On March 22, 1839, Major General Alexander Macomb left Washington to go to Florida in an unsuccessful attempt to end the expensive and futile war which had already lasted four years against the Seminole Indians. On his staff, accompanying him as aid-de-camp, was Lieutenant John T. Sprague of the 8th Infantry, who maintained the official diary of the expedition. This journal which has not been published in its entirety previously, contains the chronicle of the great council which assembled in May of that year to try to establish peace once more. Although General Macomb’s peace mission failed, Lieutenant Sprague’s diary is of great interest because it contains an acount of the conduct of the negotiations which supplements his own history of the Florida War in which the record of this particular episode is short and extremely sketchy.
