I like Milroy's account of having a scaffold built for two guerrillas and having set up a public execution without trial at which a thousand people showed up to watch. As the condemned men were standing on the scaffold saying their last words, a dispatch arrives in the nick of time with orders from upon high telling him to cut it out and to give the two men their trial. "This was a great disappointment, especially to my Missouri troops, who are the greatest enemies to bushwhackers I have ever met."

I'm looking for his letter referencing "Guerrillian-Mo. style." What's its date?
