CORNWALLIS DECIDES TO SURRENDER With the failure of the attempt to escape, and the opening of the batteries in the advanced allied line, the position of the British Army, as Cornwallis realized, became hopeless. Our works in the mean time were going to ruin, and not having been able to strengthen them by abbatis, nor in any other manner but by a slight fraizing which the enemy’s artillery were demolishing wherever they fired, my opinion entirely coincided with that of the engineer and principal officers of the army, that they were in many places assailable in the forenoon, and that by the continuance of the same fire for a few hours longer, they would be in such a state as to render it desperate with our numbers to attempt to maintain them. We at that time could not fire a single gun, only one eight-inch and little more than an hundred cohorn shells remained; a diversion by the French ships of war that lay at the mouth of York-river, was to be expected. Our numbers had been diminished by the enemy’s fire, but particularly by sickness, and the strength and spirits of those in the works were much exhausted by the fatigue of constant watching and unremitting duty. Under all these circumstances, I thought it would have been wanton and inhuman to the last degree to sacrifice the lives of this small body of gallant soldiers, who had ever behaved with so much fidelity and courage, by exposing them to an assault, which from the numbers and precautions of the enemy could not fail to succeed. I therefore proposed to capitulate.... EARL CORNWALLIS TO SIR HENRY CLINTON, OCTOBER 20, 1781. 12. THE PARLEY “Mad” Anthony Wayne, brigadier-general of the Pennsylvania Line, has recorded for us the preliminaries of the surrender. _17th._--The enemy beat the chamade at 10 o’clock, A. M.
