Space here exists to notice only the elaborate attacks to which Cooper himself felt constrained to reply. The first of these appeared in four numbers of the "New York Commercial Advertiser" during June, 1839. The articles were written by William A. Duer, who had lately been president of Columbia College. They purported to be a review of the "Naval History," but nothing whatever was said about that work beyond the few pages in which the battle of Lake Erie is described. They were, moreover, so personal in their nature and contained imputations so gross on his character, that Cooper began a libel suit against the journal in which they were published. This finally resulted in one of the most extraordinary trials that has ever been recorded in merely literary annals. The attack in the "Commercial Advertiser" was followed by a similar one in the "North American Review." This was written, however, with more decency, though it again devoted itself mainly to the battle of Lake Erie. It was the work of Alexander Slidell Mackenzie, a naval author, who by three books of travel had gained at the time some literary notoriety. But the notoriety never rose to reputation; and the history which preserves his name at all, preserves it in connection with an event it were well for his memory to have eternally forgotten. It is to be added that he was the brother-in-law of Captain Matthew Perry, and that Duer was his uncle. Hardly had his broadside been delivered, when another attack appeared. The victor of Lake Erie had come from Rhode Island, and Rhode Island rushed to the fray, not to defend her son--for he had not been attacked--but to build up his reputation by (p. 213) ruining that of his enemy. Tristam Burges, when the biography of Elliott, already referred to, had appeared, had delivered a lecture on the battle of Lake Erie before the Rhode Island Historical Society. It was not printed at the time; but no sooner was Cooper's work published than, at the request of Perry's friends and relatives, it was brought out with documents appended. The lecture reads very much like a stump speech of the extreme florid type. It is needless to say that in it Elliott got his full deserts for betraying his commander. It made no direct reference to Cooper, but the whole object was to discredit the account of the battle which he had given.
