There still remain, however, a round score of thorns in his militant flesh, being as many captains and lieutenants, who are better qualified for the drawing-room than the field. He must rid himself of this element of popinjay. Since young Aaron is clothed of no power of dismissal over the offensive popinjays, the situation bristles with difficulties. For all that they must go. After one night’s thought, he gets up from his cogitations inclined to exclaim, like another Archimedes: “I have found it!” Young Aaron’s device is simplicity itself. Having no power of dismissal, he will usurp it. Also, he will assert it in such fashion that not a popinjay of them all will be able to make his dismissal the basis of military inquiry, and keep his credit clean. Young Aaron writes, word for word, the same letter to each of the undesirable popinjay ones. He words it, skillfully, in this wise: _Sir: You are unfitted for the duties you have assumed. For the good of the service therefore, I demand the immediate resignation or your commission. To be frank, sir, I think you lack the courage to lead your men in the presence of a foe. Should I be wrong in this assumption, you of course will demonstrate that fact by methods which readily suggest themselves to every gentleman of spirit. Let me therefore urge that you either forward your resignation as herein demanded by me, or dispatch in its stead a request for that satisfaction which I, as a man of honor, shall not for one moment deny. I beg leave to remain, sir,_ _Your very humble servant,_ _Aaron Burr, Acting Colonel._ “There!” thinks he, when the last letter is signed, sealed, and sent upon its way to the popinjay hand for which it is designed, “that should do nicely. I’ve ever held that the way to successfully deal with humanity is to take humanity by the horns. That I’ve done. Likewise, I flatter myself I’ve constructed my net so fine that none of them can wriggle through. And as for breaking through by the dueling method I hint at, I shall have guessed vastly to one side, if the best among them own either the force or courage to so much as make the attempt.” Young Aaron is justified of his perspicacity. The resignations of the popinjays come pouring in, each seeming to take the initiative, and basing his “voluntary” abandonment of a military career on grounds wholly invented and highly honorable to himself. No reference, even of the blindest, is made to that brilliant usurpation of authority. Neither is young Aaron’s letter alluded to in any conversation.
