The regiment moved to Montreal, and took up quarters at the island of St. Helen's, withdrawing the companies at Napierville, but detaching two companies to William Henry, and one to Three Rivers.
During the summer, the regiment suffered severely from ophthalmia, and although situated most favourably (the rapid and clear stream of the St. Lawrence perpetually flowing round the island), and unremittingly watched by the staff and regimental surgeons, the disease was not eradicated.
1840
The service companies returned to England on the 25th June of this year, on board the "Athol" troopship, and disembarked at Portsmouth, where the depôt companies awaited their arrival.
1841
The regiment was quartered at the Haslar and Fort Monckton barracks, until January, 1841, when it marched to Winchester. From thence it was moved to Woolwich in June, detaching three companies to Deptford.
1842
The Fifteenth moved to Windsor early in the month of April, where the regiment remained until November. On being relieved by a battalion of the grenadier guards, the regiment proceeded to Manchester, the head-quarters moving shortly after to Chester Castle.
Whilst stationed at Windsor, the regiment was highly honored by the personal inspection of Her Most Gracious Majesty the Queen, and her August Consort, the Prince Albert.
Her Majesty, on another occasion, reviewed the regiment in the Home Park, attended by H.R.H. the Prince Albert, and the Hereditary Grand Duke of Saxe Coburg Gotha.
