Before the Dutch had time to call the Swedish intruders to a reckoning Minuet died, and John Prinz was sent out as Governor. There had been the short intervening reign of Peter Hollendare. Prinz came under a cloud, having lost his rank as First Lieutenant by his over-hasty surrender of Chemnitz. Probably this fact may account for his restless energy as Governor of New Sweden. He sought to regain in the new world repute lost in the old. Prinz came with two ships, an armed transport, munitions of war, troops, and many immigrants, and with instructions to maintain and promote piety and education, to develop the resources of the colony, agricultural and mineral, to make friends with the Indians, and to live at peace with all neighboring Europeans. But he was to resent by force of arms, if need be, the pretensions of the Dutch to any territorial or other rights upon the west side of the Delaware. Prinz built at Tinicum, or Tenacong as the Indians called it, near the present city of Chester, Pennsylvania, a fort to threaten the Dutch Fort Nassau, above; and likewise at the mouth of Salem Creek, on the Jersey shore, where the English had a small settlement, he built Fort Elfsborg, or Elsinborough. Both were promptly armed and garrisoned. He built still another fort, this time on the Schuylkill, within gunshot of its mouth, and in 1646 he ordered a Dutch trading-vessel from that river. Furthermore, he caused to be torn down with despiteful words the arms of the Dutch, set up in sign of possession upon the present site of Philadelphia, and when reminded of the Dutch West India Company’s prior claim, he profanely answered that although Satan was the earliest possessor of hell, doubtless he sometimes welcomed new comers. But a day of reckoning was speedily to come, for Peter Stuyvesant, Governor of the New Netherlands, moved by the amazing activity of Prinz, bought from the Indians all the west side of the Delaware from Minquas Creek to Bompties (or Bombay) Hook, and in 1651, as some say,—before the building of Elfsborg as others say,—built Fort Casimir at Sand Huken, now Newcastle, on the Delaware, five miles below Fort Christina, and within sight of Elfsborg. Whichever fort was built first, it is pretty certain that the Swedes soon deserted Elfsborg, after naming it in disgust Myggenborg, which means Fort Mosquito. The excuse for the desertion was the insupportable insect pests of the region; so early did the New Jersey mosquito earn the reputation that clings to him even to this day. As for Prinz, alarmed at the activity of the Dutch, he vainly petitioned the home government for aid, and at length went off to Europe, leaving as deputy his son-in-law, John Pappegoja.
