too dangerous.”
    At length the camp was rejoiced by the arrival of Colonel Knox, with his long train of sledges drawn by oxen, bringing more than fifty cannon, mortars, howitzers, beside supplies of lead and flints. The zeal and perseverance which he had displayed in his wintry expedition across frozen lakes and snowy wastes, and the intelligence with which he had fulfilled his instructions, won him the entire confidence of Washington. His conduct in this enterprise was but an earnest of that energy and ability which he displayed throughout the war.
    Further ammunition being received from the royal arsenal at New York, and other quarters, and a reinforcement of ten regiments of militia, Washington no longer met with opposition to his warlike measures. Lechmere Point, which Putnam had fortified, was immediately to be supplied with mortars and heavy cannon, so as to command Boston on the north; and Dorchester Heights, on the south of the town, were forthwith to be taken possession of. Their possession would enable him to push his works to Nook’s Hill, and other points opposite Boston, whence a cannonade and bombardment must drive the enemy from the city.
    The council of Massachusetts, at his request, ordered the militia of the towns contiguous to Dorchester and Roxbury to hold themselves in readiness to repair to the lines at those places with arms, ammunition and accoutrements, on receiving a preconcerted signal.
    Washington felt painfully aware how much depended upon the success of this attempt. There was a cloud of gloom and distrust lowering upon the public mind. Danger threatened on the north and on the south. Montgomery had fallen before the walls of Quebec. The army in Canada was shattered. Tryon and the tories were plotting mischief in New York. Dunmore was harassing the lower part of Virginia, and Clinton and his fleet were prowling along the coast on a secret errand of mischief.
    In the general plan it was concerted that, should the enemy detach a large force to dislodge our men from Dorchester Heights, as had been done in the affair of Bunker’s Hill, an attack upon the opposite side of the town should forthwith be made by General Putnam. For this purpose he was to have four thousand picked men in readiness, in two divisions, under Generals Sullivan and Greene. At a concerted signal from Roxbury, they were to embark in boats near the mouth of Charles River, cross under cover of the fire of three floating batteries, land in two places in Boston, secure its strong posts, force the gates and works at the Neck, and let in the Roxbury troops.
    The evening of Monday, the 4th of March, was fixed upon for the occupation of Dorchester Heights. The ground was frozen too hard to be easily intrenched; fascines, therefore, and gabions, and bundles of screwed hay, were collected during the two preceding nights, with which to form breastworks and redoubts. During these two busy nights the enemy’s batteries were cannonaded and bombarded from opposite points, to occupy their attention, and prevent their noticing these preparations. They replied with spirit, and the incessant roar of artillery thus kept up, covered completely the rumbling of wagons and ordnance.
    As soon as the firing commenced, the detachment under General Thomas set out on its cautious and secret march from the lines of Roxbury and Dorchester. Everything was conducted as regularly and quietly as possible. A covering party of eight hundred men preceded the carts with the intrenching tools; then came General Thomas with the working party, twelve hundred strong, followed by a train of three hundred wagons, laden with fascines, gabions, and hay screwed into bundles of seven or eight hundred weight. A great number of such bundles were ranged in a line along Dorchester Neck on the side next the enemy, to protect the troops, while passing, from being raked by the fire of the enemy. Fortunately, although the moon, as Washington writes, was shining in its full lustre, the flash and roar of cannonry from opposite points, and the bursting of bombshells high in the air, so engaged and diverted the attention of the enemy, that the detachment reached the heights about eight o’clock without being heard or perceived. The covering party then divided; one half proceeded to the point nearest Boston, the other to the one nearest to Castle Williams. The working party commenced to fortify, under the directions of Gridley, the veteran engineer, who had planned the works
