"Expeditions for the invasion of Canada will rendezvous at Detroit and Rochester, and at Ogdensburg and Plattsburg, and at Portland. The forces assembled at the two first-named points are to operate conjointly against Toronto, Hamilton, and the west of Upper Canada. From Ogdensburg and Plattsburg demonstrations will be made against Montreal, and ultimately Quebec; Kingston will be approached by Cape Vincent, while Portland will be the general place of embarkation for expeditions against the capitals of New Brunswick and Nova Scotia." THE BASES OF OPERATIONS. "The Canadian and provincial borders once crossed, bases of operations will be established in the enemy's country, so that international quarrels with the Washington Government may be evaded. There are to be lands chosen at the head of Passamaquoddy Bay, Saint John's, on the Chambly, close to the foot of Lake Champlain; Prescott, on the Saint Lawrence; Wolfe Island, at the foot of Lake Ontario; Hamilton, Cobourg Goderich, and Windsor, in Upper Canada. These places are all within convenient distances of the United States, and afford by water an easy retreat, as well as cunning receptacles for fresh American levies." THE FORCES AT THE DISPOSAL OF THE FENIANS. "The Irish Republic calculates to have, by the first of April, fifteen millions of dollars at its disposal in ready cash. This will give transportation and maintenance for one month to thirty thousand men, a greater number than were ever before mustered to the conquest of the Canadian possessions. Of this force, eight thousand will carry the line of the Grand Trunk road west of Hamilton; five thousand, crossing from Rochester to Cobourg, will be prepared to move either east, in time to act jointly with three thousand men from Wolfe Island, upon Kingston, or to take part with the western detachment in the capture of Toronto. All this, it is believed, will be the work of two weeks. Thus entrenched securely in Upper Canada, holding all the routes of the Grand Trunk, sufficient rolling stock secured to control the main line, the Fenians hope to attract to their colors fifty thousand American Irishmen, and equip a navy on Lakes Huron, Erie and Ontario. The avenues to return so being secured, thirty thousand men, under General Sweeny, will move down the Saint Lawrence, upon Kingston, simultaneously with ten thousand men by the lines of the Chambly, and these will converge upon Montreal; in the meantime isolated expeditions from the rendezvous at Saint Andrews will reduce Saint John and Halifax, these furnishing depots for privateers and ocean men-of-war to intercept British transports and effectually close the Saint Lawrence. Quebec will thus fall by the slow conquest of time; or, if the resources of the garrison should be greater than the patience of the invaders, the same heights which two Irishmen have scaled before, will again give foothold to the columns of the brotherhood."
