The American general slain was Mercer, whom Washington called "the worthy and brave General Mercer." Early in the conflict his horse was shot under him, and on foot he was attempting to rally his men, when a blow from the butt of a British musket felled him to the ground.
"Call for quarters, you mean rebel!" shouted a British officer.
"I am not a rebel," retorted Mercer; "I am a true soldier of liberty, fighting for his country;" and, as he spoke he thrust his sword at the nearest man.
Then he was bayoneted, and left for dead. He was subsequently borne to the house of a Mr. Clark, where he was nursed until he died, a few days thereafter. Washington supposed that he was killed on the field, until he was on his way to Morristown. On learning that he was still alive, he despatched Major George Lewis with a flag and letter to Cornwallis, requesting that the bearer be allowed to remain with, and nurse, the wounded general. A few days afterwards, Mercer died in the arms of Lewis.
The story spread in the American army that the British bayoneted General Mercer after he gave up his sword. But he said to Major Lewis, who inquired about it: "The tale which you have heard, George, is untrue. My death is owing to myself. I was on foot endeavoring to rally my men, who had given way before the superior discipline of the enemy, when I was brought to the ground by a blow from a musket. At the same moment the enemy discovered my rank, exulted in their having taken the rebel general, as they termed me, and bid me ask for quarters. I felt that I deserved not so opprobrious an epithet, and determined to die, as I had lived, an honored soldier in a just and righteous cause; and without begging my life or making reply, I lunged with my sword at the nearest man. They then bayoneted and left me."
Washington did not pursue the enemy far, nor push on to Brunswick. Most of his troops had been two days and nights without sleep, and they were completely exhausted, so that further engagements without rest were preposterous. He determined to go into winter quarters at Morristown, and marched directly to that place. Stopping at Pluckamin to rest his soldiers for a short time, he wrote to General Putnam:
"The enemy appear to be panic-struck. I am in hopes of driving them out of the Jerseys. Keep a strict watch upon the enemy. A number of horsemen, in the dress of the country, must be kept constantly going backward and forward for this purpose."
Occupying the mountainous region of Morristown, and reinforcing his little army, he harassed the enemy to such an extent that Cornwallis was forced to draw in all his out-posts, so that his land communication with New York was completely cut off.
Hamilton wrote: "The extraordinary spectacle was presented of a powerful army, straitened within narrow limits by the phantom of a military force, and never permitted to transgress those limits with impunity."
