what were the 3 major areas if the combat in the civil war? PLEASE HELP!!?

Answer 1

Eastern theatre pitting the Army of the Potomic against the Army of Northern Virginia.

The Western Theatre centering along the Mississippi River, most notably Vicksburg.

I suppose the 3rd major area was around Murfreesboro, Chattanooga and Chicamauga.

The real action was in the east.
