In 1638 Louis XIII. addressed the following letter to D'Aulnay: "You are my lieutenant-general in the country of the Etchemins, from the middle of the main-land of Frenchman's Bay to the district of Canceaux. Thus you may not change any regulation in the establishment on the River St. John made by the said Sieur De la Tour, etc."[35] Three years afterward the king sent his commands to La Tour to return to France immediately; if he refused, D'Aulnay was ordered to seize his person. Whether the death of Louis, and also of his Eminence, at this time diverted the danger with which La Tour was threatened, is a matter of conjecture. D'Aulnay, however, had possessed himself, in 1643, of La Tour's fort, and the latter was a suppliant to the English at Boston for aid to displace his adversary. He obtained it, and recovered his own again, but was unable to eject D'Aulnay from Penobscot. A second attempt, also unsuccessful, was made the following year. The treaty between Governor Endicott and La Tour in this year was afterward ratified by the United Colonies. In 1645 D'Aulnay was in France, receiving the thanks of the king and queen-mother for his zeal in preserving Acadia from the treasonable designs of La Tour. The next year a treaty of peace was concluded at Boston between the English and D'Aulnay; and in 1647, the king granted him letters patent of lieutenant-general from the St. Lawrence to Acadia. He died May 24th, 1650, from freezing, while out in the bay with his valet in a canoe. La Tour finished by marrying the widow of D'Aulnay, thus composing, and forever, his feud with the husband.[36] For some years quiet reigned in the peninsula, or until 1654, when an expedition was fitted out by Massachusetts against Stuyvesant and the Dutch at Manhattan. Peace having been concluded before it was in readiness, the Puritans, with true thrift, launched their armament against the unsuspecting Mounseers of Penobscot. Although peace also existed between Cromwell and Louis, the expenditure of much money without some gain was not to be thought of in the Bay. For a pretext, they had always the old grudge of prior right, going back to Elizabeth's patent of 1578 to Sir Humphrey Gilbert. Robert Sedgwick and John Leverett were two as marked men as could be found in New England. They sailed from Nantasket on the 4th of July, 1654, with three ships, a ketch, and two hundred soldiers of Old and New England. Port Royal, the fort on St. John's River, and Penobscot, were all captured. Afterward they served the Protector in England. Sedgwick was chosen by Cromwell to command his insubordinate and starving army at Jamaica, and died, it is said, of a broken heart, from the weight of responsibility imposed on him.
