"Black Jack Logan," as he was facetiously called by his soldiers, in consequence of his dark complexion, is the very opposite in appearance and manner of Howard. Logan is a man of Sheridan's short and stumpy style of figure. Sheridan used to be called by the card-playing soldiers the "Jack of Clubs," and Logan was known as the "Jack of Spades." Logan is, too, the same daring, enthusiastic, and vigorous fighter that Sheridan is. He will always be prominent among the Marshal Neys of the war for the Union, and belongs to that representative class of fighting generals of which Sheridan, Hancock, Rousseau, and Hooker are the most distinguished graduates. A man of great daring, and full of dash and vim, Logan was, like the others, great only as a leader, and made no pretensions to generalship. He had the habit of decision to perfection, and went at every thing apparently without previous thought. He is a man who, possessing all that vigor and boldness of heart which great physical strength and health gives, united with a naturally warm, enthusiastic, and daring temperament, engaged heart and soul in every task that allured or interested him, and never abandoned it as a failure. A man of action, he was untiring, and, did he more definitely lay out his plans in life, would win a front place among the great men of the age. Not that he is vacillating, nor yet indecisive, but simply because he is not thoughtful, far-seeing, and politic, but impulsive. He is, indeed, too passionate to ever be politic. With little prudence in planning, Logan had the daring to act, and his decision was shown in frequent emergencies. During the battle of Hope Church, Georgia, the rebels made a sudden charge upon a battery posted in Logan's line, and, before being repulsed, had secured two of the guns, which they attempted to carry off with them. Logan was busy in another part of the field, but, seeing the rebels retiring unpursued with the trophies of their charge, he dashed up to one of the regiments which had repulsed them, and exclaiming to his men, "Bring back those guns, you d--d rascals," led them in a charge for their recovery. The men followed him without regard to formation, and overtook and defeated the rebels before they could reach their lines, and secured the captured artillery. On another occasion, when new to the service, a portion of Logan's regiment mutinied, and, stacking arms, refused to do duty. The adjutant informed Colonel Logan of the difficulty, and he, on hearing it, exclaimed, "Stacked arms! the devil they have!" Then, pausing a second as he considered the emergency, he continued, "Well, adjutant, I'll give them enough of stacking arms!" Accordingly, he formed the remaining four companies in line with loaded muskets, and stood them over the malcontents, whom he compelled to stack and unstack arms for twelve hours.
