By 1805, the British shipowners felt that flesh and blood could not endure the situation. Here were France and her allies easily escaping the hardships of British naval pressure by employing neutrals to carry on their trade. Worse still, the Americans, by the device of entering and clearing {192} French sugar at an American port, were now able calmly to take it to England and undersell the West Indian planters in their own home markets. Pamphleteers began to criticize the government for permitting such unfair competition, Lord Sheffield, as in 1783, leading the way. In October, 1805, James Stephen, a far abler writer, summed up the anger of the British ship-owners and naval officers in a pamphlet entitled, "War in disguise, or the Frauds of the Neutral Trade." He asserted that the whole American neutral commerce was nothing more or less than an evasion of the Rule of 1756 for the joint benefit of France and the United States, and he called upon the government to put a stop to this practical alliance of America with Napoleon. This utterance seems to have made a profound impression; for a time Stephen's views became the fixed beliefs of influential public men as well as of the naval and shipowning interests.

The first steps indicating British restlessness were taken by the Pitt Ministry, which began, in 1804, a policy of rigid naval search for contraband cargoes, largely carried on off American ports. Whatever friendly views Pitt may once have entertained toward the Americans, his Ministry now had for its sole object the contest with {193} France and the protection of British interests. In July, 1805, a severe blow was suddenly struck by Sir William Scott, who as chief Admiralty judge rendered a decision to the effect that French sugar, entered at an American custom-house and re-exported with a rebate of the duty, was good prize under the Rule of 1756. This placed all American re-exportation of French West Indian produce at the mercy of British cruisers; and the summer of 1805 saw a sudden descent of naval officers upon their prey, causing an outcry of anger from every seaport between Maine and Maryland. The day of reckoning had come, and Jefferson and Madison, his Secretary of State, were compelled to meet the crisis. Fortunately, as it appeared, for the United States, the Pitt Ministry ended with the death of its leader on January 23, 1806, and was succeeded by a coalition in which Lord Grenville, author of the Jay treaty, was prime Minister, and Fox, an avowed friend of America, was Foreign Secretary. While it was not reasonably to be expected that any British Ministry would throw over the traditional naval policy of impressments or venture to run directly counter to shipping interests, it was open to anticipation that some such compromise as the Jay treaty might be agreed upon, which would relieve the United {194} States from arbitrary exactions during the European war. The Grenville Ministry showed its good intentions by abandoning the policy of captures authorized by Scott, and substituting, on May 16, 1806, a blockade of the French coast from Ostend to the Seine. This answered the purpose of hindering trade with France without raising troublesome questions, and actually allowed American vessels to take sugar to Northern Europe.

Between 1804 and 1806, Jefferson had brought the United States to the verge of war with Spain through insisting that Napoleon's cession of Louisiana had included West Florida. At the moment when British seizures began, he was attempting at once to frighten Spain by warlike words and, by a payment of two million dollars, to induce France to compel Spain to acknowledge the American title to the disputed territory. For a number of years, therefore, and until the scheme fell through, Jefferson cultivated especially friendly relations with the government of Napoleon, not from any of the former Republican enthusiasm, but solely on diplomatic grounds. Hence, although nominally neutral in the great war, he bore the appearance of a French partisan.

Jefferson felt that he had in his possession a thoroughly adequate means to secure {195} favourable treatment from England, by simply threatening commercial retaliation. The American trade, he believed, was so necessary to the prosperity of England that for the sake of retaining it that country would make any reasonable concession. That there was a basis of truth in this belief it would be impossible to deny; for England consumed American cotton and exported largely to American markets. With this trade cut off, manufacturers and exporters would suffer, as they had suffered in the revolutionary period. But Jefferson ignored what every American merchant knew, that military and naval considerations weighed fully as heavily with England as mercantile needs, and that a country which had neither a ship-of-the-line, nor a single army corps in existence, commanded, in an age of world warfare, very slight respect. Jefferson's prejudice against professional armed forces and his ideal of war as a purely voluntary matter, carried on as in colonial times, was sufficiently proclaimed by him to be well understood across the Atlantic. Openly disbelieving in war, avowedly determined not to fight, he approached a nation struggling for life with the greatest military power on earth, and called upon it to come to terms for business reasons.

