Background: Winfield Scott (June 13, 1786 - May 29, 1866) was a United States Army general and the unsuccessful presidential candidate of the Whig Party in 1852. Known as "Old Fuss and Feathers" and the "Grand Old Man of the Army", he served on active duty as a general longer than any other person in American history, is rated as one of the Army's most senior commissioned officers, and is ranked by many historians as the best American commander of his time. Over the course of his 53-year career, he commanded forces in the War of 1812, the Black Hawk War, the Mexican-American War, and the Second Seminole War. He was the army's senior officer at the start of the American Civil War, and conceived the Union strategy known as the Anaconda Plan, which was used to defeat the Confederacy.
Context: From the War of 1812 until he became commanding general of the U.S. Army in 1841, Scott maintained a rivalry with Brevet Major General Edmund P. Gaines. The central issue was the question of which had seniority; should brevet ranks count, which would favor Scott, or were regular Army ranks what mattered, which would favor Gaines? Scott claimed he outranked Gaines because Scott's brevet rank of major general, dated July 25, 1814, made him senior to Gaines, whose brevet was dated August 15, 1814. Gaines argued that he should be senior; his and Scott's promotions to brigadier general, colonel, and lieutenant colonel were all issued on the same dates, but Gaines had been promoted to major while Scott was still a captain. The dispute was important to both because they realized that assignment as the Army's commanding general might be at stake.  Scott served as president of the Army's Board of Tactics in 1815, and supervised the modernization of the Army's drill regulations. He also headed a postwar officer retention board in 1815, with post-war reductions in personnel strength the overriding concern. As a result of the board's recommendations, Jacob Brown was appointed as the Army's commander with the rank of major general; Scott and Gaines were retained as brigadier generals, and Brigadier General Alexander Macomb agreed to accept reduction in rank to colonel in order to serve as the Army's chief of engineers. Scott visited Europe to study French military methods in 1815 and 1816, and translated several of the manuals from Napoleon's Army into English. Scott held command of the Division of the North beginning in 1816. He served again as president of the Board of Tactics in 1821, 1824 and 1826, and again oversaw updating of the Army's field regulations. He began command of the Eastern Department in 1825.  Scott and Gaines were passed over for the commanding general's post in 1828, following the death of Jacob Brown. Aware of the Scott/Gaines rivalry, President John Quincy Adams nominated Macomb. Scott attempted to resign, but it was not accepted. Scott again visited Europe and then resumed command of the Eastern Department in 1829. In 1830, Scott published Abstract of Infantry Tactics, Including Exercises and Manueuvres of Light-Infantry and Riflemen, for the Use of the Militia of the United States.
