 Scott developed a rivalry with Jackson after the latter took offense to a comment Scott had made at a private dinner in New York, though they later reconciled.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.In 1821, Congress reorganized the army, leaving Brown as the sole major general and Scott and Gaines as the lone brigadier generals; Macomb accepted demotion to colonel and appointment as the chief of engineers, while Ripley and Jackson both left the army.
