It requires no skill in the science of war to discern that uniformity in the organization and discipline of the militia would be attended with the most beneficial effects, whenever they were called into service for the public defense. It would enable them to discharge the duties of the camp and of the field with mutual intelligence and concert an advantage of peculiar moment in the operations of an army; and it would fit them much sooner to acquire the degree of proficiency in military functions which would be essential to their usefulness. This desirable uniformity can only be accomplished by confiding the regulation of the militia to the direction of the national authority. It is, therefore, with the most evident propriety, that the plan of the convention proposes to empower the Union “to provide for organizing, arming, and disciplining the militia, and for governing such part of them as may be employed in the service of the United States, RESERVING TO THE STATES RESPECTIVELY THE APPOINTMENT OF THE OFFICERS, AND THE AUTHORITY OF TRAINING THE MILITIA ACCORDING TO THE DISCIPLINE PRESCRIBED BY CONGRESS.” Of the different grounds which have been taken in opposition to the plan of the convention, there is none that was so little to have been expected, or is so untenable in itself, as the one from which this particular provision has been attacked. If a well-regulated militia be the most natural defense of a free country, it ought certainly to be under the regulation and at the disposal of that body which is constituted the guardian of the national security. If standing armies are dangerous to liberty, an efficacious power over the militia, in the body to whose care the protection of the State is committed, ought, as far as possible, to take away the inducement and the pretext to such unfriendly institutions. If the federal government can command the aid of the militia in those emergencies which call for the military arm in support of the civil magistrate, it can the better dispense with the employment of a different kind of force. If it cannot avail itself of the former, it will be obliged to recur to the latter. To render an army unnecessary, will be a more certain method of preventing its existence than a thousand prohibitions upon paper.
