Boom! It was a broadside from the New York, directed against the battery below El Morro. Instantly every other warship present responded in a deafening crash and a shock to be heard many miles away. At once the air became filled with the smoke, and on shore the dirt and masonry of the batteries were seen to fly in all directions.
"Oh, my!" gasped Walter, as the gun before him belched forth its mass of flame and smoke. "What a noise! Did—did we hit anything?"
"I hope we did," answered Steve Colton, the second gun captain, laconically; and then came the order to unlock the breech of the gun. As the breech fell back a cloud of smoke swirled into the sponson hood, impregnated with the odor of saltpetre, which caused Walter and several of the others to cough violently. "Never mind; you'll get used to it before you die," went on Colton.
The gun being opened, Carl Stuben caught up his hose-pipe, turned on the nozzle and sent a stream of cold water through the gun, to both clean and cool the interior. By the time this was accomplished the hoist had another shell ready, and this was shoved in by the mechanical rammer. Brown prismatic powder followed, with a small quantity of black prismatic powder behind it, as a primer. Then the breech-block was swung into position and locked again, and the electrical connections were adjusted.
All this had been done almost in the time it takes to tell it, but the next shot was not discharged at once, since the various gunners had strict orders to take their time and make every discharge count. It was not like a pitched battle where every moment counted.
But though the gunners took their time, there were so many ships and so many guns that the firing was continuous—a spiteful cracking of rapid-firing guns, mingled with the thunder-claps of the gigantic thirteen-inch guns and the solid banging of the eight-inch and eight and ten pounders.
"This is war and no mistake," remarked Walter. In ten minutes his undershirt had become as black as a stove-cloth, and he himself looked almost like a negro. In the meantime the perspiration was streaming from every pore of his body.
"War!" shouted Caleb. "Why, lad, this is nothing. If only Cervera would come out, then you would see some fun."
The order had been passed to lessen the charges in the big guns and elevate them more, in order to secure a plunging fire. The effect of this change in tactics was soon apparent, as shot and shell began to drop directly into the Spanish strongholds or behind them. Soon one of the batteries was completely silenced, and a cheer went up from the warship nearest to it.
It must not be imagined that the Spaniards took this attack quietly. No sooner had the American warships opened than they returned the fire with equal fierceness. But although at an elevation, and using guns which were stationary, their aim was wild, and only a few of their shots took effect.
