Windsor, C.W., the United States authorities had been notified of the expedition, and fully placed upon their guard, and if the plans of Lieut. Col. Hill, the efficient commander of the post at Detroit could have been followed, he would have captured the whole gang. However, he telegraphed to Sandusky, and had Cole arrested while he was sitting at the table, taking dinner with the officers on board the Michigan. This effectually prevented Cole from communicating with the conspirators. Col. Hill's plans were to let the pirates take the _Parsons_, and then before they had time to do any damage, have the Michigan meet them on their way to Sandusky and capture them all together, and thus relieve the Government from any farther trouble with this most desperate band of incendiaries. Col. Hill telegraphed to the commander of the Michigan, requesting him to do this, and it is generally understood that the reason why he did not do it was that the machinery of the vessel was out of order, thus showing how well those who had been bribed had done their duty. In addition to these attempts to capture the steamer Michigan, was the celebrated St. Albans raid, which among others, was one of the rebel modes of carrying the war into Africa and harrassing the northern border. This raid, which has become so famous in the history of this war, was first started by a Texan, named _Bracey_, belonging to one of the rebel Texan regiments. This man, for four or five years before the war, had been going to one of the schools or colleges (according to his own account of himself,) in St. Albans, and was well acquainted, both with the city and country, in the immediate neighborhood. He gave all the information he could, and offered to return there to get more, which he, with one or two rebel soldiers did, and obtained all the necessary information that would, in any way, aid them in their criminal designs. Upon their report, on their return to Canada, the fitting out the expedition immediately began--the money, arms, etc., being furnished by the rebel agents in Montreal or Quebec. Of the details of this affair, as carried out, the people have been fully advised by the newspapers, and, to all intents and purposes, the raid has been a success, or has operated in this manner by the winding and twisting course of the Canadian law courts, which seem to be actuated by no fixed principles, but wavering between the fear of the public opinion of the American people, and their desire to aid the rebels in overturning the government--and had it not been for the sudden turn the war has taken in the last six months, the people along the northern border would have been subjected to numerous other and similar raids. The St. Albans raid was only a part of one grand scheme of the rebels, for the past two years, to inaugurate a new mode of warfare, entirely beyond the pale of that waged by civilized nations, and a relic of the more barbarous ages.
