The Battle of Balaclava opened on October 25, 1854, on the Crimean peninsula. British, French, and Ottoman forces were besieging the Russian naval base at Sevastopol, and the Russians struck to cut their supply line. The day held three actions, but one stands out.
The Light Brigade was a unit of around 670 British cavalry. Lord Raglan, the army commander, wanted them to stop the Russians from carrying off captured guns. His order passed through two officers and came out wrong. Lord Cardigan led the brigade down a valley lined with artillery on both sides. They rode straight into fire.
Russian guns at the valley mouth and on the heights to the right and left tore the line apart, yet the horsemen pushed to the battery and sabred the gunners before turning back through the same guns. Of the roughly 670 who started, about 110 were killed and more than 300 horses were lost. The survivors rode back under fire. The blunder was plain.
Captain Nolan, who carried the order, was killed early, and no officer with authority corrected the mistake in time. Tennyson's poem "The Charge of the Light Brigade" fixed the day in memory as a tale of duty done without asking why. The war went on. Balaclava showed the risk of unclear orders in the age of the telegraph and the rail, where messages moved faster than the men who received them.
