On May 9, 1793, the French ordered the capture of vessels loaded with provisions, although expressly excepted by the treaty of 1778. On June 8 the British issued a similar order; and in November the rule of 1756 was again put in force by the British government. Captures at once began by both powers; but the British cruisers were more numerous, did more damage, and thus inclined public sentiment in the United States against England. The pacific Jefferson now came forward as the defender of American interests: Sept. 16, 1793, he sent to Congress a report in which he set forth the aggressions upon American commerce, and recommended a policy of retaliation. Meantime a new grievance had arisen, which was destined to be a cause of the War of 1812. In time of war the commanders of British naval vessels were authorized to "impress" British seamen, even out of British merchant vessels. The search of American merchantmen on the same errand at once began, and was felt by the United States government to be humiliating to the national dignity. The whole country was outraged by the frequent seizure of native Americans, on the pretext that they were English born. Public feeling rose until on March 26, 1794, a temporary embargo was laid, forbidding vessels to depart from American ports. On April 17, a motion was introduced to cut off commercial intercourse with Great Britain. On April 19, therefore, the President appointed John Jay, Chief Justice of the United States, as a special envoy to make a last effort to adjust matters in England. Nevertheless, the non-inter course bill passed the House, and was defeated only by Adams's casting vote in the Senate. [Sidenote: Jay's Treaty.] Fortunately it was a time when communication with Europe was slow. Not until June did Jay reach England. A treaty was negotiated on November 19, but was not received by Washington until after the adjournment of Congress in March, 1795. The treaty had indeed removed some old grievances: the posts were to be evacuated; commissions were to settle the northeast boundary, and to adjust the claims for the British debts; but Jay got no indemnity for the negroes carried away by the British in 1783. The commercial clauses were far less favorable: the discriminating taxes against American shipping were at last withdrawn; but Jay was unable to secure any suitable guarantee for neutral trade, and could obtain no promise to refrain from searching American merchantmen, or seizing English-born sailors found thereon. Above all, the West India trade, which the United States so much desired, was granted only with the proviso that it should be carried on in vessels of less than seventy tons burden. In return for these meagre concessions, granted only for twelve years, the United States agreed not to export to any part of the world "molasses, sugar, coffee, cocoa, or cotton."
