Alfred Thayer Mahan
Alfred Thayer Mahan was a United States Navy officer and historian whom John Keegan called "the most important American strategist of the nineteenth century." His 1890 book The Influence of Sea Power upon History, 1660–1783 won immediate recognition, especially in Europe, and with the publication of its 1892 successor, The Influence of Sea Power upon the French Revolution and Empire, 1793–1812, he affirmed his status as a globally-known and regarded military strategist, historian, and theorist. Mahan's works encouraged the development of large capital ships—eventually leading to dreadnought battleships—as he was an advocate of the 'decisive battle' and of naval blockades.
Critics, however, charged him with failing to adequately explain the rise of largely land-based empires, such as the German or Ottoman Empires, though Mahan did accurately predict both empires' defeats in World War I. Mahan directly influenced the dominant interwar period and World War II-era Japanese naval doctrine of the "decisive battle doctrine", and he became a "household name" in Germany. He also promoted American control over Hawaii though he was "lukewarm" in regard to American imperialism in general. The USN's Mahan-class of destroyers served as his namesake, four individual USN ships have borne his name, as well as various buildings and roads.
Mahan has been described as "America's first globalist" and the United States Naval Institute has described his scholarship as "foundational to all systematic study of naval power". Strategies and ideas which view Mahan's works as key are sometimes referred to as "Mahanian", with adherents referred to as "Mahanians".
Early life
Mahan was born on September 27, 1840, at West Point, New York, to Dennis Hart Mahan, a professor at the United States Military Academy and the foremost American expert on fortifications, and Mary Helena Okill Mahan, daughter of John Okill and Mary Jay, daughter of Sir James Jay. Mahan's paternal grandparents, John Mahan and Mary Mahan, were Irish immigrants. Mahan's middle name honors "the father of West Point", Sylvanus Thayer. Mahan 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. Against the wishes of his father, Mahan then entered the U.S. Naval Academy, where he graduated second in his class in 1859.Early career
After graduation he was assigned to the frigate from 9 June 1859 until 1861. He then joined the steam-corvette of the South Atlantic Blockading Squadron and participated in the Battle of Port Royal in South Carolina early in the American Civil War. Commissioned as a lieutenant in 1861, Mahan served as an officer on and and as an instructor at the Naval Academy. In 1865, he was promoted to lieutenant commander, and then to commander, and captain. As commander of the he was stationed at Callao, Peru, protecting U.S. interests during the final stages of the War of the Pacific.While in actual command of a ship, his skills were not exemplary; and a number of vessels under his command were involved in collisions with both moving and stationary objects. He preferred old square-rigged vessels rather than smoky, noisy steamships of his own day; and he tried to avoid active sea duty.
Naval War College and writings
In 1885, he was appointed as a 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. During his first year on the faculty, he remained at his home in New York City researching and writing his lectures. Though he was prepared to become a professor in 1886, Luce was given command of the North Atlantic Squadron, and Mahan became President of the Naval War College by default. There, in 1888, he met and befriended future president Theodore Roosevelt, then a visiting lecturer.Mahan's lectures, based on secondary sources and the military theories of Antoine-Henri Jomini, became his sea-power studies: The Influence of Sea Power upon History, 1660–1783 ; The Influence of Sea Power upon the French Revolution and Empire, 1793–1812 ; Sea Power in Relation to the War of 1812, and The Life of Nelson: The Embodiment of the Sea Power of Great Britain. Mahan stressed the importance of the individual in shaping history and extolled 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 his biography as a platform for expressing his views on naval strategy and tactics. Mahan was criticized for so strongly condemning Nelson's love affair with Lady Emma Hamilton, but it remained the standard biography until the appearance of Carola Oman's Nelson, 50 years later.
