renewed material. Privateers, sent out by him upon the sea, secured
valuable supplies. Henry Knox, a Boston bookseller, whom he had made
colonel of artillery and despatched to New York and Ticonderoga,
returned to the camps with heavy cannon and ammunition.

The right wing of the American army was stationed at Roxbury, under

headquarters of Washington were in the centre, at Cambridge, with
Generals Putnam and Heath. Lee was not allied with the great Virginia

operations, or for commanding a great body of troops.

Meanwhile the British troops, some fifteen thousand veterans, had
remained inactive in Boston, under Sir William Howe, who had succeeded
Gage, unwilling or unable to disperse the militia who surrounded them,
or to prevent the fortification of point after point about the city by

progress had been made thus far in the conquest of New England, for it
was thought unwise to penetrate into the interior with the forces at
command, against the army of Washington with a devoted population to
