Fights on the Ukrainian–Russian border (2014)

Fights on the Ukrainian–Russian border in 2014, also famous as "Operation to restore the state border", "Battle at the border",   Battle in sector D , (in Russian-language sources often – "Izvarinsky Encirclement",  "Dovzhansky Encirclement"  ) – an episode of the war in eastern Ukraine, the battle of anti-terrorist operation forces against illegal armed groups supported by Russian artillery in the border areas of Donetsk and Luhansk regions during summer campaign in Donbass. Fighting broke out in Sector D of the anti-terrorist operation during the "operation to restore the state border" during June–August 2014. The main task of the Anti-Terrorist Operation Forces was to restore control over the section of the state border Izvaryne – Kumachovo and to cut the routes for illegal armed groups.

Establishing border control was a key point in the peace plan of newly elected President Petro Poroshenko. The offensive of the anti-terrorist operation forces began on 12 June. During the confrontation, Ukrainian units came under artillery fire from the territory of the Russian Federation. During numerous battles, the Ukrainian military failed to regain control of the Izvaryne checkpoint. With the loss of control over the settlements of Stepanovka, Marynivka and the Marynivka checkpoint in mid-July, anti-terrorist operation forces east of the village of Marynivka found themselves in an actual environment of the main forces. The besieged units were unblocked and in fact the battle ended on 7 August with the release of the last units that performed the task of blocking the state border. The battle on the border was the first major defeat for the anti-terrorist operation forces. As a result, control over the state border from Izvaryny to Marynivka was lost. The Armed Forces, the National Guard and the State Border Guard Service of Ukraine have suffered heavy losses in both personnel and equipment. The Armed Forces of Ukraine suffered particularly heavy losses.

Fighting at the border significantly limited the ability to supply from Russia, and after capturing hundreds of kilometers of the state border, the ability to supply militants, equipment and ammunition from Russia was limited only by its own available resources. As the supply of militants came exclusively from Russia, border control was a key point of settlement and later became one of the foundations of the Minsk Protocol.

The situation in early summer
Incidents of violation of the state border began in the spring of 2014. So in the beginning of April a group of mercenaries from the Russian Federation led by a citizen of the Russian Federation, a former employee of special services, Igor Girkin freely entered the territory of Ukraine and captured the city of Slovyansk. At the end of May, it became quite clear that the state border was not locked. From Russia, militant detachments, military equipment and supplies arrived in Donetsk and Luhansk oblasts without hindrance. The leadership of the border service reported full control over the state border. But the actual state of affairs was criticized by the leadership of the State Border Guard Service of Ukraine, in particular the head of the State Border Guard Service of Ukraine Mykola Lytvyn.

So, on the night of 2–3 May 2014, two Ural trucks loaded with weapons drove into the yard of the Antratsyt District State Administration. The administration's premises were occupied by several dozen Don Cossacks, they did not let anyone into the yard, did not answer questions. The Russian flag and the flag of the Don Army were raised above the administration.

Another high-profile incident occurred on 13 May, when the wounded self-proclaimed Luhansk "governor" Valery Bolotov was able to leave Ukraine through the Dovzhansky checkpoint. Acting President of Ukraine and Speaker of the Verkhovna Rada Oleksandr Turchynov instructed the Prosecutor General's Office and the Security Service of Ukraine to explain the reasons for this withdrawal within three hours. On 17 May, border guards detained Valery Bolotov at the Dovzhansky checkpoint at 5:45 am, informed all law enforcement agencies, including representatives of the anti-terrorist operation, and waited for about two hours for help from security forces, but no one arrived. Clashes broke out between the militants and border guards, as a result of which Bolotov was repulsed by armed men.

On 19 May 2014, a group of pro-Russian militants (about 50 people) carried out an armed attack on a checkpoint of the Armed Forces of Ukraine near the town of Amvrosiyivka, Donetsk region, near the Uspenka border checkpoint. As a result of the confrontation, the militants were neutralized, and some of them were detained and prosecuted. On 27 May, an air strike destroyed a terrorist training camp at the Yaseni camp near Sverdlovsk. However, at the time of the attack, most of the terrorists had moved to Sverdlovsk.

On 1 June, head of the border service Mykola Lytvyn admitted that militants, including Russian citizens, were breaking through the state border every day. They tried to block the border guards. The SBGS moved from guarding to defending the border. On 30 May, a column of militants was stopped and five militants were killed. Since the beginning of March, more than 250 Russian citizens have been detained trying to travel to Ukraine for sabotage. In early June, there were a number of armed clashes between the State Border Guard Service of Ukraine and militants seeking to establish their control over the border.

On 28 May, the airspace of Ukraine was violated by the Russian Federation, and the flight of a Russian UAV was recorded in the anti-terrorist operation zone. On 30 May, border guards in the direction of Novaya Nadezhda (Russia) – Dibrivka (Ukraine) detained armed individuals with a significant number of weapons while attempting to enter illegally. On 2 June, border guards were attacked. Fights with militants took place near Horodyshche and Amvrosiivka. On 3 June, after a two-day assault, the Luhansk border detachment was captured. The attack on the Luhansk border detachment was a planned action aimed at disorganizing the actions of border guards to protect the border with Russia. After the loss of control, the border guards were left without a coordinating and governing body. On the night of 3–4 June, and in the first half of 4 June, a special operation was conducted to relocate SBGS personnel in the Luhansk region. During the movement, on 3–4 June, a column of border guards was attacked, three assailants were killed and one car was destroyed. Personnel, weapons, ammunition, and equipment from the Stanychno-Luhanske, Krasnodon, Biryukovo, Sverdlovsk, and Dyakovo Luhansk Oblast Border Service were redeployed. Many weapons were left in Sverdlovsk. The SBGS stressed the need to involve the National Guard and the Armed Forces to defend the state border.

