This cairn was erected under the supervision of Lieut-Col. Lewis Carmichael of the Imperial Army, then stationed in this district on particular service, by the Highland Militia of Glengarry which had aided in the suppression of the Canadian Rebellion of 1837-38, to commemorate the services of that distinguished soldier Sir John Colborne, who was declared by the historian Napier to have been, 'A man of singular talent for war' and who commanded her majesty's forces in Canada at that critical period. He had previously served with conspicuous merit throughout the Peninsular War and elsewhere and had greatly distinguished himself at Waterloo when in command of the 52nd regiment. He was Lieut. Governor of Upper Canada from November 1828 to January 1836, Governor General of Canada in 1839, and afterwards became Field Marshall Lord Seaton G.C.B. The cairn was repaired and this tablet erected in 1905.
