I do not have any real knowledge of Civil War artillery and Calvary Organization and equipment during the War, so forgive me if this question might seem ignorant.

My question is "Would Union Calvary Regiments such as the 3rd Iowa Calvary, 5th Illinois Calvary and the 1st Nebraska Calvary, (since they were at times operating independently) have had organic artillery assigned in support, or would artillery would have been loosely attached to them?"

I found reference to Union Artillery piece used by the 3rd Iowa in the report describing the fight at Salem, Arkansas. The other Union Calvary regiments mentioned also operated in the North Central Arkansas area as independent or detached commands. I am researching to see if they also had artillery with or available to them.
