COMPANIES AT NEW YORK. Three companies from Berks County were in service at New York and in that vicinity in 1776. Two of them formed part of the 5th Battalion of Pennsylvania troops, which was under the command of Col. Robert Magaw, of Carlisle. The captains were John Spohn and Peter Decker, both residents of Reading. The men of Spohn's company were also from Reading, but those of Decker's were mostly from the districts surrounding Reading. George Hoffner. The third company constituted part of the Pennsylvania Rifle Regiment, of which Samuel Miles was appointed Colonel. It was commanded by Capt. Henry Christ, who was also from Reading. Services of Company. The Pennsylvania Rifle Regiment was embodied strictly for the defense of the Province, at the suggestion of the Committee of Safety, on February 20, 1776, when they passed a resolution praying that the House of Representatives order the raising of 2000 men for that purpose. The House acted promptly and on March 4th appointed a committee to estimate the expense of levying a body of 1500 men, victualing and paying them for one year. On March 5th the estimate was reported, and on the same day the levy was made and the men were ordered to be enlisted to serve until January 1, 1778, subject to be discharged at any time. The first two captains were appointed on March 7, 1776 ; the others on the 9th. Daniel Brodhead of Reading was appointed Lieut. Colonel of the 2nd Battalion on March 13, 1776, and Ennion Williams, of Bethel township, was appointed Major of the 1st Battalion on the same day, both of whom afterward became prominent in the Revolution. The regiment was raised in about six weeks and rendezvoused at Marcus Hook. On July 2nd it was ordered to Philadelphia, when the number of officers and men in Christ's company reported on duty were 62; on the 4th to Bordentown, on the 5th to Trenton, and thence to Amboy under orders to join General Mercer, which it accomplished by the 16th. On August 1st, a report of the company showed 64 on duty. On August 10th, the regiment was ordered to New York under the command of Brig.-Gen'1 Lord Sterling. According to a general return on the 24th, 867 officers and men of this rifle regiment were present.
