Shyrokyne standoff (February–July 2015)

Ukrainian forces, led by the Azov Battalion, launched an offensive to capture the village of Shyrokyne from pro-Russian separatists associated with the Donetsk People's Republic (DPR) on 10 February 2015. The village is located just 10 km from the Ukrainian-controlled city of Mariupol, and was used as a launching point for separatist attacks on that city, which is serving as the administrative centre of Donetsk Oblast whilst DPR forces control Donetsk city. Fighting continued until 3 July 2015, when DPR forces unilaterally withdrew from Shyrokyne.

Background
Mariupol had come under attack several times over the course of the War in Donbass, including in May–June 2014, when pro-Russian forces controlled the city, and in September 2014, when separatist forces tried to recapture the city prior to the signing of the Minsk Protocol. A separatist rocket attack, launched from the area around Shyrokyne on 24 January 2015, killed thirty civilians in Ukrainian-controlled Mariupol proper. Following this attack, Ukrainian forces, led by the Azov Battalion, began an offensive to stop the separatists from launching similar attacks.

Ukrainian offensive
Following the 24 January rocket attack, it became clear that Mariupol was vulnerable to further separatist attacks. Ukrainian forces said on 7 February that the DPR was massing forces for an attack on Mariupol. In response to these threats to the security of Mariupol, the National Guard of Ukraine, the Azov Battalion, and other Ukrainian volunteer groups launched an offensive to the east of the city, along the coast of the Azov Sea, toward Novoazovsk, on 10 February. The Ukrainian government said that the offensive was intended to eliminate insurgent positions near Mariupol, so as to stop shelling, and to regain positions demarcated as Ukrainian under the Minsk Protocol. Azov Battalion members, on the other hand, said that the goal of the offensive was to retake Novoazovsk, which had been under DPR control since a battle there in August 2014.

The new Ukrainian offensive outside Mariupol came as DPR and LPR forces were assaulting the strategic town of Debaltseve, 200 km to the north. Accordingly, the offensive was also intended to relieve pressure on Debaltseve by forcing the insurgents divert manpower and weaponry to the southern part of the line of contact. After breaking through DPR lines, the Azov Battalion managed to quickly capture the towns of Shyrokyne, Pavlopil, and Kominternove, and began to advance toward Novoazovsk. According to the battalion, Ukrainian flags were raised in Shyrokyne, Pavlopil and Oktyabr. Ukrainian forces pushed the separatists back to Sakhanka, about 7 km north-east of Shyrokyne, where DPR forces held the line. Ukrainian and DPR forces continued to fight at Sakhanka on 11 February, as Ukrainian forces led by the Azov Battalion attempted to secure the village. According to Ukrainian president Petro Poroshenko, the advance by Ukrainian forces into Sakhanka "moved the frontline to correspond exactly to the Minsk memorandum as a result of the counter-offensive".

Shyrokyne was heavily bombarded by DPR artillery on 12 February. According to the Azov Battalion, the separatists had launched an all-out counter-offensive to curtail the Ukrainian advance, deploying tanks and artillery. Ukrainian forces suffered heavy losses amidst the bombardment, and the Battalion said that "Shyrokyne has been virtually wiped out" by the artillery fire. Subsequently, the Azov Battalion was forced to retreat from Sakhanka to Shyrokyne, leaving it under DPR control. Due to the fighting in area around Shyrokyne, local emergency authorities evacuated all civilians from the Ukrainian government-controlled parts of Novoazovsk Raion to Mariupol.

Minsk II
A new ceasefire agreement, called Minsk II, was signed on 12 February. According to the agreement, a total ceasefire across the Donbass was to begin at midnight on 15 February. Despite this, five Ukrainian soldiers were killed and twenty-two were wounded in a DPR attack at Shyrokyne on 16 February. By the 21st of February, the Ukrainian government said that separatist forces were once again massing for a new offensive on Mariupol. NSDC spokesman Andriy Lysenko said that DPR forces were "conducting sabotage and intelligence operations round the clock to test government defences" in the area around Shyrokyne. DPR forces in Sakhanka had dug in, whilst those in and Bezimenne had established a base of operations in some houses there. Ukrainian officials said that Russia had sent tanks and soldiers toward Novoazovsk to reinforce the DPR, and a Reuters team said it saw men who "looked like Russian military special forces wearing Russian army patches and insignia on their uniforms" at Bezimenne.

