later in June before the Battle of Bunker Hill. General Heath studied the position of the British Army and decided to withdraw the militia to Cambridge. Aftermath In the morning, Boston was surrounded by a huge militia army, numbering over 15,000, which had marched from throughout New England. Unlike the Powder Alarm, the rumors of spilled blood were true, and the Revolutionary War had begun. Now under the leadership of General Artemas Ward, who arrived on the 20th and replaced Brigadier General William Heath, they formed a siege line extending from Chelsea, around the peninsulas of Boston and Charlestown, to Roxbury, effectively surrounding Boston on three sides. In the days immediately following, the size of the colonial forces grew, as militias from New Hampshire, Rhode Island, and Connecticut arrived on the scene. The Second Continental Congress adopted these men into the beginnings of the Continental Army. Even now, after open warfare had started, Gage still refused to impose martial law in Boston.

The battle was followed by a war for British political opinion. Within four days of the battle, the Massachusetts Provincial Congress had collected scores of sworn testimonies from militiamen and from British prisoners. When word leaked out a week after the battle that Gage was sending his official description of events to London, the Provincial Congress sent a packet of these detailed depositions, signed by over 100 participants in the events, on a faster ship. The documents were presented to a sympathetic official and printed by the London newspapers two weeks before Gage's report arrived. Gage's official report was too vague on particulars to influence anyone's opinion. George Germain, no friend of the colonists, wrote, "the Bostonians are in the right to make the King's troops the aggressors and claim a victory". Politicians in London tended to blame Gage for the conflict instead of their own policies and instructions. The British troops in Boston variously blamed General Gage and
