During the winter the division of the Fourth Corps commanded by Brigadier-General Thomas J. Wood had been in closest connection with us. It had taken part in all the marchings and countermarchings of the period when I was chief of staff, and I had thus begun an acquaintance with its commander which was to grow into lasting friendship. General Wood was colonel of the Second Regular Cavalry, a Kentuckian who had earnestly taken the National side, and an influential officer of the old army. His intelligence and activity were very marked, and his courage was of the cool indomitable character most highly prized in divisions of a great army. Of medium height, solid but not large build, dark hair and complexion, high forehead, he was a noticeable man in any assemblage of officers. A fluent talker, attentive to polite forms of speech as well as of conduct, he was liked and respected throughout the army, and especially in the Army of the Cumberland, where he had served throughout the war. He had won promotion by gallant and meritorious services again and again, when at the battle of Chickamauga it was his ill fortune to receive the famous order to "close up on Brannan and support him." The situation made the order ambiguous, but Wood understood it to mean that he should move to the left till he should find himself in rear of Brannan's division, since another division was between them in the line. He thought it a strange order, but thought also that Rosecrans must know why he sent it, and that it was "his not to reason why" but to obey. The obedience opened the gap through which Longstreet's men poured, breaking the line and routing part of the right wing. Wood took the place assigned him by Thomas in the horse-shoe curve around the Snodgrass hill, and did his full share of the desperate fighting which held that part of the field. But he had thus become the subject of a controversy, and the friends of Rosecrans charged him with a too literal obedience, and a failure to use a sound discretion in his action. The result was that whilst Rosecrans was removed from active field service, Wood still found himself under a cloud, and opposed by influences which stood in the way of his promotion till the war was almost ended. He continued to be distinguished in every engagement of the Atlanta campaign and that of Nashville, and no division saw harder or more honorable service than his.
