The main part of the troops in this campaign was dismissed early in July, but about the first of September we find Capt. Sill again in command of a company and marching to the eastward to protect the frontier settlements now threatened by the many hostile Indians who had taken refuge with the tribes in those parts. At Dover, on September 6th, his company, together with that of Capt. Hathorne, found four hundred Indians who were gathered at Dover at Major Waldron's, with whom the neighboring tribes had made peace. The Captains Hathorne and Sill were commissioned to seize and kill all Indians who had been concerned in the war, and there were many of these mixed in with the peaceful tribes and had come hither under their protection and pledge. The Captains urged their commission, and Major Waldron urged his duty and pledge of hospitality; but finding them determined he compromised the matter by planning a stratagem by which some two hundred of the hostile Indians were made prisoners, while Wannalancet and his Pennacooks, Ossipees and Pequakets were allowed to depart unharmed. The account of this transaction will properly fall under the chapter concerning Major Waldron.

Two days after this affair these companies, together with some of Major Waldron's and Capt. Frost's men, marched on to the eastward as far probably as Falmouth, but, finding no enemy and all the settlements deserted or destroyed, they returned to Piscataqua, and were in these parts on October 3d, as mentioned in a letter of Gen. Denison to the Council. Capts. Sill, Hunting and Frost are said to be there under command of Capt. Hathorne. It was there, about this time, that some insubordination or other objectionable conduct occurred, which occasioned the following action of the Court on October 17th, 1676:

I find no explanation of this in any other place, and no subsequent action by the Court concerning Capt. Sill, save that indicated in the answer to the petition below, which appears also in Colony Records, vol. v. p. 506. Mr. Hubbard's account indicates that Capt. Sill still held his command, and went with Capt. Hathorne on the march in November, 1676, to Ossipee and Pequaket. Sometime before November 7, 1681, Capt. Sill removed to Lyme, Conn., where he was living at that date. He died at Lyme, August 6, 1696. His son Thomas was a shipmaster, lived in Boston in 1699, and was probably the Capt. Sill who died there in May, 1709.
