But there is a limit to what courage can do, and the unfortunate sailors soon learned it. They came to a second clearing, a broad savanna this time. "We'll have to run for our very lives," gasped Clif. For if they failed to reach shelter before the Spaniards came up the former situation would be just reversed and the Spaniards could hide and fire in safety. And so the men set out at breakneck speed, as if they were in a hundred yard's dash. "I think we can make it," thought Clif. "They seem to be a long ways behind." The shouts of the enemy indicated it; Clif's volley had seemed to deprive them of their former confidence and rashness. But unfortunately, they were not the only Spaniards in Cuba. The firing had not failed to attract attention. The Americans had reached about the centre of the broad plain. There was high grass and cane upon it, and that made even walking hard. But the men still plunged on bravely, though they were gasping for breath. But then something happened that made them gasp still more. For the shouts of the enemy in the rear were suddenly answered. And the answer came from in front. The sailors halted and stared at each other in consternation. "Do you see anything?" cried Clif. All that could be made out was a line of bushes and undergrowth, marking the beginning of the woods. But out of it came a confused babel of shouts, as if a whole army were there and had been suddenly alarmed. "They'll head us off!" gasped the sailor. But they stood still for only a second; now was no time to delay. The pursuers in the rear were drawing closer every instant. There was only one thing left. They were shut off in two directions, but off to each side---- "Come!" gasped Clif. And the sailors whirled about and followed him in the new direction. It was a hopeless hope, but it was not yet time to give up. And so for perhaps a hundred yards they raced on. They had heard a shout behind them, and saw the Spaniards running out from the woods, both in front and behind. "Turn and fight them!" shouted Clif. Like wild animals at bay the sailors faced about and jerked out their revolvers again. They were on the point of opening fire, when suddenly, as if they were not in trouble enough, there came a new development. There was a yell behind them, and a crashing sound. Out upon the broad savanna galloped a whole troop of Spanish cavalry, their carbines in their hands. And at their head rode a brightly uniformed captain waving his sword and galloping down upon the fugitives. "Surrender!" he yelled. "Lay down your arms." And that was the last straw; the sailors looked at Clif, and Clif looked at the sailors. The troopers were not a hundred yards away, and there were fifty of them. "I guess we may as well give up," said Clif, grimly. "We've done our best, I think." And he turned toward the galloping men, dropped his sword and revolver, and then folded his arms. "We surrender," he called. "Come on."
