On the 5th of September Gage began fortifying Boston Neck, so as to close the only approach to the city by land. Next day the county assize was to be held at Worcester; but 5,000 armed men, drawn up in regular military array, lined each side of the main street, and the unconstitutionally appointed judges were forbidden to take their seats. On the same day a convention of the towns of Suffolk county was held at Milton, and a series of resolutions, drawn up by Dr. Warren, were adopted unanimously. The resolutions declared that a king who violates the chartered rights of his people forfeits their allegiance; they declared the Regulating Act null and void and ordered all the officers appointed under it to resign their offices at once; they directed the collectors of taxes to refuse to pay over money to Gage's treasurer; they advised the towns to choose their own militia officers; and they threatened the governor that, should he venture to arrest any one for political reasons, they would retaliate by seizing upon the Crown officers as hostages. A copy of these resolutions, which virtually placed Massachusetts in an attitude of rebellion, was forwarded to the Continental Congress, which enthusiastically indorsed them, and pledged the faith of all the other colonies that they would aid Massachusetts in case armed resistance should become inevitable, while at the same time they urged that a policy of moderation should be preserved, and that Great Britain should be left to fire the first shot.
