The detachment of the 19th Light Dragoons arrived in Lower Canada and was sent forward into the Niagara Peninsula of Upper Canada serving in 1813 at the blockade of Fort George, the Fort George Reconnaissance, at the destruction of Black Rock and Buffalo in New York State. During 1814, they were at Chippawa, Lundy's Lane and at the siege of Fort Erie. During the early stages of the American invasion of Canada in July 1814, participated in Col Thomas Pearson's smart delaying action against Brigadier General Winfield Scott's brigade and fought a a sharp encounter against American infantry in which a troop of the 19th Light Dragoons charged down on the infantry who were trying to capture two British field pieces. Eight horses were knocked down and four dragoons were wounded by the Americans, but the guns were safely withdrawn into the British lines. There was also an element of the 19th Light Dragoon's detachment that accompanied the Plattsburgh campaign.

A dismounted detachment of the 14th Light Dragoons served in the New Orleans campaign.

It should be noted that the various British lancer regiments came about in 1816, during the post-war reorganization of the British cavalry, in which several regiments were converted to the lancer roll. The utility of the lance had become all to clear during the war and these units soon adopted Polish style dress as well. The first volume of Anglesey's multi-volume history of the British cavalry covers this topic well.
