"The Cornwalliad, an Heroic Comic Poem," was begun in March, 1779, and was continued through several numbers. It described various incidents in the British retreat to New York after the battles of Trenton and Princeton. In the January number was begun a series of articles under the title of "The Cave of Vanhest," concerning which the following letter was written October 2, 1779, by Mrs. Sarah Bache to Benjamin Franklin: "The publisher of _The United States Magazine_ wrote to you some time ago to desire you would send him some newspapers, and sent you some of his first numbers. I suppose you never received them. I now send six, not that I think you will find much entertainment in them, but you may have heard that there was such a performance, and may like to see what it is; besides, its want of entertainment may induce you to send something that may make the poor man's magazine more useful and pleasing. Tell Temple 'The Cave of Vanhest' is a very romantic description of Mr. and Mrs. Blair's house and family; the young ladies that the traveller describes and is in love with are children, one seven months younger than our Benjamin, and the Venus just turned of five." The most amusing episode in the history of the magazine was the quarrel that arose between its editor and General Charles Lee. Brackenridge published in full, in Vol. I, p. 141, a letter written by "an officer of high rank in the American service to Miss F----s (Franks), a young lady of this city." The letter contained a humorous challenge growing out of a merry war in which Miss F. had said that "he wore green breeches patched with leather," and the writer declared that he wore "true sherry vallies," that is, trousers reaching to the ankle with strips of leather on the inside of the thigh. Lee immediately published in the _Pennsylvania Advertiser_ an angry letter upon "the impertinence and stupidity of the compiler of that wretched performance with the pompous title of the magazine of the United States." In reply, Brackenridge compared Lee, as usual, to his favorite ourang-outang, and added: "You are neither Christian, Jew, Turk nor Infidel, but a _metempsychosist_! You have been heard to say that you expect when you die to transmigrate to a Siberian fox-hound, and to be messmate to Spado." Upon this Lee, in a rage, called at the office with the intention of assaulting the editor. Brackenridge's son cleverly relates what followed. General Lee "knocked at the door, while Mr. Brackenridge, looking out of the upper-story window, inquired what was wanting. 'Come down,' said he, 'and I'll give you as good a horse-whipping as any rascal ever received.' 'Excuse me, General,' said the other, 'I would not go down for two such favors.'"
