In time of war, as we shall see, the powers of the military commander, in the control of his own men, and of the citizens of the State to which he belongs, are much broader than they are in time of peace, but it is still true that they are subject to the limitations which the civil law imposes. With respect to the persons and property of the enemy, however, he is subject only to the limitations which the laws of war, as determined by international usage, supply, and for violation of these he is responsible only to the military tribunals.
