The first battalion of the THIRTY-NINTH regiment arrived at Quebec on the 5th of August, and marched from thence to Chambly. After the arrival of the reinforcements from Europe, the Governor-General of Canada, Lieut.-General Sir George Prevost, Bart., assembled all the disposable forces in the lower province for an attack upon the state of New York. On the 2nd of September the first battalion of the THIRTY-NINTH, with the other corps employed on this service, proceeded towards the United States to co-operate with the naval force on Lake Champlain. As the troops approached the line of separation, the Americans abandoned their entrenched camp on the river Chazy, and this post was occupied by the British on the 3rd of September. The first battalion remained at Chazy to keep up the communication, having sent forward the light company to _Plattsburg_, a fortified place on Lake Champlain; two officers and sixty men of the THIRTY-NINTH were detached on board the fleet to act as marines. The attack was made on the morning of the 11th of September; but the defeat of the British naval force on the lake rendered it necessary to abandon the enterprise, as the most complete success on shore would have proved unavailing after the loss of the shipping. The troops accordingly retired to Lower Canada. [Sidenote: 1815. 1st Batt.] After the failure of these operations the first battalion returned to Chambly, where it remained until the 27th of May 1815, and then proceeded to embark at Quebec under the command of Brevet-Lieut.-Colonel Patrick Lindesay, its services being again required in Europe in consequence of the return of Napoleon Bonaparte to France, who resumed his former title of Emperor of the French, but which assumption the Allied Powers refused to recognise. The first battalion sailed from the river St. Lawrence on the 12th of June, and arrived at Portsmouth on the 15th of July. Meanwhile the destiny of France had been decided on the field of Waterloo, and Louis XVIII. had been again restored to the throne. The battalion proceeded on the 18th of July for Ostend, disembarked on the 21st, and immediately marched to join the British army at Paris. On the 26th of August it was reinforced by a strong detachment from the second battalion under Lieut.-Colonel Cavendish Sturt, who assumed the command. [Sidenote: 2nd Batt.] In April 1815 the second battalion was removed from Weymouth to Winchester Barracks, and, after having transferred all the effective men to the first battalion, was disbanded at the latter place on the 24th of December following. The regiment remained near Paris until the Army of Occupation was formed, and on the 27th of December 1815 marched to take up the cantonments appointed for it in the Pas-de-Calais, between the towns of Arras and St. Pol, moving annually to the camps of St. Omer and Valenciennes until the breaking up of the Army of Occupation in 1818.
