line of that frontier, Coteau du Lac was _occupied and fortified_; and had it not been for the defeat which part of General Dearborn's army met with from Lieutenant-Colonel Morrison's division in descending the St. Lawrence, that post would have presented a formidable obstacle to the advance of the enemy. The importance of Isle aux Noix, as a post, has been considerably lessened[24] since the defence of the Canadas by the French, in consequence of the facility with which Lower Canada may now be entered by the various routes which the intercourse between that Province and the United States has created. Isle aux Noix had long ceased to be either the only, or principal barrier between the two countries. The occupation of this post was not therefore deemed necessary as a precautionary measure before the war; nor was it until some time afterwards that Sir George Prevost was enabled to put it in a state of defence. As soon, however, as the reinforcements and supplies from England gave him the means of more effectually guarding all the avenues to the Lower Province, Isle aux Noix became the object of his consideration. In consequence of the condition in which it was then placed, and of the force stationed there, two armed schooners of the enemy fell into our possession, and laid the foundation of the marine which was afterwards formed for carrying forward the operations on Lake Champlain. There cannot be a stronger proof of the little importance which the enemy themselves attached to this post in the early part of the contest, than their never making the slightest attempt to obtain possession of it. Having thus stated what Sir George Prevost did _not_ do, by way of preparation for the defence of the Canadas before the war, the Reviewer proceeds to point out what _was_ done by him after the commencement of hostilities. And here we find the same want of candour which distinguishes the remarks to which we have already adverted.[25] In order to form a correct opinion of Sir George Prevost's conduct at this period, it will be necessary to advert to the system which he adopted on the commencement of the war, and to the motives which induced him to pursue it.
