[Feb. 14.] About four in the morning, a party from the castle under col. Leslie joined another, amounting to about five hundred, sent over the ice to Dorchester Neck by gen. Howe. They burnt about half a dozen houses; but the general’s scheme failed. He had been up the whole night, getting ready for an attack with a large body of troops. He expected, that the burning of the houses would occasion such an alarm, as to put the American officers upon sending from Roxbury lines a large reinforcement, and thereby giving him an advantageous opportunity of attacking them; but at day break, he found their men as usual at their alarm posts, so that he declined it. The strength of the ice having been tried in one place, and the frost continuing, general Washington was desirous of embracing the season for passing over it, from Cambridge side into Boston. He laid before a council of war [Feb. 16.] the following question: “A stroke well aimed at this critical juncture, may put a final period to the war, and restore peace and tranquility so much to be wished for, and therefore whether, part of Cambridge and Roxbury bays being frozen over, a general assault should not be made on Boston?” General Ward opposed the idea, saying, “The attack must be made with a view of bringing on an engagement, or of driving the enemy out of Boston, and either end will be answered much better by possessing Dorchester heights.” General Gates was also against it. The commander in chief was evidently for it. He did not appear enough sensible of the importance of Dorchester heights; and probably confided too much in the courage and perseverance of the continental troops and militia. When the votes were called for, the majority were against the attack. The commander in chief could not refrain from showing that he was greatly dissatisfied. But a negative being put on the question, the next point to be considered was, whether they should possess themselves of Dorchester heights, with a view of drawing the enemy out. This was agreed upon; and the conducting of the business was left wholly to general Ward, who with generals Thomas and Spencer, commanded on that quarter. They had been for some time collecting fascines, gabions, &c. unknown to general Washington, in expectation that the same would be wanted for this purpose. Had they not practised such foresight, it is to be much doubted whether they could have been in sufficient forwardness. The militia, which were called for from the New-England colonies to assist in some grand operation meant to be undertaken between the first of February and the end of March, collected apace; but the want of arms was prodigious. Every thing was carried on with the utmost expedition; that so the heights might be occupied as soon as possible. The design was no secret, and many were fearful, that general Howe would secure them before the Americans—but he could not spare a sufficient force for the purpose.
