I believe he did, based on a letter he wrote to his son in January 1861. However he made the decision to go with his state and he never wavered. You have to respect him for that.
Ironic that a man who hated war probably extended the Civil War for years because of his military genius and capacity for leadership. If he had accepted Lincoln’s offer to command the Union forces the war would have been over the first year.
Do you have a link for that letter somewhere? I’d be interested in reading it.
