On June 22, 1812, President Madison writes to Thomas Jefferson enclosing "paper containing the Declaration of War, which is probably the Proclamation of June 19, 1812. Madison goes on to writes "It is understood that the Federalists in Congress are to put all the strength of their talents into a protest against the war, and that the party at large are to be brought out in all their force." Madison has also just learned about the assassination of the British Prime Minister Perceval which occurred on May 11, 1812. He is unaware that Liverpool has already formed a new government. Madison's letter is reproduced below.
TO THOMAS JEFFERSON June 22, 1812.
Dear Sir,—The inclosed letter was sent to me, with a request that I would forward it. The reason assigned was, that the one of which it is a duplicate was presumed to have miscarried, no answer to it having been received. An answer will, of course, be expected. I inclose a paper containing the Declaration of war, &c, merely to supply a possible miscarriage of others usually received by you. It is understood that the Federalists in Congress are to put all the strength of their talents into a protest against the war, and that the party at large are to be brought out in all their force. It is impossible to say what effect will follow the assassination of Perceval. In England, it is doubted whether there will be a successor of the same kidney; whether Wellesley will be the man, with some modifications not affecting the character of the Cabinet; or whether he will be allowed to make one for himself, in which case it is supposed he will bring in the Tax party. All this will depend on the Prince, who, it seems, is ruled at present by Lady Holbert, [Hertford?] who, at the age of 60 years, has some secret fascination for his vitiated caprice.
