Fitz John Porter
In 1864, he was promoted to brigadier general. He was the first Judge Advocate General to hold a general's rank. He personally prosecuted the court-martial against Major General Fitz John Porter for crimes of disobedience of a lawful order and misbehavior in front of the enemy. Lincoln also offered Holt the position of Secretary of the Interior that same year and Attorney General later in 1864, but Holt declined both offices.
