Charge of the Light Brigade in the context of "The Charge of the Light Brigade (poem)"

Light cavalry comprised lightly armed and armored cavalry troops mounted on fast horses, as opposed to heavy cavalry, where the mounted riders (and sometimes the warhorses) were heavily armored. The purpose of light cavalry was primarily raiding, reconnaissance, screening, skirmishing, patrolling, and tactical communications. Prior to the 17th century they were usually armed with swords, spears, javelins, or bows, and later on with sabres, pistols, shotguns, or carbines.

Light cavalry was used infrequently by Ancient Greeks (who used hippeis such as prodromoi or sarissophoroi) and Ancient Romans (who used auxiliaries such as equites Numidarum or equites Maurorum), but were more common among the armies of Eastern Europe, North Africa, West Asia, Central Asia, and East Asia. The Arabs, Cossacks, Hungarians, Huns, Kalmycks, Mongols, Turks, Parthians, and Persians were all proficient horse archers.

Lieutenant-General James Thomas Brudenell, 7th Earl of Cardigan, KCB (16 October 1797 – 28 March 1868) was a British Army officer who commanded the Light Brigade during the Crimean War, leading its disastrous charge at the Battle of Balaclava. Throughout his life in politics and his long military career, Cardigan characterised the arrogant and extravagant aristocrat of the period. His progression through the British army was marked by many episodes of extraordinary incompetence, but also by generosity to the men under his command and genuine bravery. As a member of the aristocracy, he had actively and steadfastly opposed any political reform in Britain but, in the last year of his life, he relented and came to acknowledge that such reform would bring benefit to all classes of society.

Field Marshal FitzRoy James Henry Somerset, 1st Baron Raglan, GCB, PC (30 September 1788 – 28 June 1855), known before 1852 as Lord FitzRoy Somerset, was a British Army officer. When a junior officer, he served in the Peninsular War and the Waterloo campaign, latterly as military secretary to the Duke of Wellington. He also took part in politics as Tory Member of Parliament for Truro, before becoming Master-General of the Ordnance.

He became commander of the British troops sent to the Crimea in 1854: his primary objective was to defend Constantinople, and he was also ordered to besiege the Russian port of Sevastopol. After an early success at the Battle of the Alma, a failure to deliver orders with sufficient clarity caused the fateful Charge of the Light Brigade at the Battle of Balaclava. Despite further success at the Battle of Inkerman, a poorly coordinated allied assault on Sevastopol in June 1855 was a complete failure. Raglan died later that month, after having dysentery and depression.

Lewis Edward Nolan, known to his family as Louis Nolan and in Austrian service as Ludwig Nolan (4 January 1818 – 25 October 1854) was a British Army officer and cavalry tactician best known for his role and death in the Charge of the Light Brigade during the Crimean War. Born to an infantry officer and minor official and his wife, Nolan was educated at the Austrian Inhaber Pioneer School at Tulln, where he was noted as an enthusiastic horseman and military theorist. After early graduation he was commissioned as a subaltern in the 10th Austrian Hussar regiment, serving in Austria, Hungary and on the Polish frontier, where he again became known for his horsemanship and was promoted to senior lieutenant. Due to the nepotism in the Austro-Hungarian armed forces, Nolan transferred to the British Army as a cornet in the 15th Light Dragoons.

Deployed in India, Nolan was eventually made the regimental riding master and an aide-de-camp to General George Berkeley, commander-in-chief in Madras, accompanying him on horse trials to evaluate the use of geldings as cavalry mounts rather than stallions, and was made a captain in 1850. Returning to Great Britain in 1851, he toured continental Europe and wrote two books on horsemanship and cavalry theory, the second of which, Cavalry: Its History and Tactics, was universally acclaimed and led to the adoption of a Nolan-designed saddle by the British Army. A trusted voice on cavalry matters, Nolan was dispatched to the Middle East in the early days of the Crimean War to hunt for appropriate mounts. After returning he was attached to the staff of General Richard Airey, and in this role delivered the order that led to the Charge of the Light Brigade.
