Sir William Phips, under instructions from Whitehall, built a new fort at Pemaquid in 1692, which he called William Henry. Captains Wing and Bancroft were the engineers, the work being completed by Captain March.[54] The English believed it impregnable. Mather, who says it was the finest that had been seen in those parts of America, has a significant allusion to the architect of a fortress in Poland whose eyes were put out lest he should build another such. From this vantage-ground the English, for the fifth time, obtained possession of Acadia. In the same year D'Iberville made a demonstration against it with two French frigates, but finding an English vessel anchored under the walls, abandoned his design, to the chagrin of a large band of auxiliary warriors who had assembled under Villebon, and who now vented their displeasure by stamping upon the ground. The reduction of Fort William Henry was part of a general scheme to overrun and destroy the English settlements as far as the Piscataqua. The English were fore-warned. John Nelson, of Boston, whose biography is worth the writing, was then a prisoner at Quebec. Madocawando was also there, in consultation with Count Frontenac. The Abenaqui chief, dissatisfied with his presents, gave open expression of his disgust at the niggardliness of his white ally. Nelson was well acquainted with the Indian tongue. He cajoled the chief into talking of his projects, and as soon as they were in his possession acted like a man of decision. He bribed two Frenchmen--Arnaud du Vignon and Francis Albert--to carry the intelligence to Boston. On their return to Canada both were shot, and Nelson was sent to France, where he became for five years an inmate of the Bastile. [Illustration: FRENCH FRIGATE, SEVENTEENTH CENTURY.] The life of John Nelson contains all the requisites of romance. Although an Episcopalian, he put himself at the head of the revolution against the tyranny of Andros. As a prisoner, he risked his own life to acquaint his countrymen with the dangers that menaced them; and it is said he was even carried to the place of execution along with his detected messengers. The French called him "le plus audacieux et le plus acharné," in the design of conquering Canada. Released from the Bastile on his parole, after visiting England he returned to France to fulfill its conditions, although forbidden to do so by King William. A man of address, courage, and high sense of honor was this John Nelson. In 1696, a second and more successful expedition was conducted against Pemaquid. In August, D'Iberville[55] and Bonaventure sailed with the royal order to attack and reduce it. They called at Pentagoët, receiving there a re-enforcement of two hundred Indians, who embarked in their canoes, led by St. Castin. On the 13th the expedition appeared before the place, and the next day it was invested.
