Thus the so-called "Boston Massacre" wrought for the king a rebuff which he felt perhaps even more keenly than the repeal of the Stamp Act. Not only had his troops been peremptorily turned out of Boston, but his policy had for the moment weakened in its hold upon Parliament. In the summer of 1769 the assembly of Virginia adopted a very important series of resolutions condemning the policy of Great Britain and recommending united action on the part of the colonies in defence of their liberties. The governor then dissolved the assembly, whereupon its members met in convention at the Raleigh tavern and adopted a set of resolves prepared by Washington, strictly forbidding importations from England until the Townshend acts should be repealed. These resolves were generally adopted by the colonies, and presently the merchants of London, finding their trade falling off, petitioned Parliament to reconsider its policy. In January, 1770, Lord North became prime minister. In April all the duties were taken off, except the duty on tea, which the king insisted upon retaining, in order to avoid surrendering the principle at issue. The effect of even this partial concession was to weaken the spirit of opposition in America, and to create a division among the colonies. In July the merchants of New York refused to adhere any longer to the non-importation agreement except with regard to tea, and they began sending orders to England for various sorts of merchandise. Rhode Island and New Hampshire also broke the agreement. This aroused general indignation, and ships from the three delinquent colonies were driven from such ports as Boston and Charleston.
