Definitely going to have to give that a read.
I actually had the idea for a PhD dissertation once upon a time: "To Execute the Laws of the Union: Domestic Employment of the Federal Military, 1789-present." I would have excluded the Indian wars and the Civil War, but the draft riots would probably have qualified for inclusion. The idea came from reviewing the Color series of war plans. There was one (either White or Blue, I forget) that was for domestic insurrection/rebellion.
I'm pretty sure my regiment - 6th Infantry - was one of the units sent to NYC to put down the riots. I know that Gettysburg is the regiment's last Civil War campaign streamer, because there simply wasn't much left of the regiment after that.
