As we gazed across again at the Old Manse we thought of the wonderful essays that had been written here. In the rear of the old house is a delightful study. It was here that Emerson wrote "Nature." Here, too, Hawthorne wrote "Mosses from an Old Manse." We thought of the brave clergyman who, from the north window, commanding a broad view of the river, stood watching the first conflict of a long and deadly struggle between the mother country and her child. Realizing the danger they were in, the British troops began their retreat of eighteen miles. They had eaten little or nothing for fourteen hours. Ages ago freedom loving Nature had conspired to aid the Americans by shaping the field of battle. Huge boulders had been left by the glacier, the potent rays of the April sun made dense masses of verdure in willows, which thus became an ally of the pine. Stone fences and haystacks became ready-made fortifications, and every rising spot was filled with irate hostile yeoman who harried them with aim true and deadly. They soon began to run and leave their wounded behind, and in place of a retreat their disorderly flight must have had the appearance of a Marathon race, the rattle of musketry acting or serving as signals for each to do his best on the home stretch. They were almost exhausted when they fell into a little hollow square made by Percy's men to receive them. Here the weary, frightened Redcoats took refuge as in a sanctuary, and immediately threw themselves upon the ground to rest. Many of them had either lost or thrown away their muskets. Pitcairn had lost both his horse and the elegant pistols with which. the first shot of the war for independence had been fired. They may now be seen in the town library of Lexington. When the British soldiers reached Arlington, several miles from Boston, they had an obstinate fight with the Yanks. The road swarmed with Minute Men and they could not keep order--but at sunset, when they entered Charlestown under the welcome shelter of the fleet, it was upon the full run. Considered as a race, the British stood far in the lead. Two hundred and seventy-three British were lost and but ninety-three Americans.