His first effort was made by causing {196} Congress to pass a Non-importation Act, excluding certain British goods, which was not to go into effect until the end of 1806. With this as his sole weapon, he sent Monroe to make a new treaty, demanding free commerce and the cessation of the impressment of seamen from American vessels in return for the continued non-enforcement of the Non-importation Act. Such a task was more difficult than that laid upon Jay twelve years before; and Monroe, in spite of the fact that he was dealing with the same Minister, failed to accomplish even so much as his predecessor. From August to December he negotiated, first with Lord Holland, then, after Fox's death, with Lord Howick; but the treaty which he signed on December 1, 1806, contained not one of the points named in his instructions. Monroe found the British willing to make only an agreement like the Jay treaty which, while containing special provisions to render the situation tolerable, should refuse to yield any British contentions. That was the Whig policy as much in 1806 as it had been in 1766. The concessions were slight; and the chief one, regarding the re-exportation of French West Indian produce, permitted it only on condition that the goods were bona fide of American ownership, and had paid in the United States a duty of at least two per cent. Jefferson {197} did not even submit the treaty to the Senate.

After this failure, the situation grew graver. Napoleon, in December, 1806, issued from Berlin a decree declaring that, in retaliation for the aggressions of England upon neutral commerce, the British Isles were in blockade and all trade with them was forbidden. British goods were to be absolutely excluded from the continent. The reply of the Grenville Ministry to this was an Order in Council, January, 1807, prohibiting neutral vessels from trading between the ports of France or her allies; but this was denounced as utterly weak by Perceval and Canning in opposition. In April, 1807, the Grenville Ministry, turned out of office by the half insane George III, was replaced by a thoroughly Tory cabinet, under the Duke of Portland, whose chief members in the Commons were George Canning and Spencer Perceval, Foreign Secretary and Chancellor of the Exchequer respectively. The United States was now to undergo treatment of a new kind at the hands of Tories who despised its institutions, felt only contempt for the courage of its government, and were guided as regards American commerce by the doctrines of Lord Sheffield and James Stephen.

An Order in Council of November 11, {198} 1807, drafted by Perceval and endorsed by all the rest of the Cabinet, declared that no commerce with France or her allies was henceforward to be permitted unless it had passed through English ports. To this Napoleon retorted by the Milan Decree of December, 1807, proclaiming that all vessels which had been searched by British, or which came by way of England, were good prize. Henceforth, then, neutral commerce was positively prohibited. The merchantmen of the United States could continue to trade at all only by definitely siding with one power or the other. The object of the British order was declared to be retaliation on Napoleon. Its actual effect was to place American trade once more under the rule of the Navigation Acts. As in the days before 1776, American vessels must make England their "staple" or "entrepôt," and could go only where permitted to by British orders under penalty of forfeiture. This measure was sharply attacked in Parliament by the Whigs, especially by Grenville and Howick, of the late Ministry, but was triumphantly sustained by the Tories.

At this time the chronic grievance of the impressment of seamen from American vessels grew suddenly acute. In the years of the great war, the American merchant marine, {199} with its safe voyages and good pay, offered a highly attractive prospect for English sailors, who dreaded the danger, the monotony, and the severe discipline of British men-of-war. They swarmed by thousands into American service, securing as rapidly as possible, not infrequently by fraudulent means, the naturalization papers by which they hoped to escape the press-gang. Ever since 1793 British naval officers, recognizing no right of expatriation, had systematically impressed British seamen found on American ships and, owing to the difficulty in distinguishing the two peoples, numerous natives of New England and the middle States found themselves imprisoned on the "floating hell" of a British ship-of-the-line in an epoch when brutality characterized naval discipline. In August, 1807, the United States was stirred to fury over the forcible seizure by the British Leopard of three Englishmen from the U.S.S. Chesapeake, which, unprepared for defence, had to suffer unresisting. So hot was the general anger that Jefferson could easily have led Congress into hostile measures, if not an actual declaration of war, over the multiplied seizures and this last insult.

But Jefferson clung to peace, and satisfied himself by ordering British men-of-war out of American ports and sending a {200} demand for reparation, with which he linked a renunciation of the right of impressment. When Congress met in December, he induced it to pass a general embargo, positively prohibiting the departure of American vessels to foreign ports. Since at the same time the Non-importation Act came into effect, all imports and exports were practically suspended. His idea was that the total cessation of American commerce would inflict such discomfort upon British and French consumers that each country would be forced to abandon its oppressive measures.

Rarely has a country, at the instance of one man, inflicted a severer strain upon its citizens. The ravages of French and English together, since the outbreak of war in 1793, did not do so much damage as the embargo did in one year, for it threatened ruin to every shipowner, importer, and exporter in the United States. Undoubtedly Jefferson and his party had in mind the success of the non-importation agreements against the Stamp Act and the Townshend duties, but what was then the voluntary action of a great majority was now a burden imposed by one part of the country upon another. The people of New York and New England simply would not obey the Act. To enforce it against Canada became an impossibility, and to prevent vessels from escaping a {201} matter of great difficulty. Jefferson persisted doggedly, and induced Congress to pass laws giving revenue collectors extraordinary powers of search and seizure, but without results.
