Do you mean March 62? Do you have another account(s) of an undyed wool uniform issue in May? Also only the 1st MO Brigade received those uniforms mainly the 2nd, 3rd, and 5th MO Infantry. The 4th(Formation being finalized in Memphis), and 6th(not formed into "6th" at the time( 2nd Mo inf, MSG, 8th Div and Elliott's Reg, 8th Div, M.S.G.) which were in the 2nd MO Brigade did not get them. Along with 1st MO Inf. being detached.
Mainly when referring to "The Missouri Brigade" it references post Vicksburg. After the 1st and 2nd MO brigades were consolidated into one. Along with the 1st MO being reassigned and consolidated with the 4th after Corinth Oct 62.
Now there are examples of undyed and veg dyed uniforms attributed to members of the 2nd MO Brigade but not the Famous account of the "white wool" uniform issue in March 62 in AR. I am very interested in any more detailed uniform accounts up to the Nov 62-Feb 63 issues while in Holly Springs, and Grenada Miss of "Columbus" depot style uniforms.
