Finally, at one o'clock on the morning of the 18th, he embarked a portion of his forces on flatboats and had them rowed over to Pelham's or Rodman's Point, on the opposite side of Eastchester Pay. They were successfully landed in the darkness. This was a preliminary movement to secure the ground for his main body, which he put in motion at daylight; and simultaneously he caused an embrasure to be opened in his earthwork facing Westchester causeway, so as to give the Americans the impression that he was preparing to force his way over under a cannonade. The Americans readily concluded that such was his object; and strong re-enforcements were speedily sent forward by General Heath, who soon afterward came to the spot in person to direct the operations. Washington himself presently arrived on the scene; and the course taken by him is of much interest in connection with what our readers already know about his strong and persevering suspicion that Howe's design would eventually prove to be a direct advance on Kingsbridge, with the support of a cooperating expedition from the quarter of Morhis "Memoirs," "ordered him risania. Washington, says Heath inhave his division formed ready (Heath) to return immediately and for action, and to take such a position as might appear best calculated to oppose the enemy should they attempt to land another body of troops on Morrisania, which he thought not improbable."

Meanwhile the presence of the British vanguard, which had been ferried ovei in the night, became known to the American force stationed on the neck above, resulting in a series of lively encounters.
