WILLIAM BUTLER was the second of five brothers, all of whom served with distinction in the Revolution and the succeeding wars. Their names were Richard, William, Thomas, Percival and Edward. Thomas, the third brother, is said to have been born in Pennsylvania in 1754, and Richard the elder in Ireland, so that William was either born in America, or came here from Ireland when very young. He was commissioned Lieutenant Colonel October 25, 1776, on the organization of the Fourth Pennsylvania Regiment. Immediately after the battle of Monmouth, in which he bore an important part, his regiment and six companies of Morgan's riflemen were sent to Schoharie County, New York, where he was actively engaged in protecting the frontier settlements from the marauding parties of tories and Indians. After the Wyoming massacre in 1778, as a part of the aggressive policy determined on by Washington, he marched to the Delaware, and descended that stream for two days, and from thence moved across the country to the Susquehanna at Unadilla in pursuit of the enemy, who fled at his approach. From here he moved down to Onoquaga, which was a well built town, with many good farm houses in the vicinity belonging to the tories, located on both sides of the river. He destroyed Onoquaga, and a Tuscarora town lower down, Conihunto eight miles above, and Unadilla, with the grist and saw mill there, the only ones in the valley, and forced the enemy to remove westward to the Chemung where they were found by Sullivan the next year. He was in garrison in the Middle fort of Schoharie during the winter, and in August, 1779, accompanied Clinton down the Susquehanna to Tioga point where he was transferred to General Hand's Brigade August 23d of that year. This was the Colonel Butler to whom General Sullivan entrusted the responsible duties of conducting this important expedition, second only in importance to that of the main army. Two journals give an account of Colonel Butler's march, viz., Thomas Grant, who appears to have been one of the surveying party under Captain Lodge, and George Grant, Sergeant Major of the Third New Jersey regiment, the latter evidently copied from some other journal. PART OF THOMAS GRANT'S JOURNAL. Sept. 20.--This day a detachment of six hundred men with a sufficiency of officers under the command of Col. Wm. Butler were sent into the Cayuga country, with which detachment I was ordered. They marched from Cannadesago at 3 o'clock P.M.
