A large Russian assault on the allied supply base to the southeast, at Balaclava was rebuffed on 25 October 1854.:521527 The Battle of Balaclava is remembered in the UK for the actions of two British units. At the start of the battle, a large body of Russian cavalry charged the 93rd Highlanders, who were posted north of the village of Kadikoi. Commanding them was Sir Colin Campbell. Rather than 'form square', the traditional method of repelling cavalry, Campbell took the risky decision to have his Highlanders form a single line, two men deep. Campbell had seen the effectiveness of the new Minie rifles, with which his troops were armed, at the Battle of the Alma a month before, and was confident his men could beat back the Russians. His tactics succeeded. From up on the ridge to the west, Times correspondent William Howard Russell saw the Highlanders as a 'thin red streak topped with steel', a phrase which soon became the 'Thin Red Line.'

Who did the Russians attack at the beginning off the Battle of Balaclava?
