"Albet Pike resigned on July 12,1862 at Fort McCulloch,I.T."

Yes, this was the results of the feud between he and Hindman. Each accusing the other of different things. T. H. "Granny" Holmes relieved Hindman as commander of the Department of Arkansas not long after Pikes resignation. This argument between Hindman and Pike may well have been one of the reason for the demotion of Hindman.

All I can say is that Hindman had his back against a wall trying to build an army from nothing that was capable of bluffing Curtis into turning away from marching into Little Rock in the summer of 1862. Pike nor Texas was threaten at Fort McCullock at the time. Nor, as you point out, never was during the entire war. Hindman did not have arms or ammunition enough to equip one regiment, and Pike had plenty at Fort McCullock. Hindman send details to Fort McCullock to get some of this equipment for his needs several times and was rebuffed by Pike at every turn.
