At daybreak the next morning the Spaniards attacked our troops, and the fighting went on all day. A sharp attack was made in the evening, but our men still held the place. Yet they did not feel secure. The Spanish Army in Santiago was a large one, and might force our men back. Our men, though weary from marching and fighting and digging, hungry, for food was scarce, wanted to hold the heights that had been so dearly won. The attack upon the Spanish defenses of Santiago began early in the morning of July 1st, as I have told you, and I wish I could tell you the one hundredth part of the brave and gallant deeds that were done by our brave soldiers on that and the next day. [Illustration: Lieutenant John H. Parker.] Battery A, of the Second United States Artillery, fired the first shot of the engagement known as the battle of El Caney. The Spaniards replied, after it had sent five shells among them. The Spanish forces were much stronger than our men thought they were, and it took General Lawton nearly all day to gain possession of El Caney. Early in the day, Lieutenant Parker's battery of four Gatling guns began to hurl bullets into the Spanish trenches, and so well did it keep up the work that it played a very important part in the battle and a great deal of the credit of the victory is due to Lieutenant Parker. Afterwards, Lieutenant Parker, in speaking of these wonderful machine guns, said: "We trained the guns on the top of the hill. They were fired above the heads of the slowly advancing line of blue which had started up the slope. I ordered the men to work the Gatlings as fast as they could. The result was astounding. With each of the four guns firing at the rate of eight hundred shots a minute, the bullets formed a canopy over the heads of the men at the foot of the hill. A Gatling gun in action is a sight to remember; so thick and fast do the bullets fly that one can actually see the stream of lead leaving the gun and, as if handling a hose, train it on any desired point. "I remember one incident of the first day which showed how deadly was the fire of these machine guns. Away off, across the valley, we saw a clump of Spanish cavalrymen. I ordered the guns turned on them. They were so far away we had to use glasses to find them accurately, but when the little wheels began to turn, those who stood in the front line of the clump fell as grass falls before a mower, and it didn't take the rest of those Spaniards long to get behind something. "As the day wore on, and the troops kept climbing up the hill, Colonel Roosevelt, who had been watching the work of the Gatlings, came along and placed his light battery of two Colt machine guns and one dynamite gun in my command." You can get an idea of the deadly work of the Gatlings when I tell you that the fire of one of these guns is equal to that of one hundred and eighty riflemen, each discharging thirteen shots per minute.
