The commissioned officers of the Legion were constituted its court-martial, which was its law-making department; but no law inconsistent with either the Constitution of the United States or the State of Illinois was to be enacted by this court. The privilege of organizing the citizens of Nauvoo, and as many of the citizens of Hancock County as might desire to unite with them, into an independent military body, was highly gratifying to the people of Nauvoo, but more especially so to Joseph Smith, who, in speaking of it, in a proclamation to the Saints scattered abroad, said: The Nauvoo Legion embraces all our military power, and will enable us to perform our military duty by ourselves, and thus afford us the power and privileges of avoiding one of the most fruitful sources of strife, oppression and collision with the world. It will enable us to show our attachment to the State and Nation, as a people, whenever the public service requires our aid, thus proving ourselves obedient to the paramount laws of the land, and ready at all times to sustain and execute them. The city ordinance provided that the Legion should be divided into two cohorts, the horse troops to constitute the first cohort, and the infantry the second. The commander-in-chief of the Legion was to be known as the lieutenant-general, who was also made the reviewing officer and president of the court-martial and Legion. His staff was to consist of two principal aides-de-camp with the rank of colonel of cavalry; and a guard of twelve aides-de-camp with the rank of captain of infantry; and a drill officer, with the rank of colonel of dragoons, to be the chief officer of the guard. The second officer was a major-general, to act as the secretary of the court-martial and Legion. His staff consisted of an adjutant; surgeon-in-chief, a cornet, quartermaster, paymaster, commissary, and chaplain; all to hold the rank of colonel of cavalry; besides these, there were to be in his staff, a surgeon for each cohort, quartermaster sergeant, sergeant-major, and a chief musician--with the rank of captain of light infantry; and two musicians with the rank of captain of infantry. Besides these officers there were created by the ordinance an adjutant and inspector-general; and a brigadier-general to command each cohort. The staff of each brigadier-general consisted of an aide-de-camp with the rank of lieutenant-colonel of infantry, and when not otherwise in service, these brigadiers had access to the staff of the major-general.
