Lewis Edward Nolan, known to his family as Louis Nolan and in Austrian service as Ludwig Nolan 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 a 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.

The Charge of the Light Brigade was a military action undertaken by British light cavalry against Russian forces during the Battle of Balaclava in the Crimean War, resulting in many casualties to the cavalry. On 25 October 1854, the Light Brigade, led by Lord Cardigan, mounted a frontal assault against a Russian artillery battery which was well prepared with excellent fields of defensive fire. The charge was the result of a misunderstood order from the commander in chief, Lord Raglan, who had intended the Light Brigade to attack a different objective for which light cavalry was better suited, to prevent the Russians from removing captured guns from overrun Turkish positions. The Light Brigade made its charge under withering direct fire and reached its target, scattering some of the gunners, but was forced to retreat immediately.
