"The Constitution of the United States declares that Congress shall have authority 'to declare war and make rules concerning captures on land and water,' 'to raise and support armies,' 'to provide and maintain a navy,' 'to make rules for the government and regulation of the land and naval forces,' 'to provide for calling forth the militia to execute the laws of the Union, suppress insurrection, and repel invasion,' and 'to make all laws which shall be necessary and proper for carrying into execution the foregoing powers.' It also declares that 'the citizens of each State shall be entitled to all the privileges and immunities of citizens in the several States,' and that 'the United States shall guarantee to every State in the Union a republican form of government.' Under the exercise of these powers, the Government has gone through a four years' conflict. It has succeeded in putting down armed resistance to its authority. But did the military power which was exercised to put down this armed resistance cease the moment the rebel armies were dispersed? Has the Government no authority to bring to punishment the authors of this rebellion after the conflict of arms has ceased? no authority to hold as prisoners, if necessary, all who have been captured with arms in their hands? Can it be that, the moment the rebel armies are dispersed, the military authority ceases, and they are to be turned loose to arm and organize again for another conflict against the Union? Why, sir, it would not be more preposterous on the part of the traveler, after having, at the peril of his life, succeeded in disarming a highwayman by whom he was assailed, to immediately turn round and restore to the robber his weapons with which to make a new assault.
