Mr. Welles to Mr. Seward .

Sir: I have the honor to acknowledge the receipt of your letter of the 19th instant and enclosures, and to transmit herewith a copy of a report of Captain William W. McKean, commanding United States ship Niagara, and a copy of a report of Commander Melancton Smith, which contain such information as the department possesses in relation to the seizure of the British ship “Perthshire” by the United States steamer Massachusetts, and her subsequent release by order of Captain McKean.

I am, respectfully, your obedient servant,

GIDEON WELLES.

Hon. William H. Seward,
Secretary of State.

Captain McKean to Commodore Mervine .

Sir: Your communication of the 17th instant, with the accompanying document, was received on the 18th instant.

The English ship “Perthshire,” Captain James Oates, left the harbor of Mobile on the 30th of June, 1861, and was boarded by Lieutenant Spicer, from this ship, and passed by my order, the fifteen days allowed by the proclamation of the President of the United States for neutral vessels to depart not having expired.

I am under the impression that no indorsement was made upon her register, as I did not consider it necessary.

I arrived off Fort Pickens in the Niagara early on the morning of the 12th of June, 1861. A large ship, which proved to be the “Perthshire,” had just anchored.

Immediately after the Niagara had come to anchor, Commander M. Smith, commanding the United States steamer Massachusetts, came on board and reported having captured the Perthshire in latitude 27° 27′ and longitude 85° 31′.

I stated to Commander Smith that the Perthshire had left Mobile within the time allowed by the President’s proclamation; that I considered the capture illegal, as, by order of the department, no neutral vessel not having on board contraband of war, was to be detained or captured unless attempting to leave or enter a blockaded port after the notification of blockade had been indorsed on her register. I therefore directed him to release the “Perthshire,” and to replace such provisions and stores as might have been used by the prize crew.

She was accordingly released and immediately got under way, Commander Smith having reported to me that he had not only replaced such provisions as had been used, but had also supplied her with water.

I subsequently received from Captain Adams the report of Commander Smith, a copy of which is herewith submitted. It bears no date.

As I was in hourly expectation of your arrival from Key West, I had fully intended reporting the circumstances to you, but it escaped my memory.

I am, sir, your obedient servant,

WM. W. McKEAN, Captain.

Flag Officer William Mervine,
Commanding Gulf Blockading Squadron,
United States Steam Frigate “Colorado.”

Commander Smith to commanding officer Gulf squadron .

Sir: I have to report that on the 9th instant, in latitude 27° 21′, and longitude 85° 31′, I boarded and seized as a prize the English ship “Perthshire,” from Mobile, bound to Liverpool, with a cargo of 2,240 bales of cotton; said ship having been boarded by one of the blockading fleet off Pensacola, May 13th, and warned not to enter the harbor.

Two officers and twenty-nine men were placed on board the prize, and [Page 181] Mr. Wm. R. Clark, acting master, was directed to proceed with all possible despatch and report to the senior commanding officer of the Gulf squadron for instructions.

In addition to the above, I boarded ship Janico from Mobile, ship Carl and bark Mary from New Orleans, all loaded with cotton, and with registers indorsed; also ship Bramley Moore, from New Orleans, register not indorsed, but allowed her to proceed upon her voyage, as the time granted vessels to clear, according to the notification of blockade, had not expired.

Very respectfully,

MELANCTON SMITH,

Commander.

The Commanding Officer
Gulf Squadron, Pensacola.

[Indorsement by Captain Adams.]

At the time the Perthshire was boarded from this ship and ordered off from Pensacola there was no blockade of Mobile or the Mississippi river.

H. A. ADAMS,
Captain U. S. Frigate “Sabine.”
