Willis writes from Charlestown, Va, on having taken 1,300 prisoners at Harpers Ferry (many Vermonters); on the Second Battle of Bull Run or Manassas; his continued interest in resigning and joining Marion Artillery in South Carolina; the deaths of Nathaniel Heyward and Lt. Munroe of Charleston and his frustration at not being able to secure a slave to tend to him. He notes that he is writing on "captured paper" and the pro-Union sentiment on the envelope ("The Union and the Constitution must and shall be preserved") is crossed out.
