Just 4 days before the armistice on November 11, 1918 at 11AM, Mrs. Hawley, who had learned of the death of her son a couple of weeks prior, received a condolence letter from her sister. Because of the military operations involving U.S. troops in the fall of 1918, this letter was one of many similar pieces of correspondence that were sent to American families that November. After the Second World War, November 11th changed from Armistice Day to Veteran’s Day.
