The two principal immediate causes of the War of 1812 were the impressment of seamen from American merchant ships, upon the high seas, to serve in the British Navy, and the interference with the carrying trade of the United States by the naval power of Great Britain. For a long time this interference was confined by the British Ministry to methods which they thought themselves able to defend—as they did the practice of impressment—upon the ground of rights, prescriptive and established, natural or belligerent; although the American Government contended that in several specific measures no such right existed,—that the action was illegal as well as oppressive. As the war with Napoleon increased in intensity, however, the exigencies of the struggle induced the British cabinet to formulate and enforce against neutrals a restriction of trade which it confessed to be without sanction in law, and justified only upon the plea of necessary retaliation, imposed by the unwarrantable course of the French Emperor. These later proceedings, known historically as the Orders in Council,1 by their enormity dwarfed all previous causes of complaint, and with the question of impressment constituted the vital and irreconcilable body of dissent which dragged the two states into armed collision. Undoubtedly, other matters of difficulty arose from time to time, and were productive of dispute; but either they were of comparatively trivial importance, easily settled by ordinary diplomatic methods, or there was not at bottom any vital difference as to principle, but only as to the method of adjustment. For instance, in the flagrant and unpardonable outrage of taking men by force from the United States frigate "Chesapeake," the British Government, although permitted by the American to spin out discussion over a period of four years, did not pretend to sustain the act itself; the act, that is, of searching a neutral ship of war. Whatever the motive of the Ministry in postponing redress, their pretexts turned upon points of detail, accessory to the main transaction, or upon the subsequent course of the United States Government, which showed conscious weakness by taking hasty, pettish half-measures; instead of abstaining from immediate action, and instructing its minister to present an ultimatum, if satisfaction were shirked.
In the two causes of the war which have been specified, the difference was fundamental. Whichever was right, the question at stake was in each case one of principle, and of necessity. Great Britain never claimed to impress American seamen; but she did assert that her native-born subjects could never change their allegiance, that she had an inalienable right to their service, and to seize them wherever found, except within foreign territory. From an admitted premise, that the open sea is common to all nations, she deduced a common jurisdiction, in virtue of which she arrested her vagrant seamen. This argument of right was reinforced by a paramount necessity. In a life and death struggle with an implacable enemy, Great Britain with difficulty could keep her fleet manned at all; even with indifferent material. The deterioration in quality of her ships' companies was notorious; and it was notorious also that numerous British seamen sought employment in American merchant ships, hoping there to find refuge from the protracted confinement of a now dreary maritime war. Resort to impressment was not merely the act of a high-handed Government, but the demand of both parties in the state, coerced by the sentiment of the people, whose will is ultimately irresistible. No ministry could hope to retain power if it surrendered the claim to take seamen found under a neutral flag. This fact was thoroughly established in a long discussion with United States plenipotentiaries, five years before the war broke out.
On the other hand, the United States maintained that on the sea common the only jurisdiction over a ship was that of its own nation. She could not admit that American vessels there should be searched, for other purposes than those conceded to the belligerent by international law; that is, in order to determine the nature of the voyage, to ascertain whether, by destination, by cargo, or by persons carried, the obligations of neutrality were being infringed. If there was reasonable cause for suspicion, the vessel, by accepted law and precedent, might be sent to a port of the belligerent, where the question was adjudicated by legal process; but the actual captor could not decide it on the spot. On the contrary, he was bound, to the utmost possible, to preserve from molestation everything on board the seized vessel; in order that, if cleared, the owner might undergo no damage beyond the detention. So deliberate a course was not suited to the summary methods of impressment, nor to the urgent needs of the British Navy. The boarding officer, who had no authority to take away a bale of goods, decided then and there whether a man was subject to impressment, and carried him off at once, if he so willed.
It is to the credit of the American Government under Jefferson, that, though weak in its methods of seeking redress, it went straight back of the individual sufferer, and rested its case unswervingly on the broad principle.2 That impressment, thus practised, swept in American seamen, was an incident only, although it grievously aggravated the injury. Whatever the native allegiance of individuals on board any vessel on the open ocean, their rights were not to be regulated by the municipal law of the belligerent, but by that of the nation to which the ship belonged, of whose territory she was constructively a part, and whose flag therefore was dishonored, if acquiescence were yielded to an infringement of personal liberty, except as conceded by obligations of treaty, or by the general law of nations. Within British waters, the United States suffered no wrong by the impressment of British subjects—the enforcement of local municipal law—on board American vessels; and although it was suggested that such visits should not be made, and that an arriving crew should be considered to have the nationality of their ship, this concession, if granted, would have been a friendly limitation by Great Britain of her own municipal jurisdiction. It therefore could not be urged upon the British Government by a nation which took its stand resolutely upon the supremacy of its own municipal rights, on board its merchant shipping on the high seas.
It is to be noted, furthermore, that the voice of the people in the United States, the pressure of influence upon the Government, was not as unanimous as that exerted upon the British Ministry. The feeling of the country was divided; and, while none denied the grievous wrong done when an American was impressed, a class, strong at least in intellectual power, limited its demands to precautions against such mistakes and to redress when they occurred. The British claim to search, with the object of impressing British subjects, was considered by these men to be valid. Thus Gouverneur Morris, who on a semi-official visit to London in 1790 had had occasion to remonstrate upon the impressment of Americans in British ports, and who, as a pamphleteer, had taken strong ground against the measures of the British Government injurious to American commerce, wrote as follows in 1808 about the practice of seizing British subjects in American ships: "That we, the people of America, should engage in ruinous warfare to support a rash opinion, that foreign sailors in our merchant ships are to be protected against the power of their sovereign, is downright madness." "Why not," he wrote again in 1813, while the war was raging, "waiving flippant debate, lay down the broad principle of national right, on which Great Britain takes her native seamen from our merchant ships? Let those who deny the right pay, suffer, and fight, to compel an abandonment of the claim. Men of sound mind will see, and men of sound principle will acknowledge, its existence." In his opinion, there was but one consistent course to be pursued by those who favored the war with Great Britain, which was to insist that she should, without compensation, surrender her claim. "If that ground be taken," he wrote, "the war [on our part] will be confessedly, as it is now impliedly, unjust."3 Morris was a man honorably distinguished in our troubled national history—a member of the Congress of the Revolution and of the Constitutional Convention, a trained lawyer, a practised financier, and an experienced diplomatist; one who throughout his public life stood high in the estimation of Washington, with whom he was in constant official and personal correspondence. It is to be added that those to whom he wrote were evidently in sympathy with his opinions.
So again Representative Gaston, of North Carolina, a member of the same political party as Morris, speaking from his seat in the House in February, 1814,4 maintained the British doctrine of inalienable allegiance. "Naturalization granted in another country has no effect whatever to destroy the original primary allegiance." Even Administration
