“Soon after the commencement of my term of office, the country felt the shock of internecine arms. In view of the great crime attempted against the existence of the nation, it became the duty of this, in common with the other departments of the government, to put forth all its energies to prevent the consummation of that crime. By the existing laws, all postmasters and mail-carriers, and all other persons engaged in handling the mails of the United States, or in clerical service, were required to take the usual oath of allegiance to this government, as well as for the faithful performance of their duties. Whenever it was made apparent by their declarations or by their conduct that there was a practical repudiation of the obligation of this oath, whether the party was a postmaster or a postal contractor, I ordered a removal from office in the one case and the deprivation of contract in the other. Not only was it unsafe to intrust the transportation of the mails to a person who refused or failed to recognize the sanctions of an oath, but to continue payment of public money to the enemies of the government and their allies was to give direct aid and comfort to treason in arms. I could not thus permit this branch of government to contribute to its own overthrow. No other course could have reasonably been expected by such contractors. The _bonâ fide_ observance of that oath, and the duty of allegiance itself, entered into and became a condition, a part of the consideration, of the contract itself. This failing, the department was equitably and legally discharged from its literal obligations. Protection on the part of the government and allegiance on the part of the citizen are correlative, and are conditions mutually dependent in every contract; and the highest public interest demanded the rigid enforcement of this rule of action. Occasional local and transient inconvenience resulted of necessity, but far less than would reasonably have been expected. Loyal men everywhere sustained this action, and speedily furnished the requisite means for continuing the service without increased expense. These changes were mainly called for in parts of Virginia and Maryland and in Kentucky and Missouri. “In the same and in neighboring districts the duties of the appointment-office have been very onerous, from the great number of changes required in post-offices, according to changing phases of public sentiment, individual action, and military occupancy. It is believed that these positions, with rare exceptions, are now held by men of unquestioned loyalty. Where such men could not be found, the offices have been discontinued rather than they should be held by repudiators of public faith and used for purposes hostile to the perpetuity of our national institutions.” On the 23d of September, 1864, Montgomery Blair tendered his resignation of the office of postmaster-general, and the resignation was accepted by the President.
