Reports of this open defiance and insurrection on the Canada frontier reached Washington at the same time with other reports which revealed endless annoyances elsewhere. If the embargo was to coerce England or France, it must stop supplies to the West Indian colonies, and prevent the escape of cotton or corn for the artisans of Europe. The embargo aimed at driving England to desperation, but not at famishing America; yet the President found himself at a loss to do the one without doing the other. Nearly all commerce between the States was by coasting-vessels. If the coasting-trade should be left undisturbed, every schooner that sailed from an American port was sure to allege that by stress of weather or by the accidents of navigation it had been obliged to stop at some port of Nova Scotia or the West Indies, and there to leave its cargo. Only the absolute prohibition of the coasting-trade could prevent these evasions; but to prohibit the coasting-trade was to sever the Union. The political tie might remain, but no other connection could survive. Without the coasting-trade New England would be deprived of bread, and her industries would perish; Charleston and New Orleans would stagnate in unapproachable solitude. Jefferson proclaimed the existence of an insurrection on the Canadian frontier shortly before the adjournment of Congress. Immediately after the adjournment he took in hand the more serious difficulties of the coasting-trade. The experiment of peaceable coercion was at last to have full trial, and Jefferson turned to the task with energy that seemed to his friends excessive, but expressed the vital interest he felt in the success of a theory on which his credit as a statesman depended. The crisis was peculiarly his own; and he assumed the responsibility for every detail of its management. May 6 the President wrote to Gallatin a letter containing general directions to detain in port every coasting-vessel which could be regarded as suspicious. His orders were sweeping. The power of the embargo as a coercive weapon was to be learned. “In the outset of the business of detentions,” said the President,[198] “I think it impossible to form precise rules. After a number of cases shall have arisen, they may probably be thrown into groups and subjected to rules. The great leading object of the Legislature was, and ours in execution of it ought to be, to give complete effect to the embargo laws. They have bidden agriculture, commerce, navigation to bow before that object,--to be nothing when in competition with that. Finding all their endeavors at general rules to be evaded, they finally gave us the power of detention as the panacea; and I am clear we ought to use it freely, that we may by a fair experiment know the power of this great weapon, the embargo.”
