Immediately our guns opened, and at the report great clouds of white smoke hung on the ridge crest. For a minute or two there was no response. Wood and I were sitting together, and Wood remarked to me that he wished our brigade could be moved somewhere else, for we were directly in line of any return fire aimed by the Spaniards at the battery. Hardly had he spoken when there was a peculiar whistling, singing sound in the air, and immediately afterward the noise of something exploding over our heads. It was shrapnel from the Spanish batteries. We sprung to our feet and leaped on our horses. Immediately afterward a second shot came which burst directly above us; and then a third. From the second shell one of the shrapnel bullets dropped on my wrist, hardly breaking the skin, but raising a bump about as big as a hickory-nut. The same shell wounded four of my regiment, one of them being Mason Mitchell, and two or three of the regulars were also hit, one losing his leg by a great fragment of shell. Another shell exploded right in the middle of the Cubans, killing and wounding a good many, while the remainder scattered like guinea-hens. Wood's lead horse was also shot through the lungs. I at once hustled my regiment over the crest of the hill into the thick underbrush, where I had no little difficulty in getting them together again into column. Meanwhile the firing continued for fifteen or twenty minutes, until it gradually died away. As the Spaniards used smokeless powder, their artillery had an enormous advantage over ours, and, moreover, we did not have the best type of modern guns, our fire being slow. As soon as the firing ceased, Wood formed his brigade, with my regiment in front, and gave me orders to follow behind the First Brigade, which was just moving off the ground. In column of fours we marched down the trail toward the ford of the San Juan River. We passed two or three regiments of infantry, and were several times halted before we came to the ford. The First Brigade, which was under Colonel Carroll--Lieutenant-Colonel Hamilton commanding the Ninth Regiment, Major Wessels the Third, and Captain Kerr the Sixth--had already crossed and was marching to the right, parallel to, but a little distance from, the river. The Spaniards in the trenches and block-houses on top of the hills in front were already firing at the brigade in desultory fashion. The extreme advance of the Ninth Cavalry was under Lieutenants McNamee and Hartwick. They were joined by General Hawkins, with his staff, who was looking over the ground and deciding on the route he should take his infantry brigade.
