Such, Mr. President, was the situation of the European world, when Congress deemed it necessary to declare an embargo on our own vessels. Denmark and Prussia, and Russia, and Portugal, had become associated or allied with France; and, with the exception of Sweden, the commerce of our citizens was prohibited, by the mutually vindictive and retaliating belligerents, from the White Sea to the Adriatic. American ships and cargoes were declared the prize and plunder of the contending powers. The widely-extended commerce of our people was to be crushed to atoms between the two mighty millstones, or prudently withdrawn from its dangerous exposure, and detained in safety at home. Policy and prudence dictated the latter measure. And as the ocean was become the scene of political storm and tempest, more dreadful than had ever agitated the physical elements, our citizens were admonished to partake of that security for their persons and property, in the peaceful havens of their country, which they sought in vain on the high seas and in European harbors. The regulations, so destructive to our commerce, were not enacted by us. They were imposed upon us by foreign tyrants. Congress had no volition to vote upon the question. In the shipwreck of our trade, all that remained for us to do, was to save as much as we could from perishing, and as far as our efforts would go, to prevent a total loss. I touch, with a delicate hand, the mission of Mr. Rose. The arrival of this Envoy Extraordinary from Britain was nearly of the same date with an order of his Government, blockading Carthagena, Cadiz, and St. Lucar, and the intermediate ports of Spain, and thereby vexing the commerce of American citizens. The unsuccessful termination of his negotiation has been but a few months since followed by a refusal on the part of his Government to rescind its orders, that work so much oppression to our commerce, on condition of having the embargo suspended in respect to theirs. And the French Ministry has treated a similar friendly and specific overture, from our Executive, with total disregard. In addition to all which we learn, from the highest source of intelligence, that the British naval commander at Barbadoes did, about the middle of October, declare the French leeward Caribbean Islands to be in a state of strict blockade, and cautioning neutrals to govern themselves accordingly, under pain of capture and condemnation. THURSDAY, November 24. _The Embargo._ Mr. GILES addressed the Senate:
