James E. Harvey to William H. Seward, April 7, 1865

Mr. Harvey to Mr. Seward

Sir: I have now the honor to communicate a copy of the note of the Duke de Loulé in reply to the representation regarding the indignity and violence offered to the United States steamer Niagara, by the governor of Belem castle, on the 28th of March, and of my acknowledgment and acceptance of the same.

It should be stated in this connexion that the flag of the United States was raised above the main tower of Belem castle yesterday at noon, and formally saluted with twenty-one guns. The Niagara returned the salute as an act of courtesy. This was the first occasion upon which the flag of a foreign nation ever floated over the tower of Belem, it being reserved exclusively for the royal standard. A flagstaff is erected upon the lower part of the castle for salutes of ceremony.

I have the honor to be, sir, your obedient servant,
