In a box filled with stamps, we find a letter from a Civil War soldier to his brother, addressed "Senate Post, Washington, D.C." He asks to command an African American unit. A second letter to the brother in D.C. indicates the soldier has been wounded. Eduardo Pagan sets out to find out why the soldier wanted to lead an African American unit. Did he get his wish?
