On October 5, 1775, General George Washington writes to the president of the Continental Congress, John Hancock, to inform him that a letter from Dr. Benjamin Church, surgeon general of the Continental Army, to Lieutenant General Sir Thomas Gage, British commander in chief for North America, had been intercepted. Washington wrote, “I have now a painful tho’ a Necessary Duty to perform respecting Doctor Church, Director General of the Hospital.”
Washington described how a coded letter to a British officer, Major Crane, came into Washington’s possession by a convoluted route from “a Woman who was kept by Doctor Church.” Washington “immediately secured the Woman, but for a long time she was proof against every threat and perswasion[sic] to discover the Author, however at length she was brought to a confession and named Doctor Church. I then immediately secured him and all his papers.”
