya Gharbi and Suwaydiya Saghirah, reaching the outskirts of Tabqa Dam. ISIL recaptured Suwaydiya Saghirah by the next day after a counterattack, while a local leader of the group was killed in clashes. Meanwhile, ISIL was reported to have withdrawn 150 of its fighters towards Raqqa city.
On 8 January 2017, US special forces raided the village of Al-Kubar, between Raqqa and Deir ez-Zor, killing at least 25 ISIL militants in the two-hour operation. It was believed that the goal of the US may have been to rescue hostages from an ISIL secret prison in the village. After the raid, ISIL forces cut off access to the village.
On 9 January, the SDF captured another village, along with three hamlets.
