The Battle of Tskhinvali was a fight for the city of Tskhinvali, capital of South Ossetia. It was the only major battle in the 2008 South Ossetia War. Georgian ground troops entered the city on early 8 August 2008, after an extensive artillery barrage. Their advance was stopped by South Ossetian militia and members of the Russian peacekeeping force stationed in the city. Later that day, Russian combat troops arrived to South Ossetia through the Roki tunnel. After being initially forced to withdraw, the Georgian troops made several attempts to retake the city. Due to the difficult logistics of the terrain, the arrival of Russian reinforcements was slow. After fierce fighting, Georgian troops were finally forced to withdraw from the city on the evening of 10 August. On 11 August, all Georgian troops left South Ossetia. Parts of Tskhinvali were devastated in the three-day fighting.
