The question of Secord's actual contribution to the British success has been contested. In the early 1920s, historians suggested that Native scouts had already informed FitzGibbon of the coming attack well before Secord had arrived on 23 June. Historian Ernest Cruikshank wrote in 1895 that "Scarcely had Mrs Secord concluded her narrative, when [Ducharme's] scouts came in ... they had encountered the advance guard of the enemy." Later, two testimonials were found which FitzGibbon wrote in 1820 and 1827, which supported Secord's claim. FitzGibbon asserted that Laura Secord had arrived on 22 June (not 23 June), and that "in consequence of this information", he had been able to intercept the American troops.
