Generals Charles Lee and Robert Howe, of the Continental army, hastened immediately to the defense of that city, and among the soldiers who followed them was John Koen. Here again the British were defeated, Colonel Moultrie's Palmetto fortifications proving an effective defense to the city by the sea, and Thompson's South Carolinians and North Carolinians bravely repelling the British land troops. Here Koen fought by the side of the soldiers of North Carolina, and here, possibly, he was an eye witness of the brave deed by which Sergeant Jasper won undying fame.
The British fleet, repulsed in the attempt to capture Charleston, sailed northward, the danger of invasion that for six months threatened the South was over, and we find many of the soldiers in North Carolina released from duty and returning to their homes.
But John Koen's heart was filled with boyish love and admiration for the commander-in-chief of the American army, and his one desire now was to follow Washington; so, shouldering his musket, the hardy young soldier marched away to offer his services to the great general.
We do not know whether or not John Koen was with Washington in the battle at Long Island and at White Plains, but from his own account as related by him to his family, he did have the glorious honor of sharing in the victory at Trenton on December 26, 1776.
Most of us are familiar with the picture of "Washington Crossing the Delaware," wherein he is represented standing erect in a small boat that seems about to be dashed to pieces by the heavy waves and the cakes of ice, but according to Colonel Koen, who was with Washington on that momentous night, no boats were used. The river was frozen over, and the soldiers, in order to keep their footing on the slippery ice, laid their muskets down on the frozen river and walked across on them to the Jersey shore. At times the ice bent so beneath the tread of the men that they momentarily expected to be submerged in the dark waters, but the dangerous crossing was safely made, the British and Hessian troops, spending the holiday hours in feasting and carousing at Trenton, were captured, and a great victory won for the American army.
Some time in the spring of 1777, John Koen must have returned to his home in Pasquotank County, for we find in the Colonial Records that in the month of May, 1777, he enlisted in Moore's Company, Tenth Regiment, from North Carolina, and that in June he was promoted to the rank of corporal.
