JEFFERSON. PROCLAMATIONS. BY THOMAS JEFFERSON, PRESIDENT OF THE UNITED STATES OF AMERICA. A PROCLAMATION. During the wars which for some time have unhappily prevailed among the powers of Europe the United States of America, firm in their principles of peace, have endeavored, by justice, by a regular discharge of all their national and social duties, and by every friendly office their situation has admitted, to maintain with all the belligerents their accustomed relations of friendship, hospitality, and commercial intercourse. Taking no part in the questions which animate these powers against each other, nor permitting themselves to entertain a wish but for the restoration of general peace, they have observed with good faith the neutrality they assumed, and they believe that no instance of a departure from its duties can be justly imputed to them by any nation. A free use of their harbors and waters, the means of refitting and of refreshment, of succor to their sick and suffering, have at all times and on equal principles been extended to all, and this, too, amidst a constant recurrence of acts of insubordination to the laws, of violence to the persons, and of trespasses on the property of our citizens committed by officers of one of the belligerent parties received among us.

This enormity was not only without provocation or justifiable cause, but was committed with the avowed purpose of taking by force from a ship of war
