"As the two men conferred, they were greeted by a familiar sight: American troops in full flight before the enemy. As Knowlton’s men scampered across the Hollow Way, British light infantry followed close on their heels and, wrote Reed, “in the most insulting manner sounded their bugle horns as is usual after a fox chase. I never felt such a sensation before – it seemed to crown our disgrace.”...The light infantry’s ill-advised use of a fox-hunter’s call was clearly an insulting gesture that demanded a response. By nature an inherently aggressive field commander, Washington accommodated and quickly decided to pounce on the redcoats, who had clearly rendered themselves vulnerable by advancing so far beyond their own lines."

"British troops made a tactical error by having their light infantry buglers sound a fox hunting call, “gone away,” while in pursuit. This was intended to insult Washington, himself a keen fox hunter, who learned the sport from his neighbor and mentor near Alexandria, Virginia, the Sixth Lord Fairfax (Thomas Fairfax) during the French and Indian War. “Gone away” means that a fox is in full flight from the hounds on its trail. The Continentals, who were in orderly retreat, were infuriated by this and galvanized to hold their ground."
