Hon. JOHN FORSYTH, etc.

SIR:  With reference to the letters which, by direction of the President, you addressed to me on the 5th and 19th ultimo, respecting the capture and destruction of the steamboat Caroline by a Canadian force on the American side of the Niagara River, within the jurisdiction of the State of New York, I have now the honor to communicate to you the copy of a letter upon that subject which I have received from Sir Francis Head, lieutenant-governor of the Province of Upper Canada, with divers reports and depositions annexed.

The piratical character of the steamboat Caroline and the necessity of self-defense and self-preservation under which Her Majesty’s subjects acted in destroying that vessel would seem to be sufficiently established.

At the time when the event happened the ordinary laws of the United States were not enforced within the frontier district of the State of New York.  The authority of the law was overborne publicly by piratical violence.  Through such violence Her Majesty’s subjects in Upper Canada had already severely suffered, and they were threatened with still further injury and outrage.  This extraordinary state of things appears naturally and necessarily to have impelled them to consult their own security by pursuing and destroying the vessel of their piratical enemy wheresoever they might find her.

I avail myself of this occasion to renew to you the assurance of my high respect and consideration.

H.S.  FOX.

TORONTO, UPPER CANADA, January 8, 1838.

His Excellency HENRY S. FOX,

Her Majesty’s Minister, Washington.

SIR:  I have the honor to inclose you the copy of a special message sent by His Excellency Governor Marcy to the legislature of the State of New York, in relation to a matter on which your excellency will desire the earliest and most authentic information.  The message only reached this place yesterday, and I lose no time in communicating with your excellency on the subject.

The governor of the State of New York complains of the cutting out and burning of the steamboat Caroline by order of Colonel McNab, commanding Her Majesty’s forces at Chippewa, in the Province of Upper Canada, and of the destruction of the lives of some American citizens who were on board of the boat at the time she was attacked.

The act complained of was done under the following circumstances: 

In Upper Canada, which contains a population of about 450,000 souls, the most perfect tranquillity prevailed up to the 4th day of December last, although in the adjoining Province of Lower Canada many of the French Canadian inhabitants had been in open rebellion against the Government for about a month preceding.

At no time since the treaty of peace with the United States in 1815 had Upper Canada been more undisturbed.  The real causes of the insurrection in Lower Canada, namely, the national antipathy of the French inhabitants, did not in any degree apply in the upper Province, whose population, like the British and American inhabitants of Lower Canada, were wholly opposed to the revolt and anxious to render every service in their power in support of the Queen’s, authority.
