The arrangements of the vessel did not, however, admit of proper precautions. When two of these men, in company with sixteen other prisoners, were sent down three years after to the penal settlement, there were ten soldiers to guard them: two only were on deck at once. Their prison was railed in, and closed down with triple bolts: the sentinels were doubled, and some sat continually in sight of the prisoners.[176] The pirates proceeded to the Friendly Islands, and thence to the Islands of the Japannese, where seven deserted, and the rest passed towards China. Four seamen presented themselves in a boat, having _Edward_ on the stern, to a vessel at Whampoa, and stated that they had belonged to a lost ship of that name. Swallow was one of them: he was examined by the committee of supercargoes at Canton, and produced a sextant on which was the name of Waldron, of the _Edward_. This name Swallow assumed, and said that he was captain of the _Edward_, of Durham; related his voyages to various ports of South America, the Sandwich Islands, and Japan. Compelled to abandon his vessel, injured by the fire of the Japannese, the crew had divided into parties, of which himself and companions were one. This deposition was forwarded to the company's secretary, and passages were given free to Swallow and three others. A few days after he had sailed, four more appeared: Davis, who gave his name as Stanley, was examined; but he had forgotten the assumed name of the captain, and called him Wilson--this led to minuter inquiries, and he was sent home a prisoner. Information was instantly forwarded, and reached England before Swallow arrived with his companions, and a warrant was issued for their detention: the three were taken, but Swallow had left the ship at Margate, and for a time escaped. Watts, Davis, and Swallow, were ultimately tried for this offence by the Admiralty Court, in London: the two first were executed, and Swallow was acquitted. It is said that the proof of his participation, except by compulsion, was incomplete. The events which led to their conviction were curiously coincident. The Thames police magistrate was unable to proceed, and they might have been discharged; but the police clerk had studied the _Hue and Cry_, and was struck with their resemblance to the description. Popjoy, now in England,[177] pardoned for his good conduct at the capture, had been recently before the magistrate for some trifling offence, and to interest his worship had given the story of the capture, the coracle, and all incidents of his intrepidity. He was thus soon found out by the police, and gave full proof of identity. He stated their crimes, their names, and secret marks which were discovered on their persons: one of them, the very day of the capture, had the figure of a mermaid punctured on his arm. Mr. Capon, the gaoler of Hobart Town, was in London,[178] and thus was able to supply important particulars.
