If the friendly Whigs, after imposing on the United States such a treaty, had thought themselves still obliged to lop off another main limb of American commerce, which Pitt had spared, the Tories were not likely to rest until they had put an end to American neutral commerce altogether. This result was foreshadowed by Spencer Perceval and Lord Castlereagh in their speeches on Lord Howick’s order, and was the end to which the legislation and public opinion of England had pointed for years. The time for negotiation had gone by, and nothing remained for the United States but a trial of strength. For this final test Jefferson was ready. Congress had placed in his hands powers which in his opinion were ample to protect American interests abroad and at home. On sufficient provocation he could exclude British ships-of-war from American waters, and if they should refuse to depart he might enforce the Non-importation Act against British commerce. His conduct proved that he felt neither fear nor hesitation. He had never expected a satisfactory treaty from England, and he had good reason to know that Monroe’s treaty, if Monroe should succeed in making one, must be worse than none. Early in February, 1807, arrived the despatch from Monroe and Pinkney announcing that the two envoys had decided to depart from their instructions and to abandon the impressment ultimatum. Madison replied,[297] February 3, that no such treaty would be ratified, and that it would be better to let the negotiation quietly terminate, leaving each party to follow an informal understanding; but that if such a treaty should have been signed, the British commissioners should be candidly apprised of the reasons for not expecting its ratification. That Monroe’s treaty, if he made one, would be rejected and returned without ratification to the British government was certain long before it reached America. On that point, as on the inflexibility of England, no doubt could exist. President Jefferson and Secretary Madison were as determined, in case of necessity, to attack British manufactures as Spencer Perceval and George Rose were bent upon cutting off American trade; but although the Americans fully meant to use commercial weapons against British aggression, they earnestly wished for a good working arrangement under which, without a treaty, peace and commerce could be secure. So far from challenging a rupture, they were anxious only to encourage cordial relations. Throughout the winter of 1806–1807 Jefferson made of his attachment to England a foundation for all his policy at home and abroad. Congress, under the security of Fox’s friendship, left foreign affairs alone, and quarrelled only about domestic matters; while General Turreau’s temper was made more irritable by the attentions lavished upon David Montague Erskine, the new British minister, who, Nov. 4, 1806, put an end to the adventures of Merry at Washington, and began the easy task of winning popularity.
