This new mode of warfare, or incendiarism, as it is generally called, was first started by the rebel government, after the fall of Memphis, Tenn., for the purpose of destroying vessels, loaded with government property, and cut off the communications of the armies in the lower countries, with their depots of supplies; with this end in view, companies of men were regularly enlisted for the purpose, and after a time, the sympathies and the aid rendered the rebellion by certain classes of the people at the North, justified them in extending its pernicious effects further North. Companies were enlisted and sent through the lines, with orders to burn public buildings, army stores, and supplies, wherever they could find them. Thus far, secret agents of the rebels were scattered all over the North, in small squads, wherever there was a prospect of doing injury to the government; and it is to the efforts of these men, that the country is indebted for the wholesale destruction of steamboat and other property at St. Louis, Cairo, and other places on the western rivers. These men performing the incendiary acts frequently upon information furnished them by their sympathizing friends. The public are already well aware of the manner in which some of these acts of incendiarism terminated, most especially the attempt of Capt. Kennedy and others, holding commissions in the rebel service, to burn New York city. If ever a man deserved his fate, this man Kennedy certainly did, and the public, having been saved, unscathed, can never fully appreciate the enormity of his crime. One, knowing the facts of these men being in the North for this purpose, can readily appreciate the punishment awarded them; but upon reviewing all the facts in the case, will as readily say that they are now less guilty than the citizens of the North, who aided them in their designs, by furnishing them information and associating with them, and even receiving them into their families, while they were yet public enemies, and in arms against the country.
