Let us now return to the King's soldiers under the command of Lieut.-Col. Smith, whom we left on the shore of Charles River at Lechmere Point in Cambridge. It was one o'clock on the morning of the 19th, before the column was fully under way.[91]

Lechmere Point then had but one house, which stood on the southern slope of the hill, on the northern side of Spring Street, between Third and Fourth Streets, and facing to the south.[92] Where the troops landed, on Second Street, was sufficiently remote to be out of sight and hearing, evidently the particular aim of the commanding officer.

They proceeded cautiously, following an old farm-road around the northeasterly slope of the hill, sometimes wading in the marshes that bordered Willis Creek, and fording that stream, waist-deep, in the vicinity of Bullard's Bridge.

Smith evidently thought that the noise of his soldiers tramping across the bridge itself might attract attention. His soldiers found the ford a long one, and the waters deep.[93]

Even thus early on the expedition was the British Army betrayed by one of its own soldiers, if the tradition handed down by a Mrs. Moore can be relied upon. Seventy-five years or more ago she related to Rev. J. L. Sibley, who has stated accordingly, that she was then living in Cambridge, a young girl, and that one of the soldiers was taken sick after his landing at Lechmere Point, and accordingly permitted by his commander to return by boat to Boston. He did not immediately return, however, but made his way to the solitary farm-house where Mrs. Moore was living. The occupants gained from him the significance of his midnight presence, and it was considered of sufficient importance to communicate speedily to their fellow townsmen.

Bullard's Bridge crossed Willis Creek, near the present Prospect Street, which runs from Cambridge to Somerville.[94] Later on the Creek was called Miller's River. It was then a little tributary to the Charles River, but has long since been filled in, and modest dwellings, and more pretentious business establishments now cover its upper area.
