Day was breaking and the fog lifting. In the dawning light he shaped his course. No patrol challenged him. Through the rising mist he discerned the outline of the shore and heard the gentle ripple of waves upon the beach. To leave the canoe was like bidding good-by to a faithful friend, but with cartridge-box and musket he stepped ashore and soon found himself upon the spot which he had scanned with the telescope from the Brandon home.

It was plain that he had not miscalculated its value as a military position,—that cannon planted there could plunge their balls upon the great fleet of transports, or upon a vessel attempting to enter or depart from the harbor. He descended the western slope of the hill, reached a narrow path leading across the marsh land, and made his way to Roxbury, to be warmly welcomed by General Nathanael Greene.

“You must tell General Washington about Dorchester Heights. I am going to dine with him to-day, and you must go with me,” said General Greene, who informed Robert that Lieutenant Robert Walden was supposed to have been killed about the same time that Doctor Warren fell.

“But I am here and ready to give an account of myself,” Robert replied.

It was a pleasure to be in the saddle once more,—to ride with General Greene along the works which his troops had constructed. They dismounted at the house of Mr. Vassall in Cambridge, where General Washington had established his headquarters. The commander-in-chief was pleased to welcome him and listen to his story.

Washington’s Headquarters.

“I think, General Washington, that if cannon could be planted there the British fleet could be driven from the harbor. It is a high hill and very commanding. Troops ascending it would do so in the face of a plunging fire from those on the summit. It occurred to me while standing there, that if hogsheads were to be filled with stones and sent rolling upon an assaulting force, it would be an effective means of defense.”
