It is the writer's intention to speak first of two expeditions to Chicago, for the release of the prisoners confined there. The first of these took place during the Chicago Democratic Convention, when it was hoped that the rebels from Canada and their sympathizers from Missouri, Kentucky, Indiana and Illinois, who came armed to assist them in their projects, would be enabled to go quietly into the city without fear of detection, in the vast crowds who were then assembling there, from all parts of the United States, and under the guise of friendly visitors, were to be ready at a moment's notice whenever their leaders called upon them to spring out before the people in their true light, and effect the release of those rebels confined at Camp Douglas. As early as the twenty-fourth and twenty-fifth of August last, at the request of Jacob Thompson, secretly and quietly circulated all through the Canadas, Nova Scotia and New Brunswick, all the Rebels, Skedadlers, Refugees, and others who could be relied upon to take part in the expedition, began to assemble in Toronto, Canada West, at the different hotels and boarding houses; of these, at that time, it was generally reported that there were about three hundred; but so far as positive evidence goes, out of this number only about seventy-five men were induced to join this expedition and go to Chicago. At Toronto the objects of the expedition were made known to nearly all of them, and arms furnished them--_arms manufactured in New York city and shipped to Canada for that express purpose_.

They were all pledged to fight to the last, and never under any circumstances surrender, as their lives would be forfeited, if caught. The whole expedition was under the charge of Capt. Thomas H. Hines, who had a commission as Major-General in the Rebel army, to take effect and date from the release of the rebel prisoners of war at Rock Island or Camp Douglas. Hines is the person who is said to have effected the escape of General John H. Morgan himself, and others from the penitentiary at Columbus, Ohio, and although it is not generally known in the North or South how Morgan escaped, and there not being one word of truth in his report, he has enjoyed for a long time the reputation of having been the author of it, and of being a desperate shrewd character. The real facts in the case were (and it does not do the service of the
