The choice of Washington for commander-in-chief was suggested and strongly urged by John Adams, and when, on the 15th of June, the nomination was formally made by Thomas Johnson of Maryland, it was unanimously confirmed. Then Washington, rising, said with great earnestness: "Since the Congress desire, I will enter upon the momentous duty, and exert every power I possess in their service and for the support of the glorious cause. But I beg it may be remembered by every gentleman in the room that I this day declare, with the utmost sincerity, I do not think myself equal to the command I am honoured with." He refused to take any pay for his services, but said he would keep an accurate account of his personal expenses, which Congress might reimburse, should it see fit, after the close of the war. [Portrait: Artemas Ward] [Sidenote: Siege of Boston] [Sidenote: Gage's proclamation] [Sidenote: Americans occupy Bunker Hill] While these things were going on at Philadelphia, the army of New England men about Boston was busily pressing, to the best of its limited ability, the siege of that town. The army extended in a great semicircle of sixteen miles,--averaging about a thousand men to the mile,--all the way from Jamaica Plain to Charlestown Neck. The headquarters were at Cambridge, where some of the university buildings were used for barracks, and the chief command had been entrusted to General Artemas Ward, under the direction of the committee of safety. Dr. Warren had succeeded Hancock as president of the provincial congress, which was in session at Watertown.

The only way in which Boston could be made untenable for the British was by seizing and fortifying some of the neighbouring hills which commanded the town, of which the most important were those in Charlestown on the north and in Dorchester on the southeast. To secure these hills was indispensable to Gage, if he was to keep his foothold in Boston; and as soon as Howe, Clinton, and Burgoyne arrived, on the 25th of May, with reinforcements which raised the British force to 10,000 men, a plan was laid for extending the lines so as to cover both Charlestown and Dorchester. Feeling now confident of victory, Gage issued a proclamation on June 12th, offering free pardon to all rebels who should lay down their arms and return to their allegiance, saving only those ring leaders, John Hancock and Samuel Adams, whose crimes had been "too flagitious to be condoned." At the same time, all who should be taken in arms were threatened with the gallows. In reply to this manifesto, the committee of safety, having received intelligence of
