It was one of the rare moments of his life, when the vehement element of his nature was stirred up from its deep recesses. He soon recovered his self-possession, and took measures against the general peril. The enemy might land another force about Hell Gate, seize upon Harlem Heights, the strong central portion of the island, cut off all retreat of the lower divisions, and effectually sever his army. In all haste, therefore, he sent off an express to the forces encamped above, directing them to secure that position immediately; while another express to Putnam, ordered an immediate retreat from the city to those heights. It was indeed a perilous moment. Had the enemy followed up their advantage, and seized upon the heights, before thus occupied; or had they extended themselves across the island, from the place where they had effected a landing, the result might have been most disastrous to the Americans. Fortunately, they contented themselves for the present with sending a strong detachment down the road along the East River, leading to the city, while the main body, British and Hessians, rested on their arms. In the mean time, Putnam, on receiving Washington’s express, called in his pickets and guards, and abandoned the city in all haste, leaving behind him a large quantity of provisions and military stores, and most of the heavy cannon. To avoid the enemy he took the Bloomingdale road, though this exposed him to be raked by the enemy’s ships anchored in the Hudson. It was a forced march, on a sultry day, under a burning sun and amid clouds of dust. His army was encumbered with women and children and all kinds of baggage. Many were overcome by fatigue and thirst, some perished by hastily drinking cold water; but Putnam rode backward and forward, hurrying every one on. Colonel Humphreys, at that time a volunteer in his division, writes: “I had frequent opportunities that day of beholding him, for the purpose of issuing orders and encouraging the troops, flying on his horse covered with foam, wherever his presence was most necessary. Without his extraordinary exertions, the guards must have been inevitably lost, and it is probable the entire corps would have been cut in pieces. “When we were not far from Bloomingdale, an aide-de-camp came to him at full speed, to inform him that a column of British infantry was descending upon our right. Our rear was soon fired upon, and the colonel of our regiment, whose order was just communicated for the front to file off to the left, was killed upon the spot. With no other loss, we joined the army after dark upon the heights of Harlem.”[115]
