Mr. Seward to Mr. Clay

No. 208.]

Sir: In an interview with Mr. Edward de Stoeckl, we have received an official confirmation of the exciting report that on the 4th of April last an unsuccessful attempt was made to assassinate his Majesty the Emperor of Russia.

This intelligence is received by the President of the United States with profound concern. That concern is increased by the circumstance, apparently authentic, that the infamous attempt was perpetrated from motives of revenge against the government of Russia for its successful suppression of slavery throughout the empire. In every respect, then, except in its failure, this crime is paralleled with that of the assassination of our late and lamented President Abraham Lincoln.

The President desires that you will ask a personal interview with his Majesty, and in the name of the United States congratulate him upon the escape which Divine Providence vouchsafed to him, and assure him of the sincere respect, affection, and friendship of the American people.

I am, sir, your obedient servant

WILLIAM H. SEWARD.

Cassius M. Clay, Esq., &c., &c., &c.