Mahan struck up a friendship with pioneering British naval historian Sir John Knox Laughton, the pair maintaining the relationship through correspondence and visits when Mahan was in London. Mahan was later described as a "disciple" of Laughton, but the two were at pains to distinguish between each other's line of work. Laughton saw Mahan as a theorist while Mahan called Laughton "the historian". Mahan worked closely with William McCarty Little, another critical figure in the early history of the Naval War College. A principal developer of wargaming in the United States Navy, Mahan credited Little for assisting him with preparing maps and charts for his lectures and first book.
Origin and limitation of strategic views
Mahan's views were shaped by 17th-century conflicts between the Dutch Republic, the Kingdom of England, the Kingdom of France, and Habsburg Spain, and by the naval conflicts between France and Spain during the French Revolutionary and Napoleonic Wars. British naval superiority eventually defeated France, consistently preventing invasion and an effective blockade. Mahan emphasized that naval operations were chiefly to be won by decisive battles and blockades. In the 19th century, the United States sought greater control over its seaborne commerce in order to protect its economic interests which relied heavily on exports bound mainly for Europe.According to Peter Paret's Makers of Modern Strategy from Machiavelli to the Nuclear Age, Mahan's emphasis on sea power as the most important cause of Britain's rise to world power neglected diplomacy and land arms. Furthermore, theories of sea power do not explain the rise of land empires, such as Otto von Bismarck's German Empire or the Russian Empire.
Sea power
Mahan believed that national greatness was inextricably associated with the sea, with its commercial use in peace and its control in war; and he used history as a stock of examples to exemplify his theories, arguing that the education of naval officers should be based on a rigorous study of history. Mahan's framework derived from Jomini, and emphasized strategic locations, as well as quantifiable levels of fighting power in a fleet. Mahan also believed that in peacetime, states should increase production and shipping capacities and acquire overseas possessions, though he stressed that the number of coal fueling stations and strategic bases should be limited to avoid draining too many resources from the mother country.The primary mission of a navy was to secure the command of the sea, which would permit the maintenance of sea communications for one's own ships while denying their use to the enemy and, if necessary, closely supervise neutral trade. Control of the sea could be achieved not by destruction of commerce but only by destroying or neutralizing the enemy fleet. Such a strategy called for the concentration of naval forces composed of capital ships, not too 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 a command of the sea, even if local and temporary, naval operations in support of land forces could be of decisive importance. He also believed that naval supremacy could be exercised by a transnational consortium acting in defense of a multinational system of free trade. His theories, expounded before the submarine became a serious factor in warfare, delayed the introduction of convoys as a defense against the Imperial German Navy's U-boat campaign during World War I. By the 1930s, the U.S. Navy had built long-range submarines to raid Japanese shipping; but in World War II, the Imperial Japanese Armed Forces, still tied to Mahan, designed its submarines as ancillaries to the fleet and failed to attack American supply lines in the Pacific. Mahan's analysis of the Spanish–American War suggested to him that the great distances in the Pacific required the American battle fleet to be designed with long-range striking power.
Mahan believed first, that good political and naval leadership was no less important than geography when it came to the development of sea power. Second, Mahan's unit of political analysis insofar as sea power was concerned was a transnational consortium, rather than a single nation state. Third, his economic ideal was free trade rather than autarky. Fourth, his recognition of the influence of geography on strategy was tempered by a strong appreciation of the power of contingency to affect outcomes.
In 1890, Mahan prepared a secret contingency plan for war between the British Empire and the United States. Mahan believed that if the Royal Navy blockaded the East Coast of the United States, the US Navy should be concentrated in one of its ports, preferably New York Harbor with its two widely separated exits, and employ torpedo boats to defend the other harbors. This concentration of the U.S. fleet would force the British to tie down such a large proportion of their navy to watch the New York exits that other American ports would be relatively safe. Detached American cruisers should wage "constant offensive action" against the enemy's exposed positions; and if the British were to weaken their blockade force off New York to attack another American port, the concentrated U.S. fleet could capture British coaling ports in Nova Scotia, thereby seriously weakening British ability to engage in naval operations off the American coast. This contingency plan was a clear example of Mahan's application of his principles of naval war, with a clear reliance on Jomini's principle of controlling strategic points.
