(AP) — More than 30 Kansans are going to Georgia this month to recreate a 150-year-old Civil War battle.

Besides re-enacting the Battle of Chickamauga, the soldiers will hold a memorial service to honor the spot where the 8th Kansas Volunteer Regiment experienced its worst moment.

The  regiment was organized in 1861, months after the start of the Civil War. It was to be a Home Guard Unit but was soon called elsewhere.

Kansas historian and filmmaker Ken Spurgeon says the unit was the state’s busiest and lost 54 percent of its men and four flag bearers at Chickamauga. He says their graves need to be visited, marked and memorialized.
