Jackson’s highhanded actions in the First Seminole War—his invasion of Spanish territory, capture of Spanish forts, and execution of British subjects—might have had serious diplomatic repercussions if Spain or Great Britain had chosen to make an issue of them; but neither nation did. Negotiations with Spain for the purchase of Florida were already under way, and shortly after the return of the forts to Spain, the Adams-Onís Treaty ceded Florida to the United States in February 1819.
For the Army the most significant aspect of the war had been the near total breakdown in the supply system. From the time Jackson rode out of Nashville in late January 1818 until his first encounter with the Indians early in April, he had had to devote all his energies to feeding his troops. The principal reason for this was the failure of civilian contractors. The folly of depending on civilians for so essential an item as rations had been amply demonstrated in the War of 1812, and Jackson’s experience in the First Seminole War only underscored it. At Calhoun’s suggestion the Congress in April 1818 required contractors to deliver rations in bulk at depots and provided a better system of Army-controlled transportation and supply methods. For the first time since the Revolutionary War, the Army had a Subsistence Department, headed by the Commissary General of Subsistence.
John C. Calhoun and the War Department
Calhoun was convinced that the American frontier ought to be protected by regulars rather than by the militia. Calling the militia into active service, he wrote Brig. Gen. Edmund P. Gaines, was “harassing to them and exhausting to the treasury. Protection is the first object, and the second is protection by the regular force.” But providing a regular force capable of protecting the frontiers north, south, and west, as well as the seacoast, was another matter. In 1820 the Congress called upon the Secretary of War to report on a plan for the reduction of the Army to 6,000 men. Calhoun suggested that the reduction, if it had to come, could be effected by cutting the enlisted personnel of each company to half strength. In time of war the Army could be quickly expanded to a force of 19,000 officers and men. This was the start of the “expansible army” concept.
On March 2, 1821, Congress passed the Reduction Act that cut the enlisted strength of the Army by half (from 11,709 to 5,586) but cut the size of the officer corps by only a fifth (from 680 to 540). Thus, even though the Congress had cut the end strength of the Army overall, its limited reduction of the officer corps confirmed that the idea of an expansible army was beginning to achieve a measure of acceptance. Calhoun, although concerned with the drastic nature of the cuts, pronounced himself reasonably satisfied. The retention of a proportionally larger officer cadre would allow the Army to expand more rapidly upon the approach of war. This was a key milestone on the road to recognizing that the Regular Army and its officer corps was the first line of our nation’s defense rather than relying totally upon the militia or hastily raised, equipped, and trained volunteer units.
The Reduction Act also provided for 7 regiments of infantry and 4 regiments of artillery instead of the existing 8 regiments of infantry, a rifle regiment, a regiment of light artillery, and a corps of artillery comprising 8 battalions. The Ordnance Department was staffed by artillery officers; no ordnance officers were commissioned until 1832. The Northern and Southern Divisions were abolished and replaced by an Eastern and a Western Department, under the respective commands of Generals Scott and Gaines. Only one major general was provided. Because General Jackson had resigned from the Army to become Governor of Florida, the commission remained with General Brown, the hero of Sacket’s Harbor in the War of 1812.
To provide a senior line officer in the chain of command, lack of which had been a serious deficiency during the War of 1812, Calhoun brought Brown to Washington in a position that later became known as Commanding General of the Army. Brown held it until his death in 1828, when he was succeeded by Maj. Gen. Alexander Macomb. When Macomb died in 1841, Maj. Gen. Winfield Scott was appointed. Made a brevet lieutenant general in 1847 (the first three-star general since George Washington), Scott served as Commanding General of the Army until his retirement in 1861.
Secretary Calhoun’s administration accomplished many other important innovations in Army management. Beginning in mid-1822, recruiting depots were opened in major cities, east and west, to enlist men for the Army at large, not for specific units. Though regimental recruiting continued, the General Recruiting Service in its first three years of operation enlisted about 68 percent more men than did the regiments. General Scott prepared a new manual of infantry tactics for regulars and militia and, on the basis of his research in Paris in 1815, prepared the Army regulations of 1821, going minutely into every detail of the soldier’s life, including the ingredients of his soup. The first commissioned Surgeon General, Joseph Lovell, whom Calhoun appointed, further improved the soldier’s diet. Also, by requiring daily weather reports from all medical officers, in an attempt to find some correlation between weather and army diseases, Lovell provided basic data for the first study of weather in the United States and the most complete data of the sort in the world.
Under Calhoun, the work of seacoast fortification went steadily forward. By 1826 eighteen harbors and ports from the Penobscot River to the mouth of the Mississippi had been fortified with a total of thirtyone works, generally consisting of sloping earthworks covered with grass and backed by stone or brick walls. By 1843 the harbor defense program had been extended to thirty-five or forty coastal areas with sixty-nine fortifications either in place or under construction. By then the War Department was placing greater emphasis on heavy artillery (24- and 32-lb. guns and 8-inch howitzers) to keep pace with increasingly heavy naval armaments.
Calhoun early turned his attention to the Military Academy, where Crawford’s attempts at rehabilitation had been impeded by controversy stirred up by the arbitrary actions of Superintendent Capt. Alden Partridge. After Partridge was removed and Bvt. Maj. Sylvanus Thayer was appointed Superintendent in July 1817, the academy became a vital force in maintaining a corps of professionally trained officers. The War Department had sent Thayer to Europe in 1815 as one of the first of a succession of Army officers sent abroad in the early nineteenth century to study, among other things, foreign military schools. With Calhoun’s support, Thayer organized the West Point cadets into tactical units, created the Commandant of Cadets, improved the curriculum, and introduced new methods of instruction. Under his administration, West Point became the premier school for engineers in the United States. For his achievements during his sixteen-year superintendence, Thayer became known as the father of the U.S. Military Academy.
Military education was further advanced in 1824, when, as a result of Calhoun’s proposal for a “school of practice” for men in service, the Artillery School at Fortress Monroe was established. It was the first of the Army’s specialist schools; but unlike most modern schools, it instructed not individuals but an entire unit, which was assigned there for a year’s tour of duty. It was closed in 1835, when all the students were sent to Florida to meet the threat of the Second Seminole War, and it was not reopened until 1858. In 1826, the Infantry School of Practice was established at Jefferson Barracks, Missouri. Both schools were major milestones in the development of a standard doctrine and common training regimen for the new professional army.
Sylvanus Thayer (1785–1872)
Sylvanus Thayer, “father of the Military Academy,” became Superintendent of that struggling institution just nine years after graduating from it. Thayer assumed command in 1817 and instituted sweeping reforms that reflected lessons from his recent tour of European military academies. He introduced a strict code of discipline, emphasized honor and integrity, formalized and expanded the curriculum, ranked cadets within each class, improved the faculty, and confirmed West Point as the foremost engineering school in the nation. When Thayer left in 1833, the U.S. Military Academy was fully comparable to its European counterparts.
In 1818 Calhoun formed the first official and complete artillery system for the three categories of artillery (field, siege and garrison, and seacoast), following recommendations by a board of artillery and ordnance officers he had appointed
