Colonel Bankhead writes that of the military and naval preparations of the British on the northern frontier of the United States, he can only state that Fort Mississauga, nearly opposite our Fort Niagara, has been enlarged and strengthened; that permanent and extensive barracks were commenced last summer at Toronto and are probably completed by this time, and that a large vessel for a steamer was being constructed last fall at Niagara City by and for the service of the Government; that the British Government has on Lake Ontario a steamboat commanded and officered by officers of the navy, and is commissioned, he presumes, as a Government vessel; that the authorities of Upper Canada had last summer in their service on Lake Erie two steamboats, which were at first hired from citizens of Buffalo, but which they subsequently purchased, as he was informed.

Lieutenant-Colonel Crane writes from Buffalo that the only military work in that vicinity undergoing repairs (within his knowledge) is Fort Mississauga, at the mouth of the Niagara River, on the Canada side, which the English have been repairing and extending for two years past, and it is believed to be now in a very efficient state; that there have been rumors of armed steamers being built or building at Chippewa, but on inquiry he could learn of none except the ordinary steamboats for the navigation of the lakes.  It has been said, however, that one is building on Lake Ontario by the English, and intended for the revenue service, but he does not know what truth there is in this statement.

Lieutenant-Colonel Pierce reports from Plattsburg that he has no knowledge of any military or naval preparations of the British authorities on the line of frontier adjacent to his command, comprising what is generally called the Lake Champlain frontier, except the introduction of troops at Odletown and Napierville, near the boundary line between New York and Canada, on the west side of the lake, and also the establishment of a line of posts from Missisquoi Bay, on the east side of the lake, along and near to the Vermont frontier as far as the Connecticut River, the erection of a new barrack and fieldwork at St. John, and the repairs and armament of the Isle aux Noix, with increased force at both of these posts; that none of the positions so occupied by British troops are within the claimed limits of the United States; that these military preparations (it has been heretofore understood) have been made by the British authorities to suppress rebellion and insurrection among the Canadian population.

Captain Johnson reports from Fort Brady that he has heard nothing on the subject of the resolution but mere rumors, and that there is no appearance of any works going up anywhere on the Canada side of the St. Marys River.  The files of the Adjutant-General’s Office have been examined, but no further information has been elicited.
