I am trying to determine what Arkansas Infantry Units were involved in the Battle of Pleasant Hill. Sifakis doesnt list Pleasant Hill on most of his list of battles: I think all of the units in Churchills Division were present, so that would be:

Tappan's Brigade
BG James Camp Tappan
19th Arkansas Infantry Regiment (Dawson's)/24th Arkansas Infantry Regiment
27th/38th Arkansas Infantry Regiment
33rd Arkansas Infantry Regiment

Gause's Brigade
Col Lucien C. Gause
26th Arkansas Infantry Regiment
32nd Arkansas Infantry Regiment
36th Arkansas Infantry Regiment

Hawthorn's Brigade[1] 34th Arkansas Infantry Regiment
35th Arkansas Infantry Regiment
37th Arkansas Infantry Regiment
39th Arkansas Infantry Regiment
