By the time I had come to the head of the regiment we ran into the left wing of the Ninth Regulars, and some of the First Regulars, who were lying down; that is, the troopers were lying down, while the officers were walking to and fro. The officers of the white and colored regiments alike took the greatest pride in seeing that the men more than did their duty; and the mortality among them was great. I spoke to the captain in command of the rear platoons, saying that I had been ordered to support the regulars in the attack upon the hills, and that in my judgment we could not take these hills by firing at them, and that we must rush them. He answered that his orders were to keep his men lying where they were, and that he could not charge without orders. I asked where the Colonel was, and as he was not in sight, said, "Then I am the ranking officer here and I give the order to charge"--for I did not want to keep the men longer in the open suffering under a fire which they could not effectively return. Naturally the captain hesitated to obey this order when no word had been received from his own Colonel. So I said, "Then let my men through, sir," and rode on through the lines, followed by the grinning Rough Riders, whose attention had been completely taken off the Spanish bullets, partly by my dialogue with the regulars, and partly by the language I had been using to themselves as I got the lines forward, for I had been joking with some and swearing at others, as the exigencies of the case seemed to demand. When we started to go through, however, it proved too much for the regulars, and they jumped up and came along, their officers and troops mingling with mine, all being delighted at the chance. When I got to where the head of the left wing of the Ninth was lying, through the courtesy of Lieutenant Hartwick, two of whose colored troopers threw down the fence, I was enabled to get back into the lane, at the same time waving my hat, and giving the order to charge the hill on our right front. Out of my sight, over on the right, Captains McBlain and Taylor, of the Ninth, made up their minds independently to charge at just about this time; and at almost the same moment Colonels Carroll and Hamilton, who were off, I believe, to my left, where we could see neither them nor their men, gave the order to advance. But of all this I knew nothing at the time. The whole line, tired of waiting, and eager to close with the enemy, was straining to go forward; and it seems that different parts slipped the leash at almost the same moment. The First Cavalry came up the hill just behind, and partly mixed with my regiment and the Ninth. As already said, portions of the Third, Sixth, and Tenth followed, while the rest of the members of these three regiments kept more in touch with the infantry on our left.
