Nor was he surprised to behold Shepard now. He merely wondered that he had not seen him earlier, so great was his activity and daring, and he had no doubt that he had brought the gunboats and the Union troops warning that Stuart was coming. He was sure of it the moment the cavalry emerged from the woods, because one of the gunboats instantly turned loose with two heavy guns which sent shells whistling and screaming over their heads. Had they been a little better aimed they would have done much destruction, and Harry saw at once that they were going to have an ugly time with these saucy little demons of the water. Another boat fired. One of the cavalrymen was killed and several wounded. Stuart promptly drew his men back to the edge of the wood, unlimbered and posted his cannon. Quick as they were, the black wasps on the river buzzed and stung as fast. Shells and solid shot were whistling among them and about them. They were good gunners on those boats and the men in gray acknowledged it by the rapidity with which they took to shelter. But Stuart's blood was at its utmost heat. He had no intention of being driven off, and soon his own light guns were sending shell and solid shot toward the boats, which had relanded their troops on the other side, and which were now puffing up and down the river like the angry little demons they were, sending shells, solid shot, grape and canister into the woods and along the slopes where the horsemen had disappeared. Harry and Dalton were glad to dismount and to get behind both the trees and the curve of the embankment. Harry, despite a pretty full experience now, could not repress involuntary shivers as the deadly steel flew by. He and Dalton had nothing to do but hold their horses and watch the combat, which they did with the keenest interest. Stuart's cannon had unlimbered in a good place, where they were protected partly by a ridge, and their deep booming note soon showed the gunboats that they had an enemy worthy of their fire. Dalton and Harry looked on with growing excitement. Dalton, for once, grew garrulous, talking in an excited monotone. "Look at that, Harry!" he cried. "See the water spurt right by the bow of that boat! A shell broke there! And there goes another! That struck, too! See the fallen men on the boat! Look at that little black fellow coming right out in the middle of the stream! And it got home, too, with that shot! By George, how the shell raked our ranks! Ah, but, you saucy little creature, that shell paid you back! See, Harry, its wheel is smashed, and it's floating away with the stream! Guns on land have an advantage over guns on the water! As the negro said, 'When the boat blows up, whar are you? But if the explosion is on dry land, dar you are!' Ah, another has caught it, and is going out of action! Oh my, little boats, you're brave and saucy, but you can't stand up to Stuart's guns."
