But little did the Americans suspect that at the very moment their defence seemed well arranged and their outguards vigilant they were already in the web which the enemy had been silently weaving around them during the night. That flanking column! Skilfully had it played its part in the British plans, and with crushing weight was it now to fall upon our outpost guards, who felt themselves secure along the hills and in the woods. Cross again into the opposite camp and follow the approach of this unlooked-for danger. First, Lord Howe withdrew Cornwallis from Flatbush to Flatlands towards evening on the 26th, and at nine o'clock at night set this flanking corps in motion. Sir Henry Clinton commanded the van, which consisted of the light dragoons and the brigade of light infantry. Cornwallis and the reserve immediately followed; and after him marched the First Brigade and the Seventy-first Regiment, with fourteen pieces of field artillery. These troops formed the advance corps, and were followed at a proper interval by Lord Percy and Howe himself, with the Second, Third, and Fifth brigades, the guards, and ten guns. The Forty-ninth Regiment, with four twelve-pounders, and the baggage with a separate guard, brought up the rear. All told, this column was hardly less than ten thousand strong. With three Flatbush Tories acting as guides, it took up the march and headed, as Howe reports, "across the country through the new lots" towards the Jamaica Pass, moving slowly and cautiously along the road from Flatlands until it reached Shoemaker's Bridge, which crossed a creek emptying into Jamaica Bay, when the column struck over the fields to the Jamaica Road, where it came to a halt in the open lots a short distance south-east of the pass, and directly in front of Howard's Halfway House.[147] [Footnote 147: Consult map of the battle-field, Part II.]
