Stuyvesant, on learning of their arrival, forbade them to land.

He dispatched a vessel and a land force, to capture the Swedish ship the Mercury, and bring it with all the passengers to fort Amsterdam.

Having disposed of her cargo, the vessel and all the Swedish soldiers it bore, were sent back to Europe.
In obedience to orders from home, Stuyvesant erected a fort at Oyster Bay, on the north side of Long island.

In the instructions he received he was enjoined, "to maintain, by force, if necessary, the integrity of the Dutch province, the boundaries of which have just been formally confirmed by the States-General." The Directors added, "We do not hesitate to approve of your expedition on the South river, and its happy termination.

We should not have been displeased, however, if such a formal capitulation for the surrender of the forts had not taken place, but that the whole business had been transacted in a manner similar to that of which the Swedes set us an example when they made themselves masters of fort Casimir.".
