On the 9th of September, A. D. 1851, Mr. Edward Gorsuch, a citizen of Maryland, residing near Baltimore, appeared before Edward D. Ingraham, Esq., U. S. Commissioner for Philadelphia, and asked for warrants under the Act of Congress of the 18th Sept. 1850, for the arrest of four of his slaves whom he had heard were secreted somewhere in Lancaster County. Warrants were issued forthwith, directed to H. H. Kline, a deputy U. S. Marshal, authorizing him to arrest George Hammond, Joshua Hammond, Nelson Ford, and Noah Buley, persons held to service or labor in the State of Maryland, and bring them before the said Commissioner. Mr. Gorsuch then made arrangements with John Agin and Thompson Tully, residents of Philadelphia, and police officers, to assist Kline in making the arrests. They were to meet Mr. Gorsuch and some companions at Penningtonville, a small place on the State railroad, about 50 miles from Philadelphia. Kline, with the warrants, left Philadelphia, on the same day about 2 P. M. for West Chester. Here he hired a conveyance and rode on to Gallagherville. Here he hired another conveyance to take him to Penningtonville. Before he had driven very far, the carriage breaking down, he returned to Gallagherville, procured another and started again. Owing to this detention, he was prevented from meeting Mr. Gorsuch and his friends at the appointed time. When he reached Penningtonville, about 2 A. M., on the 10th September, they had gone. On entering the tavern, the place of rendezvous, he saw a colored man whom he recognized as Samuel Williams, a resident of Philadelphia. To put him off his guard, Kline asked the landlord some questions about horse thieves. Williams replied that he had seen them, and told Kline he had come too late. Kline then drove on to the Gap. Seeing a person he believed to be Williams following him, he stopped at several taverns along the road to make inquiries about horse thieves. He reached the Gap about 3 A. M., put up the horses and went to bed. At half past four he got up, ate breakfast, and rode to Parksburg, about 45 miles from Philadelphia, on the same railroad. Here he found Agin and Tully asleep in the bar room. He awoke Agin, called him aside, and inquired for Mr. Gorsuch and his party. He was told they had gone to Sadsbury, a small place on the turnpike, four or five miles from Parksburg.
