In violation of his oath he issued a treasonable proclamation, in which he said, "You are called upon to abjure the iniquitous government of Peter Stuyvesant over the inhabitants residing on Long Island.

His rule is too grievous for any brave Englishman and good Christian to tolerate any longer.

All honest hearts that seek the glory of God and his peace and prosperity, are exhorted to throw off this tyrannical yoke.

Accept and submit ye then to the Parliament of England; and beware of becoming traitors to one another for the sake of your own quiet and welfare." This proclamation did not meet with a cordial response.

Underbill fled to Rhode Island.
