[March 17.] A breast work was discovered, to be thrown up by the Americans at Nook’s Hill on Dorchester peninsula, which from its proximity, had an entire command of Boston Neck and the south end of the town—a work which the king’s troops had most fearfully dreaded. In consequence of it, they began to embark at four o’clock in the morning, and were all on board and under sail before ten.[5] When it was certain that they were quite gone, search was made, for fear of what might be, and fires were discovered in several houses so circumstanced as to intimate a design of setting them on fire, which was happily frustrated. Nothing but prevailing prejudice will impute such design to any other than some unprincipled privates: though an officer of rank was strongly suspected of having plundered under an official character, and of having connived at the rascally conduct of smaller villains. What so hastened the British upon a sight of the works at Nook’s Hill, was probably an apprehension, that the Americans would possess themselves of Noddle’s Island, and by erecting batteries at both places, enclose the harbor with the fire of their cannon. When the king’s troops withdrew from Charlestown, they left centries standing as usual with their firelocks shouldered; but it was soon suspected what regiment they belonged to, and that they were only effigies set there by the flying enemy. It appears by one of the orderly books which was left behind, that their force was 7575, exclusive of the staff; so that with the marines and sailors, Howe might have been considered as 10,000 strong, had it not been for the mutual jealousies which took place between the army and navy. The difficulties which the troops were under, from being so unexpectedly obliged to evacuate Boston, were much increased by the numbers who were under the necessity of removing with them. Many who were disaffected to the American cause had fled there with their families for safety: besides these, there were not a few of the old inhabitants, who concluded it was far more prudent for them to withdraw than remain. Both together, with their families, made up some hundreds, and with their effects encumbered the transports; to which must be added the plunder taken from the town, consisting of furniture and various other articles of a bulky nature. The suddenness of the evacuation prevented an application to Halifax for a supply of shipping to lessen the embarrassments. When the fleet got down to King and Nantasket roads, they remained there several days, and during that period, burnt the blockhouse and barracks on Castle-Island, blowed up and demolished the fortifications; but they did not undertake to carry off the cannon, and only attempted rendering them unserviceable, which was affected as to several.
