The 1st Arkansas Infantry Regiment, Company D (Clan McGregor) is a living history organization based in Pine Bluff, Arkansas. Our membership is composed of a wide variety of people who promote the local history of Jefferson County and that of Arkansas, in general. We principally portray a unit of Confederate infantry serving in the Western Theater of the American Civil War. For historical continuity, we have chosen as our namesake a unit of the Confederate Army of Tennessee known as Company D, 1st Arkansas Volunteer Infantry, and the Clan McGregor of Pine Bluff. In addition to our Confederate impression, we also portray, from time to time, a unit of Federal infantry serving west of the Mississippi River.
