First published in 1853, Cavalry: Its History and Tactics had a major impact on military theorists and officers for decades—it was reprinted as a manual during the American Civil War—and its influence on European cavalry performance can be traced into World War I. It is an intelligent work which discusses the history and development of cavalry over the ages, advocates a program of reform for Britain's horsed troops, and covers many aspects of equipment, training, drill, organization, formation, and battlefield tactics. The author, an experienced and gifted cavalryman, first served in the Austrian army, then joined the British army's 15th Hussars in 1839, fought in India, and became the regimental riding master. Captain Nolan's 1852 tour of European armies, wide reading in many languages, and service in Europe and India makes Cavalry an extraordinary statement on mid-nineteenth-century theory and practice.As historian Jon Coulston explains in his introduction, Nolan was writing at the cusp of technological change, drawing upon the experiences of the Napoleonic Wars, continental suppression of the 1848 Revolutions, and Britain's wars in India, but with an eye to firepower developments on the eve of the Crimean War. In 1854, at the Battle of Balaklava, Nolan rode with the written order which unleashed the Charge of the Light Brigade, an action in which he lost his life.   Presented here as the first modern reprint, completely retypeset and with a new introduction and further reading by historian Jon Coulston, Nolan's Cavalry remains a hallmark of military history.
