In communicating the embargo to Pinkney, for the information of the British Government,[221] Madison was careful to explain, as he had to the British minister at Washington, that it was a measure of precaution only; not to be considered as hostile in character. This was scarcely candid; coercion of Great Britain, to compel the withdrawal of her various maritime measures objectionable to the United States, was at least a silent partner in the scheme, as formulated to the consciousness of Jefferson and his followers.[222] The motive transpired, as such motives necessarily do; but, even had it not, the operation of the Act, under the conditions of the European war, was so plainly partial between the two belligerents, as to amount virtually to co-operation with Napoleon by the preponderance of injury done to Great Britain. It deprived her of cotton for raw material; of tobacco, which, imported in payment for British manufactures, formed a large element in her commerce with the Continent; of wheat and flour, which to some extent contributed to the support of her people, though in a much less degree than many supposed. It closed to her the American market at the moment that Napoleon and Alexander were actively closing the European; and it shut off from the West Indies American supplies known to be of the greatest importance, and fondly, but mistakenly, believed to be indispensable. All this was well enough, if national policy required. Great Britain then was scarcely in a position to object seriously to retaliation by a nation thinking itself injured; but to define such a measure as not hostile was an insult to her common-sense. It was certainly hostile in nature, it was believed to be hostile in motive, and it intensified feelings already none too friendly. In France, although included in the embargo, and although her action was one of the reasons alleged for its institution, Napoleon expressed approval. It was injurious to England, and added little to the pressure upon France exerted by the Orders in Council through the British control of the ocean. Senator Smith of Maryland, a large shipping merchant, bore testimony to this. "It has been truly said by an eminent merchant of Salem, that not more than one vessel in eight that sailed for Europe within a short time before the embargo reached its destination. My own experience has taught me the truth of this; and as further proof I have in my hand a list of fifteen vessels which sailed for Europe between September 1 and December 23, 1807. Three arrived; two were captured by French and Spaniards; one was seized in Hamburg; and nine carried into England. But for the embargo, ships that would have sailed would have fared as ill, or worse. Not one in twenty would have arrived." Granting the truth of this anticipation, Great Britain might have claimed that, so far as evident danger was concerned, her blockades over long coast-lines were effective.
