Mackenzie became so embittered by his defeat in 1836, and the unscrupulous methods by which it was accomplished, that he made up his mind that reform in government was not to be obtained except by a resort to extreme measures. At meetings of Reformers, held at Lloydtown and other places during the summer of 1837, resolutions were carried that it was their duty to arm in defence of their rights and those of their countrymen. Mackenzie visited many parts of the province, in order to stimulate a revolutionary movement among the disaffected people, a system of training volunteers was organised; pikes were manufactured and old arms were put in order. It was decided that Dr. Rolph should be the executive chief of the provisional government, and Mackenzie in the meantime had charge of all the details of the movement. Mr. Bidwell appears to have steadily kept aloof from the disloyal party, but Dr. Rolph was secretly in communication with Mackenzie, Lount, Matthews, Lloyd, Morrison, Duncombe, and other actors in the rebellion. The plan was to march on Toronto, where it was notorious that no precautions for defence were being taken, to seize the lieutenant-governor, to proclaim a provisional government, and to declare the independence of the province unless Sir Francis should give a solemn promise to constitute a responsible council. It is quite certain that Mackenzie entirely misunderstood the sentiment of the country, and exaggerated the support that would be given to a disloyal movement. Lord Durham truly said that the insurrectionary movements which did take place were “indicative of no deep rooted disaffection,” and that “almost the entire body of the Reformers of the province sought only by constitutional means to obtain those objects for which they had so long peacefully struggled before the unhappy troubles occasioned by the violence of a few unprincipled adventurers and heated enthusiasts.”
