Willis writes from near Frederick City, MD, on the Second Battle of Bull Run or Manassas. His account (which places him at Manassas Junction), describes the battle-scenes and skirmishes, and his belief the "Yankees" had suffered more casualties. He also notes his inability to get some goods at Frederick City on account of the store owners being "Unionists"; his discovery that his hired "boy" was a runaway slave, (he has also fled from Keith); the misery of camp and his idea of resigning and returning to South Carolina to join Marion's Artillery who "will never be sent out of state".
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.
