The message relayed was that the British army had advanced and had forced Washington's troops to retreat to Chadds Ford. The rider found Colonel Alexander Lowry, who was attending worship at Donegal that Sunday, and shared the news with him, to encourage Lowry to organize his men to come to General Washington's defense. Upon learning this news, the congregation gathered around a white oak tree just outside the sanctuary. With hands joined, they vowed allegiance to the cause of the patriots, and their minister, Rev. Colin McFarquhar, who up until that time had always prayed for the King of England, united with them. From that time onward, the tree was known as the “Witness Tree.”The original Witness Tree grew and flourished for nearly three centuries, but succumbed to disease. A cast iron memorial exists in its place now.
