After the war, the U.S. government showed its appreciation to Van Lew. “You have sent me the most valuable information received from Richmond during the war,” Grant wrote to her. But left largely unknown to him—and to generations of Americans since— were the scores of people, many of them enslaved, who had risked death to serve as the eyes and ears of the Richmond spy ring.
They included Mary Richards. Now legally free after the war, she left Van Lew’s house to strike out on her own. Since the fall of Richmond, she had been teaching black people there. Later that year, she traveled to New York City to give lectures on her adventures as a Union spy.
Her audiences were spellbound. According to one account, “She urged the educated young men and women to go South” and establish schools to help formerly enslaved people on the “road to freedom.” Even though slavery was over, she said, there was much work to be done to bring justice to black people.
Richards practiced what she preached. In 1867, she ran a school in Georgia for the Freedmen’s Bureau, an agency created by Congress to aid poor Southerners, both black and white, devastated by the war. But faced with a lack of funds and anger from local white people, the school had to close after several months.