On 5 June, a battle took place for the Marynivka checkpoint, which was attacked by terrorists from the Vostok group. A convoy of militants, consisting of an armoured personnel carrier, four Kamaz trucks, three minibuses, and four cars invading from Russia, attacked the border checkpoint. Thanks to the reinforcements that arrived on time, the battle for the anti-terrorist operation forces was victorious. The militants retreated to Russian territory. During the battle, the armoured personnel carriers of the militants were captured.

During 4–5 June, there were attempts to oust border detachments from checkpoints, and on 5 June, according to a government decision, Ukraine closed 8 border checkpoints, which was officially reported to the Russian authorities: in Luhansk region – Chervonopartizansk, Dovzhansky, Chervona Mohyla, Novoborovtsi, Krasnodarskyi(checkpoint in the adjacent territory – Donetsk), Krasnodarskyi (checkpoint in the adjacent territory – Nizhny Shvyrev)," Northern "; in the Donetsk region – "Marynivka". Thus, about 100 km of the border was left unguarded. On 7 June, the Ministry of Foreign Affairs of Ukraine handed Russia a note of protest against violations of the regime at the border. The note listed the facts of violations and drew attention to the participation in the conflict of Russian paramilitary group – "Kazaki".

On 7 June, the militants issued an ultimatum to border guards at the Izvaryne checkpoint and demanded that they leave the checkpoint by evening.

On 8 June, militants attacked the Izvarine checkpoint. Border guards successfully repulsed the attack. On 10 June, militants seized the Dovzhansky checkpoint. On 12 June, tanks were transferred to Ukraine from the Russian Federation, crossing the border at night, passing through Snizhne, Torez, and Makiivka, and entering Donetsk. In the evening of 12 June, Poroshenko held a meeting with the heads of law enforcement agencies on the invasion of tanks of the Russian Federation.

Plan for future operations
The decision to conduct an operation to restore border control was made for both political and purely military reasons. Border control and the creation of a 10 km buffer zone was one of the key points of the peace plan proposed by newly elected President Petro Poroshenko. Later, Secretary of the National Security and Defense Council Andriy Parubiy said that the state border was closed in accordance with the task set by the President. Later in an interview, the former chief of staff of the anti-terrorist operation, General Viktor Nazarov, said that the corridor along the border of the anti-terrorist operation was punched to meet the requirements of the European community. This was one of the requirements for assistance to Ukraine. According to Nazarov, the Ukrainian military command was not very happy about this, because it understood that their men were in fact exposed to fire from two sides.

The initial task of the anti-terrorist operation group was to isolate the anti-terrorist operation area, regain control of the 140-kilometer section of Ukraine's state border with the Russian Federation on the Izvaryne-Kumachyovo section to prevent the groups of Russian mercenaries from crossing the border and eliminate militant and separatist lines, weapons and ammunition. In addition, the grouping of Sector "D" was entrusted with the task of ensuring the unimpeded transportation of ammunition and logistics between Petrovske – Stepanovka.

Border control was to make it impossible for the militants to use the five main routes through which the militant-controlled territories were connected with the Russian Federation, specifically the Uspenka, Marynivka, Dovzhansky, Chervonopartizansk and Izvaryne. Plans included creating fortified defense points, which could destroy the enemy moving through highways and steppe areas with artillery fire.

Moreover, after performing the first task (blocking the state border), the brigades of the Armed Forces had to move to the second – the encircling the megacities. Territorial defense battalions were to take their place. The operation was scheduled to begin on 17 May, but had to be postponed due to an attack on a 51st mechanized brigade checkpoint near Volnovakha, as a result of which the demoralized unit was temporarily withdrawn to the rear. In fact, the offensive did not begin until 12 June. This postponement allowed the militants to strengthen their positions in the border zone. On 5 June, militants from Donetsk and Shakhtarsk arrived in Amvrosiivka, numbering several hundred people with several armored personnel carriers and about ten trucks. On the same day, five trucks with Caucasian-looking militants arrived in Snizhne.

On 7 June, a column of militants from Russia invaded Ukraine. Part of the column went to Torez and Snizhne. From Snizhne, the militants began to establish a stronghold and prepare for the siege. During 8 June, the militants continued fortification work in Snizhne: set up checkpoints, dug trenches, and equipped firing points. The columns brought reinforcements from Russia, including Russian military personnel.

In Snizhne on 10 June, the number of DPR militants, including militants of the Vostok group, increased. The strengthening of barricades and preparations for defense also continued. Dmytrivka was already under militant control. Snizhne would be a key settlements in future battles on the border, 15 km to the Ukrainian-Russian border and 12 km to the Savur-Mohyla hill – the highest point in the area. It would be difficult to keep Savur-Mohyla without control on Snizhny.

In the morning of 11 July 2014, as a result of unexpected massive artillery attacks on military parts in the area of Zelenopoly, 30 were killed and more than 100 soldiers were injured. During the next few days and weeks after the attack, the attack near the border are located at the border of the units subjected to dozens of artillery strikes.

There were suspicions that the shelling was held from the territory of Russia. British journalists argue that a place from which a blow to be found in the Matvian-Kurgan district of the Rostov region of the Russian Federation near the Ukrainian-Russian border.
