Ron,

Thank you for this information. That would explain why the 3rd Iowa had a cannon at Salem. A gun section was attached to the unit. I can understand why organic artillery would not work well. There is always a battle of priorties over heavy fire assets. Artillery may be severely needed on another part of the field by a field commander in order to win the battle. The battle is then lost because the immediate line commander did not release the artillery because he has them committed for his own purposes.
