of receiving information from either Secord or FitzGibbon about the impending American attack. Secord wrote two accounts of her walk, the first in 1853, and the second in 1861. Neither account contains details that can be corroborated with military accounts of the battle, such as specific dates or details about troops. Her account changed throughout her life. Historian Pierre Berton noted that she never stated clearly how she learned of the impending attack. She told FitzGibbon that her husband had learned about it from an American officer, but years later told her granddaughter that she had overheard the plans directly from the American soldiers billeted in her home. Berton suggested that Secord's informant could have been an American still residing in the United States, who would have been charged with treason had Secord revealed her source. In the 1860s, as Secord's story gained prominence, historian William Foster Coffin added new details, which included the claim that Laura had brought a cow with her as an excuse to leave her home in case the American patrols questioned her. A number of historians have questioned Secord's account. W. Stewart Wallace, in his 1932 book, The Story of Laura Secord: A Study in Historical Evidence, concluded her story was mostly myth, and that she played no significant role in the outcome of the Battle of Beaver Dams. Historian George Ingram contended in his 1965 book The Story of Laura Secord Revisited that Secord's debunking had been taken too far. Ruth MacKenzie also burnished Secord's reputation with Laura Secord: The Legend and the Lady in 1971. 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. Legacy According to legend, "it took her approximately 17 hours to travel the distance to warn James FitzGibbon of the impending American attack". She has often
