OCT. 23. . . . . die contest terMitiate . so unpropitiously, the Com mander in Chief ordered a retreat. Our loss in the naval attark is estimated at 170, in killed ond wounded. In the land attack, the private accounts rate it at 800 men. Considerable dissatisfac!ion is said to prevail relative to this retreat. Some private letters declare, that one General bad been put under' arrest, that . two others had tendered their resignations. The army had, at the latcit date of the advices (the f 7th ult.) returned to nearly the same positions as those which they occupied previous to the attack on Platt:- burg. Considerable loss of provisions and ammunition had been sus'ained in the ret eat. The following ig the British official account of the late operations on Lake Chainplain and at Plattsburg:— 48 llead-quarters, Odell Town, Sept. 13. GENERAL ORDER. " The pummander of the Fo-c'ss 1111% if) thank the left division for the steady discipline, unwearied exertions, end gallantry, which have marked its short .service to the territory of the enemy, so unfortu nately prreated in its course by the disastruts fat.- of the flotilla ; that bad advaT, rd to cu—perat- in the ulterior object of the campeigi The intrepid valour with which Captain Downie led his flotilla into ac. lion, encouraiec ttie most sanguine hope of complete success, which was early !:lasted by tne fell of that g Mani officer, combined with ac cidents to which naval warfare are pet uliarlN exposed, in consequence of the rudder of his . lllttjest . y's ship Cottft ace being disabled, and the brig Linnet grounding early in the acties . ; thus leasing those ill-fated vessels almost wi•t:out resource, exposed to the wit rle force of the enemy. All I. at undaunted devotion to the service could t Get, was evinced on this 'unfortunate occasion. The officer in command of the divisioo of Run-ooats, acted with judgment, in securing these vessels to the service, when his further efforts in action had become un- availing. " The high spirit and conduct displayed by his Majesty's troops in surmounting every obstacle to the occupation of Plattsburg, end in af terwards forcing the pxo-age of the Saranac, leaves no daub: in the mind of the C2mmander of the Forces,- thr:t the .most complete and brilliant success would love crowned their ulterior operations, had not the existing circumstance imperiously imposed upon him the necesity of reAraining their ardour, as without naval co-operation the further prosecution of the service . would have been highly inexpedient. " The Commander of the Forces avails himself of this opportunity to acknowledge the sense he entertains of the cordial support he has . experienced from Major General be Hottenburg r and the Major Ge nerals commanding triodes. " The orderly nasrch made by the left division iii re-occupying the podion it had . adviinced from on the 4th inst. notwithstanding the iu. Clemency of the weather, and the very wretched state of the roads, evinces, in the strongest manner, the judicious arrangements of the Quarter Master General and Commissary General, as well as the Ull• vearied attention of the commanding officers of corps to their ditti'. " The Commander of the Forces has to expr( as his'entire approb.:• ti n of the arrangements and zealous exertions of Major !Sinclair, and the officeis of the of al Artillery ; nor is tie disposed to overlook the alacrity and intelligence of the junior oflice.s ot . the Ito 3a! Engineeis, who ate thereby entitled to his acknowledgments. His Excellency feels it a just tribute due to the Canadian Voltigeurs ano C asseurs, publicly to notice the report of Major General Brisbane, tl„it the con du( t of these corps, in their peculiar duties of light troops, has on every occasion been conspicuously judiciou , and gallant. (Signed) E. BAY YE':, Adj. Gen. N. A. The disastrous -new; from Lake Champlain and Platts burgh, and the - failure of our expediticu against Baltimore, will raise the drooping spirits of the Americans.' After the gallant •achievement•at Washington, the public were not pre pared for such •unfortunate events. The destruction of out flotilla took place three'days before the tuettihg of Congress, ( • which, wilt give Mr. Madison an opportunity of rallying Lis dispirited partisans, and of encouraging the democratic fac tion to persis' in the war, in case the force under Co:onel Brooke does nrA perform some new exploit. Halifax Papers have been received to the 25tb —They are filled with details of our operations in the Potomac and Chesapeake. The principal article of their contents, is a pro climation issued by Sir John Sherbrooke and Admiral Grif fith, at Halifax, on the 21st ult, in which they announce that they have taken formal possession fur his Majesty of all the eastern side of the Penobscot, and the country 12:ill between' that river and *the boundary line of the Province of. New Brunswick, including Long and other islands. They have established a Provisional Government till his Majesty's plea sure be known, and appointed Major General Gosselin Go vernor. They require all persons to take oaths not to bear arms against his Majesty, and promise them protection Tor their persons and property. They give leave fur lititish produce to, be imported in British ships into the pit of Cus tine, and no Wier port. By this Proclamation it thus offi cially appears that our Government require a new boundary line to Canada. By the arrival of the Calypso, we lament to learn, that the b:.ats of the Plantagenet, liota, and Carnation, had at tacked the General Armstrong American privateer in the port of Fayal, and were beaten off, with the loss of Lieute nants Matterface and Norman, of the Rota, killed; awl Lieutenant Bowerbank, of the Plantagenet, shot through his lungs altogether we suffered a loss of 133 killed and wounded. The crew abandoned her immediately after the attack, and the Carnation was sent in and burnt her. Frankfort Papers to the 15th instant, and Brussels 'to the 191 b, have reached town. The intelligence from Vienna,. in these Journals intimates, that the Congress would not openly meet till the 18th, but that the conferences conti nued in the mean time in a sort of secret Congress.
