Suddenly, above the cracking of the carbines, rose a peculiar drumming sound, and some of the men cried, "The Spanish machine-guns!" Listening, I made out that it came from the flat ground to the left, and jumped to my feet, smiting my hand on my thigh, and shouting aloud with exultation, "It's the Gatlings, men, our Gatlings!" Lieutenant Parker was bringing his four gatlings into action, and shoving them nearer and nearer the front. Now and then the drumming ceased for a moment; then it would resound again, always closer to San Juan hill, which Parker, like ourselves, was hammering to assist the infantry attack. Our men cheered lustily. We saw much of Parker after that, and there was never a more welcome sound than his Gatlings as they opened. It was the only sound which I ever heard my men cheer in battle. The infantry got nearer and nearer the crest of the hill. At last we could see the Spaniards running from the rifle-pits as the Americans came on in their final rush. Then I stopped my men for fear they should injure their comrades, and called to them to charge the next line of trenches, on the hills in our front, from which we had been undergoing a good deal of punishment. Thinking that the men would all come, I jumped over the wire fence in front of us and started at the double; but, as a matter of fact, the troopers were so excited, what with shooting and being shot, and shouting and cheering, that they did not hear, or did not heed me; and after running about a hundred yards I found I had only five men along with me. Bullets were ripping the grass all around us, and one of the men, Clay Green, was mortally wounded; another, Winslow Clark, a Harvard man, was shot first in the leg and then through the body. He made not the slightest murmur, only asking me to put his water canteen where he could get at it, which I did; he ultimately recovered. There was no use going on with the remaining three men, and I bade them stay where they were while I went back and brought up the rest of the brigade. This was a decidedly cool request, for there was really no possible point in letting them stay there while I went back; but at the moment it seemed perfectly natural to me, and apparently so to them, for they cheerfully nodded, and sat down in the grass, firing back at the line of trenches from which the Spaniards were shooting at them. Meanwhile, I ran back, jumped over the wire fence, and went over the crest of the hill, filled with anger against the troopers, and especially those of my own regiment, for not having accompanied me. They, of course, were quite innocent of wrong-doing; and even while I taunted them bitterly for not having followed me, it was all I could do not to smile at the look of injury and surprise that came over their faces, while they cried out, "We didn't hear you, we didn't see you go, Colonel; lead on now, we'll sure follow you." I wanted the other regiments to come too, so I ran
