It was during this memorable winter at Valley Forge that a man by the name of Potts was strolling through the woods, when he heard the sound of a human voice. Cautiously approaching the spot whence the voice proceeded, what was his surprise to discover Washington on his knees engaged in earnest prayer for his country. On returning home, Potts called to his wife, "Sarah, Sarah, all is well. George Washington will triumph!" "What is the matter now, Isaac? Thee seems moved," Mrs. Potts replied. (They were Quakers.) "I have this day seen what I never expected to see," Mr. Potts continued. "Thee knows that I have always thought the sword and the gospel utterly inconsistent, and that no man could be a soldier and a Christian at the same time. But George Washington has this day convinced me of my mistake." He then described the scene he had witnessed, adding: "If George Washington be not a man of God, I am greatly deceived; and still more shall I be deceived if God does not, through him, work out a great salvation for America." Baron Steuben, a renowned European general, coming to this country at this juncture to proffer his services, through the influence of Dr. Franklin, Washington induced Congress to commit the reorganization of the army to him. This proved a fortunate arrangement for the future of the army and country, next to the appointment of General Green quarter-master-general. Previously a distinguished Pole, Thaddeus Kosciusko, who was educated in the military school at Warsaw, had come to him with a letter from Dr. Franklin. "And what do you seek here?" inquired Washington. "To fight for American independence," replied Kosciusko. "What can you do?" "Try me." Washington welcomed him heartily, and throughout the Revolution he proved to be an able and faithful ally. Count Pulaski, another famous general of Poland, had joined the American army at the solicitation of Dr. Franklin, who introduced him by letter to Washington. Washington had corresponded with the British general respecting an exchange of General Lee and Ethan Allen, but he was unable to effect an exchange until this winter of his trials at Valley Forge. General Prescott, who captured Allen in Canada, ironed him, and sent him to England, was himself captured in the summer of 1777; and Washington proposed to exchange him for General Lee, and Colonel Campbell for Colonel Allen. It was not, however, until near the close of the long dreary winter at Valley Forge that his proposition was accepted. Lee rejoined the army, but Allen returned to his home in Vermont, where he hung up his sword and retired to private life.
