1st.  The marshal (or general) commanding-in-chief; and one colonel or lieutenant-colonel, one major, three captains and three subalterns, as aides-de-camp.

2d.  A lieutenant-general as chief-of-staff, with the title of major-general, assisted by one colonel or lieutenant-colonel, three majors, five captains, and one subaltern, as aides-de-camp.

3d.  Three lieutenant-generals, commanding the corps d’armee and reserve.  Each of these will be assisted by aides in the same way as the major-general, and each will also have his regularly-organized staff of corps d’armee, with a general of division or general of brigade as chief.

4th.  Six or nine generals commanding divisions, each having his own distinct and separately organized staff.  In the French army, the staff of an officer commanding a division is composed of one colonel, two majors, three captains, and six subalterns.

5th.  Twelve or more generals of brigade, each having one captain, and one subaltern for aides.

6th.  There is also attached to the staff of the general-in-chief of the army, the commandants of artillery and engineers, with several subordinates, inspector-generals, and the ranking officers of each of the administrative departments, with their assistants.

The generals select their aides and assistants from the staff corps, or from either of the four arms of service.

The troops of these arms may be distributed as follows: 

52 battalions of infantry, 35,000 men.
42 squadrons of horse, . . 6,500 "
13 batteries of artillery, (4 mounted and 9 foot,) . 2,500 "
5 companies of sappers, 2 of pontoniers,[29] and 1 of artificers,
. . . . . 1,500 "
------
45,500 "

[Footnote 29:  One bridge-equipage is required for each corps d’armee.]

If we add to these the staff, and the several officers and employes of the administrative departments, we have an army of nearly fifty thousand men.

This, it will be remembered, is the organization of an army in the field; in the entire military organization of a state, the number of staff officers will be still higher.

In 1788, France, with a military organization for about three hundred and twenty thousand men, had eighteen marshals, two hundred and twenty-five lieutenant-generals, five hundred and thirty-eight marechaux-de-camp, and four hundred and eighty-three brigadiers.  A similar organization of the general staff was maintained by Napoleon.  At present the general staff of the French army consists of nine marshals, (twelve in time of war;) eighty lieutenant-generals in active service, fifty-two in reserve, and sixty two en retraite—­one hundred and ninety-four in all; one hundred and sixty marechaux-de-camp in active service, eighty-six in reserve, and one hundred and ninety en retraite—­four hundred and thirty-six in all.  The officers of the staff-corps are:  thirty colonels, thirty lieutenant-colonels, one hundred majors, three hundred captains, and one hundred lieutenants.  Those of other European armies are organized on the same basis.
