The regiment arrived at Stirling Castle in October 1848 and provided a Guard of Honour for Queen Victoria on her visit to Glasgow in August 1849. It embarked for the Crimea for service in the Crimean War in February 1854. As part of Brigadier-General Colin Campbell's Highland Brigade, it took part in the Battle of Alma in September 1854. On 25 October 1854, it was stationed outside the British-controlled port of Balaklava as part of its very thin defences. The Russian Army sent a large force to attack Balaklava, precipitating the Battle of Balaclava. The Russian threat was countered in part by the charge of General James Scarlett's Heavy Cavalry Brigade but the rest of the Russian force headed straight for the 93rd Regiment of Foot.
