The Dutch West India Company protested and rebuilt Fort Nassau.

The Swedes, in retaliation, went farther up the river and fortified an island near the mouth of the Schuylkill.

Had they stopped here, all would have gone well.

But, made bold by the inaction of the Dutch, they began to annoy the New Netherlanders, till (1655) Peter Stuyvesant, the governor of New Netherland, unable to stand it any longer, came over from New Amsterdam with a few hundred men, overawed the Swedes, and annexed their territory west of the Delaware.

New Sweden then became part of New Netherland.[2] [Footnote 1: Sweden had no right to make such a settlement.
