The "Division", which now consisted of the Guards Brigade and the Highland Brigade, was involved in the Battle of Alma (20 September 1854), which is considered to be the first battle of the Crimean war. They were next in action during the Battle of Balaclava. The battle started with a successful Russian attack on Ottoman positions. This led to the Russians breaking through into the valley of Balaklava (anglicised as "Balaclava"), where British forces were encamped. The Russian advance was intended to disrupt the British base and attack British positions near Sevastopol from the rear. An initial Russian advance south of the southern line of hills was repulsed by the British. A large attacking force of Russian cavalry advanced over the ridgeline, and split into two portions. One of these columns drove south towards the town of Balaklava itself, threatening the main supply of the entire British army. That drive was repulsed by the muskets of the 93rd (Highland) Regiment, which had been formed into a lone line of two rows by its commander, Sir Colin Campbell. This action became known in history as "The Thin Red Line", this battle was also well known for the Charge of the Light Brigade. The division was also involved in the Battle of Inkerman (5 November 1854).
