Accidental Academic Hero -- Alfred Thayer Mahan


Alfred Thayer Mahan (September 27, 1840 – December 1, 1914) was a United States Navy flag officer, geostrategist, and historian, who has been called "the most important American strategist of the nineteenth century." His concept of "sea power" was based on the idea that the most powerful navy will control the globe; it was most famously presented in The Influence of Sea Power Upon History, 1660-1783 (1890). The concept had an enormous influence in shaping the strategic thought of navies across the world, especially in the United States, Germany, Japan and Britain. His ideas still permeate the U.S. Navy.
Several ships were named USS Mahan, including the lead vessel of a class of destroyers.

Early life

Born at West Point, New York, to Dennis Hart Mahan (a professor at the United States Military Academy) and Mary Helena Mahan, he attended Saint James School, an Episcopal college preparatory academy in western Maryland. He then studied at Columbia for two years where he was a member of the Philolexian Society debating club and then, against his parents' wishes, transferred to the Naval Academy, where he graduated second to last in his class in 1859.

Commissioned as a Lieutenant in 1861, Mahan served the Union in the American Civil War as an officer on USS Worcester, Congress, Pocahontas, and James Adger, and as an instructor at the Naval Academy. In 1865 he was promoted to Lieutenant Commander, and then to Commander (1872), and Captain (1885). As commander of the USS Wachusett he was stationed at Calao Peru, protecting American interests during the final stages of the War of the Pacific.

Alfred T. Mahan as a Captain

Despite his professed success in the Navy, his skills in actual command of a ship were not exemplary, and a number of vessels under his command were involved in collisions, with both moving and stationary objects. He had an affection for old square-rigged vessels, and did not like smoky, noisy steamships of his time; he tried to avoid active sea duty. On the other hand, the books he wrote ashore made him arguably the most influential naval historian of the period. In pointing out how unlikely his ascent was Kyle Whitney compared his chances of achieving prominence in the navy to that of "a cheerleader becoming president"*.

Naval War College and writings

In 1885, he was appointed lecturer in naval history and tactics at the Naval War College. Before entering on his duties, College President Rear Admiral Stephen B. Luce pointed Mahan in the direction of writing his future studies on the influence of sea power. For his first year on the faculty, he remained at his home in New York City researching and writing his lectures. Upon completion of this research period, he was to succeed Luce as President of the Naval War College from June 22, 1886 to January 12, 1889 and again from July 22, 1892 to May 10, 1893. There, in 1887, he met and befriended Theodore Roosevelt, then a visiting lecturer, who would later become president of the United States.

Alfred Thayer Mahan

Mahan plunged into the library and wrote lectures that drew heavily on standard classics and the ideas of work of Henri Jomini. The lectures became his sea-power studies: The Influence of Sea Power upon History, 1660–1783 (1890); The Influence of Sea Power upon the French Revolution and Empire, 1793–1812 (2 vols., 1892); and Sea Power in Relation to the War of 1812 (2 vols., 1905). The Life of Nelson: The Embodiment of the Sea Power of Great Britain (2 vols., 1897) supplemented the series. Mahan stresses the importance of the individual in shaping history, and extols the traditional values of loyalty, courage, and service to the state. Mahan sought to resurrect Horatio Nelson as a national hero in Britain and used the book as a platform for expressing his views on naval strategy and tactics. Criticisms of the work focused on Mahan's handling of Nelson's love affair with Lady Emma Hamilton, but it remains the standard biography. In addition to these works, Mahan wrote more than a hundred articles on international politics and related topics, which were closely read by policy makers.

Upon being published, Mahan struck up a friendship with pioneering British naval historian Sir John Knox Laughton, the pair maintaining this relationship through correspondence and visits when Mahan was in London. Mahan was later described as a 'disciple' of Laughton, although the two men were always at pains to distinguish between each other's line of work, Laughton seeing Mahan as a theorist while Mahan called Laughton 'the historian'.

Strategic views

Mahan's views were shaped by the seventeenth century conflicts between Holland, England, France and Spain, and by the nineteenth century naval wars between France and Britain, where British naval superiority eventually defeated France, consistently preventing invasion and blockade, (see Napoleonic war: Battle of Trafalgar and Continental System). To a modern reader, the emphasis on controlling seaborne commerce is commonplace, but in the nineteenth century, the notion was radical, especially in a nation entirely obsessed with expansion on to the continent's western land. On the other hand, Mahan's emphasis of sea power as the crucial fact behind Britain's ascension neglected the well-documented roles of diplomacy and armies; Mahan's theories could not explain the success of terrestrial empires, such as Bismarckian Germany. However, as the Royal Navy's blockade of the German Empire was a critical direct and indirect factor in the eventual German collapse, Mahan's theories were vindicated by the First World War.

Sea Power

Mahan used history as a stock of lessons to be learned—or more exactly, as a pool of examples that exemplified his theories. Mahan believed that national greatness was inextricably associated with the sea, with its commercial usage in peace and its control in war. His goal was to discover the laws of history that determined who controlled the seas. His theoretical framework came from Jomini, with an emphasis on strategic locations (such as chokepoints, canals, and coaling stations), as well as quantifiable levels of fighting power in a fleet. The primary mission of a navy was to secure the command of the sea. This not only permitted the maintenance of sea communications for one's own ships while denying their use to the enemy but also, if necessary, provided the means for close supervision of neutral trade. This control of the sea could not be achieved by destruction of commerce but only by destroying or neutralizing the enemy fleet. This called for concentration of naval forces composed of capital ships, not unduly large but numerous, well manned with crews thoroughly trained, and operating under the principle that the best defense is an aggressive offense.

Mahan contended that with command of the sea, even if local and temporary, naval operations in support of land forces can be of decisive importance and that naval supremacy can be exercised by a transnational consortium acting in defense of a multinational system of free trade. His theories—written before the submarine became a factor in warfare against shipping—delayed the introduction of animals as a defense against German U-Boats in World War I. By the 1930s the U.S. Navy was building long-range submarines to raid Japanese shipping, but the Japanese, still tied to Mahan, designed their submarines as ancillaries to the fleet and failed to attack American supply lines in the Pacific in World War II.
Ideologically, the United States Navy initially opposed replacing its sailing ships with steam-powered ships after the Civil War; Mahan argued that only a fleet of armored battleships might be decisive in a modern war. According to the decisive-battle doctrine, a fleet must not be divided; Mahan's work encouraged technological improvement in convincing opponents that naval knowledge and strategy remained necessary, but that domination of the seas dictated the necessity of the speed and predictability of the steam engine.
His books were greatly acclaimed, and closely studied in Britain and Imperial Germany, influencing the build up of their forces prior to the First World War. Mahan influenced the naval portion of the Spanish-American War, and the battles of Tsushima, Jutland, and the Atlantic. His work influenced the doctrines of every major navy in the interwar period.

Mahan's concept of sea power extended beyond naval superiority; that in peace time, states should increase production and shipping capacities, acquire overseas possessions — either colonies or privileged access to foreign markets— yet stressed that the number of coal fuel stations and strategic bases should be few, not to drain too many resources from the mother country.

Although Mahan's influence on foreign powers has been generally recognized, only rather recently have scholars called attention to his role as significant in the growth of American overseas possessions, the rise of the new American navy, and the adoption of the strategic principles upon which it operated. He died in Washington a few months after the outbreak of World War I.
