Dear Bernard
In further to the post 6th August on Starbuck, there is the option of Starbuck heading to Mexico with Jo Shelby who refused to surrender. Shelby himself was called by a Union Cavalry General (who had fought in the East too) as the best he ever saw.
I do wonder if you would ever get Starbuck to the Western Theatre anyway as it’s relatively unexplored. While Starbuck should at least meet Patrick Cleburne dubbed the Stonewall in the West at least once.
Yours sincerely
P.S If you have not read it, I would recommend A World on Fire by Amanda Foreman on the British presence and people who fought in the US Civil War. Very interesting.
