Mr. Seward to Lord Lyons.

My Lord: Recurring to your communication of the 24th ultimo in relation to the imprisonment in Fort Warren of Mr. Cory the master, and Mr. Perries the chief officer, and three of the crew of the British steamer Don, I have now the honor to enclose, in reply, a copy of a letter of the 1st instant from the Secretary of the Navy, stating that their release has been ordered, and that measures are being taken for the discharge of all bona fide foreign subjects captured in neutral vessels seized for breach of blockade, where there is no other charge against them warranting their detention, and they are not needed as witnesses.

I have the honor to be, with high consideration, my lord, your obedient servant,

WILLIAM H. SEWARD.

Right Hon. Lord Lyons, &c., &c., &c.

Mr. Welles to Mr. Seward.

Orders have been given for the release of the persons referred to, and measures are being taken for the discharge of all bona fide foreign subjects captured in neutral vessels seized for breach of blockade, where there is no other charge against them warranting their detention, and they are not needed as witnesses.
