I've been working extensively on the Wikitree Page for the 1st Arkansas Cavalry Regiment of the Union Army. The page can be found here. An ongoing project is identifying the members of this regiment and linking them to the page.

My ancestor Jacob Strickler served in the 1st Arkansas Cavalry of the Union Army.
A book that tells stories of some of the soldiers of the 1st Arkansas Cavalry is a book written in 1862 called Loyalty on the Frontier by Albert Webb Bishop, and it’s a book that gives some insights into what it was like for the Unionist residents of Northwestern Arkansas during the Civil War.
