Your best bet for finding quick info is to talk with the local county and city historical societies and the county historian's office. They would have the best chance of knowing offhand what happened in the area. They, or the local library, may also have copies of newspapers, etc. that can provide clues.
Barring that, you'll have to research and see what action/campaigns may have occured in the area, determine what units may have been involved, then study the unit histories and any memoirs, etc. that exist.
Good Luck
