With the conclusion of the War of 1812, Scott served on a board charged with demobilizing the army and determining who would continue to serve in the officer corps. [[Andrew Jackson]] and Brown were selected as the army's two major generals, while [[Alexander Macomb (general)|Alexander Macomb]], [[Edmund P. Gaines]], Scott, and [[Eleazer Wheelock Ripley]] would serve as the army's four brigadier generals.{{sfn|Eisenhower|1999|pp=103–105}} Jackson became commander of the army's Southern Division, Brown became commander of the army's Northern Division, and the brigadier generals were assigned leadership of departments within the divisions.{{sfn|Eisenhower|1999|p=110}} Scott obtained a leave of absence to study warfare in Europe, though to his disappointment, he reached Europe only after [[Napoleon]]'s final defeat at the [[Battle of Waterloo]].{{sfn|Eisenhower|1999|pp=105–107}} Upon his return to the United States in May 1816, he was assigned to command army forces in parts of the [[Northeastern United States]]. He made his headquarters in [[New York City]] and became part of the city's social life.{{sfn|Eisenhower|1999|pp=108–110}} He earned the nickname "Old Fuss and Feathers" for his insistence on proper military bearing, courtesy, appearance, and discipline.{{sfn|Eisenhower|1999|page=184}} In 1835, Scott wrote ''Infantry Tactics, Or, Rules for the Exercise and Maneuvre of the United States Infantry'', a three-volume work that served as the standard drill manual for the United States Army until 1855.{{sfn|"Civil War - Pre-War Tactical Doctrine"}}

Scott developed a rivalry with Jackson after Jackson took offense to a comment Scott had made at a private dinner in New York, though they later reconciled.{{sfn|Eisenhower|1999|pp=112–115, 118}} He also continued a bitter feud with Gaines that centered over which of them had seniority, as both hoped to eventually succeed the ailing Brown.{{sfn|Eisenhower|1999|pp=119–120}}{{efn|The dispute arose over whether regular or brevet promotions took priority.  Gaines argued for regular commissions because Scott and Gaines were both officially promoted to colonel on March 12, 1813, and brigadier general on March 9, 1814. Gaines's name appeared before Scott's on those orders, making him senior to Scott. Scott argued for brevets because he received his brevet promotion to major general on July 25, 1814, three weeks earlier than Gaines's August 15 brevet, making Scott senior to Gaines.{{sfn|Eisenhower|1999|pp=200–200}}}} In 1821, Congress reorganized the army, leaving Brown as the sole major general and Scott and Gaines as the only brigadier generals; Macomb accepted demotion to colonel and appointment as the chief of engineers, while Ripley and Jackson both left the army.{{sfn|Eisenhower|1999|pp=117–118}} After Brown died in 1828, President [[John Quincy Adams]] passed over Scott and Gaines due to their feuding, instead appointing Macomb. Scott was outraged and asked to be relieved of his commission, but ultimately backed down.{{sfn|Eisenhower|1999|pp=121–123}}
