Executive to apply the remedy.

At the time of Mr. Lincoln's inauguration, viz., March 4, 1861, the
Regular Army, by law, consisted of two regiments of dragoons, two
regiments of cavalry, one regiment of mounted rifles, four
regiments of artillery, and ten regiments of infantry, admitting of
an aggregate strength of thirteen thousand and twenty-four officers
and men. On the subsequent 4th of May the President, by his own
orders (afterward sanctioned by Congress), added a regiment of
cavalry, a regiment of artillery, and eight regiments of infantry,
which, with the former army, admitted of a strength of thirty-nine
thousand nine hundred and seventy-three; but at no time during the
war did the Regular Army attain a strength of twenty-five thousand
men.

To the new regiments of infantry was given an organization
differing from any that had heretofore prevailed in this country--
of three battalions of eight companies each; but at no time did
more than one of these regiments attain its full standard; nor in
the vast army of volunteers that was raised during the war were any
of the regiments of infantry formed on the three-battalion system,
but these were universally single battalions of ten companies; so
that, on the reorganization of the Regular Army at the close of the
war, Congress adopted the form of twelve companies for the
regiments of cavalry and artillery, and that of ten companies for
the infantry, which is the present standard.

Inasmuch as the Regular Army will naturally form the standard of
organization for any increase or for new regiments of volunteers,
it becomes important to study this subject in the light of past
experience, and to select that form which is best for peace as well
as war.

A cavalry regiment is now composed of twelve companies, usually
divided into six squadrons, of two companies each, or better
subdivided into three battalions of four companies each. This is
an excellent form, easily admitting of subdivision as well as union
into larger masses.

A single battalion of four companies, with a field-officer, will
compose a good body for a garrison, for a separate expedition, or
for a detachment; and, in war, three regiments would compose a good
brigade, three brigades a division, and three divisions a strong
cavalry corps, such as was formed and fought by Generals Sheridan
and Wilson during the war.

In the artillery arm, the officers differ widel
