When the vessel arrived at Philadelphia, in March, 1803, Etienne was astonished to find that Anslong had paid his passage, and claimed him as his slave. Dennis Cottineau showed the receipts for the passage money, and written directions to forward the _three_ slaves to New-Jersey. In this dilemma, he asked counsel of a colored man, whom he had formerly known in Guadaloupe; and he immediately conducted him to Isaac T. Hopper. He related the particulars of his case very circumstantially, and the two colored men, who were really the slaves of Anslong, confirmed his statement. When Friend Hopper had cautiously examined them, and cross-examined them, he became perfectly satisfied that Etienne was free. He advised him not to leave the city, and told him to let him know in case Dennis Cottineau attempted to compel him to do so. He accordingly waited upon that gentleman and told him he had resolved not to submit to his orders to go to New-Jersey. Whereupon Cottineau took possession of his trunk, containing his papers and clothing, and caused him to be committed to prison. A writ of _habeas corpus_ was procured, and the case was brought before Judge Inskeep, of the Court of Common Pleas. It was found to be involved in considerable difficulty. For while several witnesses swore that they knew Etienne in Guadaloupe, as a free man, in business for himself, others testified that they had known him as the slave of Anslong. It was finally referred to the Supreme Court, and Etienne was detained in prison several months to await his trial. Eminent counsel were employed on both sides; Jared Ingersoll for the claimant, and Joseph Hopkinson for the defendant. A certificate was produced from the municipality of Guadaloupe, showing that Etienne had been an officer in the French army for several years, and had filled the station in a manner to command respect. The National Decree abolishing slavery in that Island was also read; but Mr. Ingersoll contended that when the decree was revoked, Etienne again became a slave. In his charge, Judge Shippen said that the evidence for and against freedom was about equally balanced; and in that case, it was always a duty to decide in favor of liberty. The jury accordingly brought in a unanimous verdict that Etienne was free. The court ordered him to refund the twenty dollars, which Anslong had paid for his passage; and he was discharged.
