I thought I would check out the Missouri troop information that has been added to the Soldiers and Sailors system site of the MPS. Why am I not surprised that they got it wrong again. The following is what came up concerning the 8th Missouri Infantry Regiment, CSA. This is the info for, I believe, the 11th.

8th Regiment, Missouri Infantry

8th (Burns') Infantry Regiment, formerly Hunter's 2nd Regiment, was organized in September, 1862. The unit served in General Parson's Brigade, Trans-Mississippi Department, and fought at Cane Hill, Prairie Grove, and Helena where it lost 14 killed, 82 wounded, and 67 missing. On July 6, 1863, it contained 467 effectives and later was redesignated the 11th Missouri Regiment. Its commanders were Colonel Simon P. Burns, Lieutenant Colonel Thomas H. Murray, and Major James Phillips.
