The fort was surrounded; and frequent and violent attacks were made upon it, especially in the night, when it was almost impossible for the garrison to defend themselves. Many bloody single combats took place in which the enemy generally fell, for in bodily prowess a Swede was always superior to any one of the attacking force. But no matter how many assailants were killed, the main body seemed as powerful and determined as ever. In course of time the valiant Swedes were obliged to give way before their enemy. They struck their flag, evacuated the fort, and departed entirely from the place where they had hoped a flourishing settlement would spring up under the protection of their fort. The enemy which attacked and routed the Swedes was a large and invincible army of mosquitoes, against whom their guns, their pistols, their swords, their spears, and their ramparts afforded them no defense. After that, the deserted fort was known as Mygenborg, meaning Mosquito Fort. The Dutch looked with great disfavor on the Swedes, who continued to establish themselves at various points; and although they did not make an alliance with the body of natives who had driven these northern people away from Elsinburgh,--for a compact of that kind would be dangerous in many ways,--they took up the matter by themselves; and finally the Dutch, under their valiant Peter Stuyvesant, completely conquered the Swedes, and sent their leaders to Holland, while the ordinary settlers submitted to the Dutch. But this state of things did not continue very long; for the English, who, although they had not yet settled in New Jersey, had never given up their pretensions as the original discoverers, came in strong force, subdued the Dutch, occupied their principal town, New Amsterdam, and took possession of the country, including New Jersey. But it seemed to be a good deal easier to discover New Jersey than finally to settle its ownership. Now that the Dutch and the Swedes were disposed of, there arose difficulties regarding the English claims to the State. Early in the seventeenth century, Queen Elizabeth had granted an immense tract of land to Sir Walter Raleigh, which was called Virginia, and that included the whole of New Jersey. Afterwards Charles II. granted to his brother, the Duke of York, an immense tract of land, which also included New Jersey, and which was called New York. So what is now New Jersey was then at the same time both Virginia and New York. The Duke of York, who then owned New Jersey, leased the whole State--lands, forests, rivers, wigwams, Indians, fisheries, Dutch settlers, Swedish settlers, everything--to John Berkeley (Baron of Stratton) and Sir George Carteret for the sum of twenty nobles per year (thirty-two dollars of our money). Some authorities, indeed, state that the sum paid was much smaller.
