On the first of May, Congress passed an act which revoked the restrictive system, yet excluded British and armed vessels from the waters of the United States.[4] It provided, however, that it should be renewed in March against the nation, which did not before that time so revoke or modify its edicts, as to protect the neutral commerce of the United States. This was regarded as the ultimatum, and beyond it, war against which ever government refused our just demands, was the only resort. Messrs. Pinckney and Armstrong, our ministers at the courts of England and France, were urged to press the repeal of those obnoxious orders in council and decrees, in order that such a catastrophe might be prevented. France receded, and Mr. Armstrong was notified that the decrees were to cease to have effect after the first of November, provided England withdrew her orders in council; or, if she refused, that the United States should force her to acknowledge the rights that France had, in a spirit of kindness, conceded. This glad intelligence was made known by the President in a proclamation, in which he also declared, that unless the British government repealed her orders in council, within three months from that date, the non-intercourse law should be revived against it. [Footnote 4: Act of Congress, passed 1st of May, 1810.] In the mean time Mr. Pinckney urged, with all the arguments in his power, the English Cabinet to recede from its unjustifiable position. The latter endeavored, by prevarication and duplicity, to avoid coming to a definite understanding, but being closely pushed, it at length gave our minister to understand that the United States must force France to take the first step in revoking those odious acts against which we complained. But as England had been the aggressor, this was plainly unjust and impossible, and all hope of a peaceful settlement was given up, and on the 1st of March, 1811, he took a formal leave of the Prince Regent. At the same time Congress had passed an act, authorizing the President to arrest the non-intercourse Act at any moment that England should revoke her orders in council. [Sidenote: April, 1811.] On the 38th of the next month, Napoleon definitely revoked his Berlin and Milan decrees, so far as they related to us--the repeal to be ante-dated November 1st, 1810. This decree was forwarded by our minister, Mr. Barlow, who had succeeded Armstrong, to the English Government, but it still refused to repeal its orders in council on the ground that the decree did not embrace the continental states, and affected only the United States. It soon became apparent, therefore, to every one, that war was inevitable. The American Government had placed itself, where it could not recede without disgrace, while England was evidently resolved not to change her attitude. [Sidenote: 1811.]
