In early September, Soviet and Romanian forces entered Transylvania and captured the towns of Brașov and Sibiu while advancing toward the Mureș River. Their main objective was Cluj (Cluj-Napoca), a city regarded as the historical capital of Transylvania. However, the Second Hungarian Army was present in the region, and together with the Eighth German Army engaged the Allied forces on 5 September in what was to become the Battle of Turda, which lasted until 8 October and resulted in heavy casualties for both sides. Also around this time, the Hungarian Army carried out its last independent offensive action of the war, penetrating Arad County in western Romania. Despite initial success, a number of ad hoc Romanian cadet battalions managed to stop the Hungarian advance at the Battle of Păuliș, and soon a combined Romanian-Soviet counterattack overwhelmed the Hungarians, who gave ground and evacuated Arad itself on 21 September.
