This is a nifty cover sent on November 1, 1864, from Dayton, Ohio, to Colonel Sidney D. Maxwell, Executive Department, Columbus, Ohio! During the early part of the Civil War, Col. Maxwell was a reporter for the Cincinnati Commercial. In 1864, he served as an assistant clerk in the Senate of Ohio and became vitally involved in the organization of the Ohio National Guard. When the Guard was activated in May, 1864, Col. Maxwell went with it as a private. In September 1864, he was assigned as an aide de camp to Governor John Brough of Ohio. After Gov. Brough's death, Col. Maxwell was assigned as an aide de camp to Governor Charles Anderson.

To continue, as for the Scott #65, it's in excellent condition! The cancels from the Dayton P.O. are superb! 

Lastly, as for the envelope, itself, it's in in very good shape for being almost 160 years old. There are some stains on the right side of the front. The back flap of the cover sent is more than 95% intact. The envelope was opened at the right side, and has thus been reduced a bit. Overall, noted imperfections aside, this is still a really neat cover to a Union colonel, and aide de camp to Ohio Governor, John Brough, Sidney Denise Maxwell!
