Battle of Ilovaisk
The Battle of Ilovaisk started on 7 August 2014, when the Armed Forces of Ukraine and pro-Ukrainian paramilitaries began a series of attempts to capture the city of Ilovaisk from pro-Russian insurgents affiliated with the Donetsk People's Republic (DPR) and detachments of the Russian Armed Forces. Although Ukrainian forces were able to enter the city on 18 August, they were encircled between 24 and 26 August by overwhelming Russian military forces that crossed the border, joining the battle.
