General Powell Clayton

"How come I never heard of this guy?" must be a constant refrain of those of us researching Civil War history -- in this case, mostly using The Encyclopedia of Arkansas History & Culture.

A volunteer from humble origins in Pennsylvania, Clayton did most of his fighting before being promoted to US brigadier general in August 1864. He was a captain at the Battle of Wilson's Creek in Missouri in 1861, but spent most of the war in Arkansas.

Colonel Clayton commanded the right wing cavalry in the successful defense of Helena on July 4, 1863. Then, when Major General Frederick Steele moved from Vicksburg to Helena to command Union forces, Clayton helped him capture Little Rock.

Given independent command at Pine Bluff, on Oct. 25, 1863, he successfully defended it with the assistance of freed slaves against far superior Confederate numbers led by Brigadier General John Marmaduke. The next spring, Clayton led a raid from Pine Bluff in support of Steele's Camden Expedition, itself a part of the Red River Campaign. While the wider campaign was not successful, US forces escaped from disaster, in part due to the positive role of Clayton's force. 

After the war, he was a Reconstruction governor and US senator, then moved with his family to the resort town of Eureka Springs, which he helped develop. Under Presidents McKinley and Teddy Roosevelt, Clayton served as ambassador to Mexico.
