When Washington found that the enemy had made their principal landing at Thirty-fourth Street, and that a retreat was necessary, he sent back word to have Harlem Heights well secured by the troops there, while at the same time a considerable force under Mifflin marched down to the strong ground near McGowan's to cover the escape of troops that might take the King's Bridge road. Chester and Sargent evacuated Horn's Hook and came in with Mifflin. Upon the landing of more troops at Kip's Bay, Howe sent a column towards McGowan's, and in the evening the Light Infantry reached Apthorpe's just after Silliman's retreat. Washington had waited on the Bloomingdale Road until the last, and retired from the Apthorpe Mansion but a short time before the British occupied it. Here at Bloomingdale the enemy encamped their left wing for the night, while their right occupied Horn's Hook, their outposts not being advanced on the left beyond One Hundredth Street. The Americans slept on Harlem Heights, not quite a mile and a half above them. "That night," says Humphreys, "our soldiers, excessively fatigued by the sultry march of the day, their clothes wet by a severe shower of rain that succeeded towards the evening, their blood chilled by the cold wind that produced a sudden change in the temperature of the air, and their hearts sunk within them by the loss of baggage, artillery, and works, in which they had been taught to put great confidence, lay upon their arms, covered only by the clouds of an uncomfortable sky."[192] [Footnote 192: The American loss in prisoners in the Kip's Bay affair was seventeen officers and about three hundred and fifty men, nearly all from Connecticut and New York. A very few were killed and wounded, Major Chapman, of Tyler's regiment, being among the former. The officer of highest rank among the prisoners was Colonel Samuel Selden, of Hadlyme, Conn., mentioned on page 121. (See biographical sketches, Part II.) One of his officers was Captain Eliphalet Holmes, afterwards of the Continental line, a neighbor of the Colonel's. Being a man of great strength he knocked down two Hessians, who attempted to capture him, and escaped.]
