This picture is substantially duplicated on another page, in the Rawdon view, sketched during the continuance of the battle of Bunker Hill. The Mount Pisca (Pisgah) at 19 the present Prospect Hill in Somerville. The lines of Winter Hill and Ploughed Hill would be in the direction of 20. At 27 is a glimpse of the Mystick River seen beyond Charlestown Neck, the armed British transport at 16 commanding the road over that neck. At 22 are the new works of the British, begun after the battle of Bunker Hill, and shown in the contemporary plan of the Charlestown peninsula, given on another page, while the British encampment is on the inner slope of the hill, at 23. Below, and along the shore (24, 24), are indicated the ruins of Charlestown, while the figures 25 mark the position of the redoubt which was defended by Colonel Prescott and his men. The house on the hither shore, below the transport, marks nearly the spot where the present bridge to East Cambridge begins. In the foreground on the extreme right are somewhat vague indications of the dam inclosing the mill-pond, in which the present Haymarket Square occupies a central position.] Perhaps they may have had the grim satisfaction of riding to distant parts of the lines in Thomas Hutchinson's coach, kept now for the general's use, if we may believe the refugee himself.[444] A little later, Josiah Quincy, who from his house at Braintree could look out upon the harbor, had been urging Washington to block the channel, and thus imprison the British ships there at anchor, and prevent the coming of others. Washington appreciated the motives of that ardent patriot, but he would have liked better the cannon and powder that would have rendered the plan feasible.[445] At all events, the possible chances of the plan made not a very pleasant prospect for Howe, who had already set his mind—as, indeed, the ministry had already advised[446]—upon evacuating the town; but his ships were as yet not sufficient for the task, and hardly sufficient to protect his supply-boats from the improvised navy which Washington had been for some time commissioning.[447] John Adams, in Philadelphia, was getting uneasy over the apparent inaction of Washington, and wrote in November (1775) to Mercy Warren that Mrs. Washington was going to Cambridge,[448] and he hoped she might prove to have ambition enough for her husband's glory to give occasion to the Lord to have mercy on the souls of Howe and Burgoyne![449]
