You speak of the problems with Jackson. During this time the guys in the Army of the Northwest felt themselves ill-used by Jackson and that he was prejudiced in favor of his Stonewall Brigade. The men of the Northwestern Army felt loyalty to their original commander Gen. William Wing Loring. Although Loring was a no nonsense commander he had the welfare of his men at heart. The troops of Loring's command felt this was not so of Jackson. To get a glimpse of this, read Thomas Rankin's 37th Virginia of the Virginia Regimental History Series. After the romney Campaign Jackson moved his Stonewall Brigade to the relative comfort of winchester and left the troops of Loring to fend for themselves in a harsh environment with no consideration. Taliferro's Brigade, of which the 3rd Arkansas was a part, called the Stonewall
Brigade "Jackson's Pet Lambs". I have read letters from members of the 37th Virginia and have been told stories by my grandfather of tales related to him by his uncle who served in the 37th Va. In these stories my great-great uncle had things to say about Jackson that were not flattering. Not do the letters I have read have anything good to say. So it is probably quite true that Jackson discriminated against the 3rd Arkansas.
