The brother and sister served with the blue coats for 3 years, Frances reenlisting under various versions of a male personality named Frank every time she was discovered as a female disguised as a man. After her brother was killed she was taken prisoner by the Confederate army and her true identity was discovered. The grey coats were so impressed by her courage that Confederate President Jefferson Davis offered to make her a lieutenant if she joined his army. In true Yankee form, Hook declared she'd rather be a private in the Union Army than a lieutenant for the Rebels. The press found out about the bravery of a young female soldier and interviewed her. Her heroics were written about in periodicals but the Union Army refused to reinstate her. She promised reporters she would head home, but with no home to return to, many speculated that she again reenlisted under a new name.
Later in life she married and had a child, Maggie, who wrote to the War Department after her mother's death seeking confirmation of her mother's military service. The letter was forwarded to the Adjutant General's Office, who was able to confirm Hook's service in the Union Army.