DPR forces recaptured the villages of Pavlopil and Pyshchevyk on 25 February. According to a Ukrainian official, these villages were in the buffer zone established by Minsk II, and hence had not been occupied by Ukrainian forces. Sporadic fighting continued in the Shyrokyne area, and The Guardian reported exchanges of artillery and machine gun fire. A local commander of the Donbas Battalion said that his forces had engaged the separatists, destroying an anti-aircraft gun and a petrol tanker. In addition, Ukrainian soldiers began to build a second defensive line in the adjacent village of Berdyanske, which lies just to the west of Shyrokyne. Continued concerns about a potential separatist offensive on Mariupol were bolstered by a report on 27 February that said that DPR heavy weaponry had been seen leaving Donetsk in the direction of Mariupol. Sporadic exchanges of fire continued over the next few days. The next major outbreak of fighting occurred on 9 March, when Ukrainian forces said that the DPR had launched a hail of tank and mortar fire onto Ukrainian positions in Shyrokyne. They said that the DPR was attempting to "force Ukrainian contingents from Shyrokyne". Whilst Ukrainian troops continued to hold the line, DPR forces managed to gain control of about 30 percent of the village by 21 March. By the end of the month, between 50 and 60 percent of Shyrokyne had been destroyed in the fighting.

On 5 April, a landmine exploded under a military vehicle at Shyrokyne killing two soldiers and injuring a third, a military spokesman said on the TV channel 112.

On 13 April, it was confirmed the separatists had captured the village of Vodyane, seven kilometers east of Mariupol, after it was in the middle of a no man's land for almost a month following a retreat by government troops. The next day, a Russian journalist was injured by a landmine in Skyrokyne during a tour as some of the heaviest fighting since February erupted. By 16 April, separatists were in control of much of Shyrokyne.

On 18 April, a Georgian member of the Azov Battalion was killed in fighting near Shyrokyne.

In late April, Deutsche Welle reported that pro-Russian militants had set up positions in the centre of Shyrokyne and that the OSCE and Red Cross were not always granted access. On 26 April, the OSCE observed what it assessed to be the most intense shelling in Shyrokyne since February.

On 5 May, 12 hours of sustained separatist attacks in Shyrokyne against Ukrainian positions near the beach took place, after a one-hour tank assault was launched, followed by constant firefights.

In mid-June, as the Ukrainian president visited government lines at Mariupol, more fighting near Shyrokyne left one soldier dead and two wounded.

Separatist withdrawal
On 1 July, separatist forces proclaimed Shyrokyne to be a demilitarized zone and withdrew from the village. Denis Pushilin, the self-declared Chairman of the Supreme Soviet of Donetsk People's Republic, stated that the decision to withdraw forces from Shyrokyne was made "as an act of good will and the demonstration of peaceful intentions." On 3 July, the Ukrainian government confirmed the separatists had withdrawn from the village. According to Andriy Biletsky, commander of Ukraine's Azov Battalion which launched the offensive to seize the village in February 2015, the DNR's decision to leave was not due to their willingness to follow the Minsk agreement but due to the heavy casualties suffered by the separatists while battling to hold the village. OSCE observers confirmed areas of the village previously held by the "DNR" had been vacated, stating they "observed no armed formation in the village, except for some Ukrainian Armed Forces positions at the village's south-western edge."

As of 7 July, nether side controlled Shyrokyne as the Azov Battalion was holding positions on a nearby hill, while the separatists pulled back to another hill outside the village. Ukrainian fighters associated with the Right Sector group said that they would ignore any order to withdraw from the village, despite calls for it to become a demilitarised zone. A local Right Sector commander said that a withdrawal from Shyrokyne would expose Mariupol to attack, and that "only enemies of Ukraine can give an order to withdraw".

On 29 July the volunteer battalions Azov and Donbass left their positions at the village and were replaced with a unit of active duty marines. The decision to pull out Donbass battalion from Shyrokyne was met with protests from residents of Mariupol, who feared that the withdrawal would lead to Russian separatists quickly retaking the village and once again begin shelling the city.
