"P.S. I came here by force, the Spanish consul having seized me under a supposed order of the Second Municipality and having had me carried by main force on board a ship at nine in the evening. "P.S.--I did not speak frankly to you because the Captain of the port was present." The request which the American consul promptly made for an interview with Rey was denied, and at this point the United States government interested itself in the case and made an official demand for the return of Rey. Relations between the United States and Spain were growing very much strained and it looked as if the United States were soon to have an excuse to fight Spain and to annex Cuba, when the Spanish government suddenly suffered a change of heart, and Rey was pardoned and released. Meanwhile the plans for the invasion of Cuba were being carried out so openly that the Spanish minister protested, and Zachary Taylor, then President of the United States, being unwilling openly to affront Spain, through his Secretary of State, John M. Clayton, issued on August 11, 1849, a proclamation which ran as follows: "There is reason to believe that an armed expedition is about to be fitted out in the United States with an intention to invade the Island of Cuba, or some of the provinces of Mexico. The best information which the executive has been able to obtain, points to the Island of Cuba as the object of this expedition. It is the duty of this government to observe the faith of treaties, and to prevent any aggression by our citizens upon the territories of friendly nations. I have, therefore, thought it necessary and proper to issue this proclamation, to warn all citizens of the United States who shall connect themselves with an enterprise so grossly in violation of our laws and treaty obligations, that they will thereby subject themselves to the heavy penalties denounced against them by our Acts of Congress, and will forfeit their claim to the protection of their country. No such persons must expect the interference of this government in any form on their behalf, no matter to what extremities they may be reduced in consequence of their conduct. An enterprise to invade the territories of a friendly nation, set on foot and prosecuted within the limits of the United States, is in the highest degree criminal, as tending to endanger the peace and compromise the honor of this nation, and therefore I exhort all good citizens, as they regard our national reputation, as they respect their own laws and the laws of nations, as they value the blessings of peace and the welfare of their country, to discountenance and prevent, by all lawful means, any such enterprise; and I call upon every officer of this government, civil or military, to use all efforts in his power to arrest for trial and punishment every such offender against the laws providing for the performance of our sacred obligations to friendly powers."
