Although he had been treated as an officer of the regular service by John Paul Jones, and had been summoned to attend a court-martial as such, Conyngham decided to return as soon as possible to his own country and sailed in the Experiment for Philadelphia. But most unfortunately his hard luck followed him. When but a few days on the voyage the vessel was captured by the British Admiral Edwards, and within three weeks Conyngham was back once more at Mill prison. But his treatment this time was very different from that which had been accorded him before; and though his spirit chafed at the delay and the confinement, still he was not forced to endure such bodily suffering. In prison, however, he stayed for the rest of the war, and upon his release returned to the United States. [Illustration: Facsimile of Conyngham’s petition to Congress, December 26, 1797.] Almost immediately he sought to have an inquiry made and an accounting rendered for his prize-money and reimbursement for his services, but owing to the condition of affairs that existed at that time it was difficult to get Congress to take any action. There was indeed but little money in the Treasury, and so he was forced to go upon a voyage in a merchant vessel, from which he returned to begin institution of his long suit against Congress for remuneration and redress. And now the tragedy of his life began. For year after year he prayed and petitioned Congress to listen to his plea. Before the matter came actually to trial, good Dr. Franklin was dead. Many witnesses could not be procured, and some of his earlier acquaintances and friends who had not behaved in good faith toward him now deserted him completely. The missing commission would have proved his position, and the search for it became almost the business of his life. A voyage to Europe and a personal investigation of all clues failed to show any trace. It had disappeared as completely as if it had never existed--a fact which some of his enemies asserted to be the case. In this chapter we print a facsimile of his petition to Congress, signed by himself and dated ten years after his first services were rendered. It shows how much hope he had, and yet there is a note almost of despair that rings throughout it. The claim was first submitted to Benjamin Walker by Alexander Hamilton, then at the head of the Treasury, and Mr. Walker failed to perceive any proof of Captain Conyngham’s having been a regularly appointed officer in the service, and for this reason recommended that the claim be not acknowledged. But yet we find him again in 1793 petitioning Alexander Hamilton for redress. In fact, to the day of his death he attempted in every way to have his claim, that he had left to the justice of his country, adjusted and closed up. During the _quasi_ war with France, Conyngham commanded an armed brig named the Maria, and in the War of 1812 he again sought to go to sea, but his health prevented him taking an active part.
