At a recent date an attack was made on a post of the enemy near Niagara by a detachment of the regular and other forces under the command of Major-General Van Rensselaer, of the militia of the State of New York.  The attack, it appears, was ordered in compliance with the ardor of the troops, who executed it with distinguished gallantry, and were for a time victorious; but not receiving the expected support, they were compelled to yield to reenforcements of British regulars and savages.  Our loss has been considerable, and is deeply to be lamented.  That of the enemy, less ascertained, will be the more felt, as it includes among the killed the commanding general, who was also the governor of the Province, and was sustained by veteran troops from unexperienced soldiers, who must daily improve in the duties of the field.

Our expectation of gaining the command of the Lakes by the invasion of Canada from Detroit having been disappointed, measures were instantly taken to provide on them a naval force superior to that of the enemy.  From the talents and activity of the officer charged with this object everything that can be done may be expected.  Should the present season not admit of complete success, the progress made will insure for the next a naval ascendancy where it is essential to our permanent peace with and control over the savages.

Among the incidents to the measures of the war I am constrained to advert to the refusal of the governors of Maine and Connecticut to furnish the required detachments of militia toward the defense of the maritime frontier.  The refusal was founded on a novel and unfortunate exposition of the provisions of the Constitution relating to the militia.  The correspondences which will be laid before you contain the requisite information on the subject.  It is obvious that if the authority of the United States to call into service and command the militia for the public defense can be thus frustrated, even in a state of declared war and of course under apprehensions of invasion preceding war, they are not one nation for the purpose most of all requiring it, and that the public safety may have no other resource than in those large and permanent military establishments which are forbidden by the principles of our free government, and against the necessity of which the militia were meant to be a constitutional bulwark.

On the coasts and on the ocean the war has been as successful as circumstances inseparable from its early stages could promise.  Our public ships and private cruisers, by their activity, and, where there was occasion, by their intrepidity, have made the enemy sensible of the difference between a reciprocity of captures and the long confinement of them to their side.  Our trade, with little exception, has safely reached our ports, having been much favored in it by the course pursued by a squadron of our frigates under the command of Commodore Rodgers, and in the instance in which skill and bravery were more particularly
