Right, note your key word there: Union.
It was a Confederate war of aggression contesting for Union states & territories like:

1. New Mexico
2. Oklahoma
3. Kansas
4. Missouri
5. Kentucky
6. West Virginia
7. Maryland

Together those Union states & territories held nearly 4,000,000 people, enough to almost double the Confederacy's free population.
But they weren't the only states Confederates invaded or had guerilla groups in:

1. California
2. Colorado
3. Indiana
4. Ohio
5. Pennsylvania
6. Vermont

Those states & territories held another 7 million making the total 11 million in Union states threatened by Confederate military forces = 1/2 the Union's population.

Relatively minor incidents, skirmishes & terrorist attacks also happened in:

Maine, New York, Minnesota, Dakota, Arizona & Washington territories.

So you wish to claim: but, but, most battles were fought in the Confederacy!
Sure, overall, but in the war's first 12 months 30 of 52 battles were fought in Union states & territories, it was not until July 1862 that the numbers balanced & shifted to majority in the Confederacy.
