C. C. Cox was a Lieutenant in Company E of Waller's Battalion, but apparently left sometime during late 1863 or early 1864 to recruit this company.

"While these later events were going on, I was engaged in raising a second company of cavalry for the war— Walter Mann my neighbor on the Nueces, had obtained from Genl Magruder a commission to raise and organize a Battalion for service in the west—say between the Nueces and the Rio Grande. At his solicitation, I undertook to furnish one of the companies— I had some difficulty in getting released from my company in Wallers Bat—and finally succeeded only through the personal friendship of Genl Green and so with this commission I came out home and went to work to raise the company— Nearly all the available men were already in the service but here and there were men holding back through exemptions of one sort and another—some who had been discharged on account of physical disability and young men not yet of conscript age and some over age— I found John S McCampbell a lawyer, then of Goliad but in late years of Corpus Christi, with about 15 men already recruited—and he joined me in the effort to raise the company— He to be 1st Leut, and I Captain—in a few weeks we had enrolled 60 men and reported at Manns Hd Quarters on the Guadeloupe River— the Bat was organized with 6 companies none of them full (80 men rank &file) but furloughed for a brief time to recruit and fill up the companies—
I had raised this company under a promise to every man of service in the west and I felt under obligations to see that the promise was carried out—and so when we were again ready to go into camp, Col Mann had reported to Genl Bankhead on the Colorado—and the distination of the Regt was changed, by order of Magruder from West to to East—This greatly demoralized the men—Had they been subject to the conscription laws, it would have been different—but these men were volunteers in a double sense and for a special duty—that of protecting our south western frontier—and the interests of that section of country between the Nueces and Rio Grande—and as a considerable force had to be kept in that service—and my men had been recruited for that purpose— it was considered in violation of their contract to divert the command from its original purpose— The up shot of the matter was that the company was disbanded, and nearly all the men returned to their homes— and I proceeded to rejoin my old company—
I think now I made a mistake, and should have submitted to orders and thus preserved my company—but at the time I thought my first duty was to the men that I had persuaded into the services and prefered to sacrifice promotion and honors rather than deceive my men—"
