From the words of General Taylor himself:
Like Mouton, this officer [Gen. Green] had joined me at an early period of my service in western Louisiana. Coming to me with the rank of colonel, his conspicuous services made it my pleasant duty to recommend him for promotion to brigadier and major-general. Upright, modest, and with the simplicity of a child, danger seemed to be his element, and he rejoiced in combat. His men adored him, and would follow wherever he led; but they did not fear him, for, though he scolded at them in action, he was too kind-hearted to punish breaches of discipline. In truth, he had no conception of the value of discipline in war, believing that all must be actuated by his own devotion to duty. His death was a public calamity, and mourned as such by the people of Texas and Louisiana. To me he was a tried and devoted friend, and our friendship was cemented by the fact that, through his Virginia mother, we were related by blood. The great Commonwealth, whose soil contains his remains, will never send forth a bolder warrior, a better citizen, nor a more upright man than Thomas Green.
The brigade of horse brought by General Green to Louisiana, and with which he was so long associated, had some peculiar characteristics. The officers such as Colonels Hardiman, Baylor, Lane, Herbert, McNeill, and others, were bold and enterprising. The men, hardy frontiersmen, excellent riders, and skilled riflemen, were fearless and self-reliant, but discharged their duty as they liked and when they liked. On a march they wandered about at will, as they did about camp, and could be kept together only when a fight was impending. When their arms were injured by service or neglect, they threw them away, expecting to be supplied with others. Yet, with these faults, they were admirable fighters, and in the end I became so much attached to them as to be incapable of punishing them.
