The fight was now on in good earnest, and the Spaniards on the hills were engaged in heavy volley firing. The Mauser bullets drove in sheets through the trees and the tall jungle grass, making a peculiar whirring or rustling sound; some of the bullets seemed to pop in the air, so that we thought they were explosive; and, indeed, many of those which were coated with brass did explode, in the sense that the brass coat was ripped off, making a thin plate of hard metal with a jagged edge, which inflicted a ghastly wound. These bullets were shot from a .45-calibre rifle carrying smokeless powder, which was much used by the guerillas and irregular Spanish troops. The Mauser bullets themselves made a small clean hole, with the result that the wound healed in a most astonishing manner. One or two of our men who were shot in the head had the skull blown open, but elsewhere the wounds from the minute steel-coated bullet, with its very high velocity, were certainly nothing like as serious as those made by the old large-calibre, low-power rifle. If a man was shot through the heart, spine, or brain he was, of course, killed instantly; but very few of the wounded died-----even under the appalling conditions which prevailed, owing to the lack of attendance and supplies in the field-hospitals with the army.
While we were lying in reserve we were suffering nearly as much as afterward when we charged. I think that the bulk of the Spanish fire was practically unaimed, or at least not aimed at any particular man, and only occasionally at a particular body of men; but they swept the whole field of battle up to the edge of the river, and man after man in our ranks fell dead or wounded, although I had the troopers scattered out far apart, taking advantage of every scrap of cover.
Devereux was dangerously shot while he lay with his men on the edge of the river. A young West Point cadet, Ernest Haskell, who had taken his holiday with us as an acting second lieutenant, was shot through the stomach. he had shown great coolness and gallantry, which he displayed to an even more marked degree after being wounded, shaking my hand and saying, "all right, Colonel, I'm going to get well. Don't bother about me, and don't let any man come away with me." When I shook hands with him, I thought he would surely die; yet he recovered.
The most serious loss that I and the regiment could have suffered befell just before we charged. Bucky O'Neill was strolling up and down in front of his men, smoking his cigarette, for he was inveterately addicted to the habit. He had a theory that an officer ought never to take cover--a theory which was, of course, wrong, though in a volunteer organization the officers should certainly expose themselves very fully, simply for the effect on the men; our regimental toast on the transport running, "The officers; may the war last until each is killed, wounded, or promoted." As O'Neill moved to and fro, his men begged him to lie down, and one of the sergeants said, "Captain, a bullet is sure to hit you." O'Neill took his cigarette out of his mouth, and blowing out a cloud of smoke laughed and said, "Sergeant, the Spanish bullet isn't made that will kill me." A little later he discussed for a moment with one of the regular officers the direction from which the Spanish fire was coming. As he turned on his heel a bullet struck him in the mouth and came out at the back of his head; so that even before he fell his wild and gallant soul had gone out into the darkness.
