Tis funny but a group of us here in Michigan consider ourselves partisan ranges. But its tuff to get event coordinators to accept us as such. They don't like handdguns,or non issued weapons especially any 2 banders. So we call ourselves the 11th Mo. Co. F (confederates).
Gen. Thomas C. Hindman issuded a Confederate Partisan Act in Missouri. satating that when as many as 10 men get together for the purpose they may organize by electing a catain, 1 sergeant and 1 corporal. They will commence operations agaisn the enemy without waiting for special instructions. their duty will be to cut off Federal pickets, scouts, foraging parties and trains. ( sounds alot like Quatrill, and others to me). there is a who list of units that were organised and recognised I have about 2 pages of the units names.
