Sorry, my great grandfather Peyton Green Whaley saw action with Monroe's Cavalry at the battles of Cane Hill and Prairie Grove Arkansas, not "Pleasant" Grove.
He wrote a good account of those battles from his perspective.
Pvt. Whaley enlisted in Monroes' Cavalry on May 22, 1862 at Washington, Arkansas. He was an overseer on the John Anderson Plantation and lived on the plantation at Bois d' Arc Arkansas.
