"No, no," he roared; "I take no advantage!" and he ran on, holding by the stirrup to the nearest horseman.

The fellows cheered him, and I think we got on better for the incident, though the halts became more frequent now, and our numbers lessened, as one man after another dropped exhausted to the ground. Still we were gaining on the runaways, as a disagreeable episode presently made clear.

It was about four o'clock in the afternoon, and we were straggling at no great speed through a narrow valley, when half a dozen bullets from the rocky sides dropped into our midst.

"Ah!" exclaimed Castro, "now the Spaniards are playing the proper game. These fellows have been left to hold us in check while the main body escapes through the Copari Pass."

"Push on there!" roared the captain, who after a spell of riding had just dismounted. There was, indeed, nothing else to be done. We must run the gauntlet, and trust to luck for some of us getting through. The Spaniards were well hidden, and could not be dislodged, unless, which was out of the question, we came to hand-grasps with them. So urging our jaded beasts to a spurt, we quickened the pace, while now and again a groan and a thud told that a bullet had found its mark.

Those who were hit lay where they fell; the most of us reached the open country just in time to see a dozen or fifteen horsemen mount and ride off. Evidently they had the pick of Santalla's animals, as they easily kept their distance, though allowing us to advance within range, when, discharging their muskets, they recommenced the retreat.

Plaza fumed like one distracted at the galling fire, which considerably delayed our advance, though we suffered in the loss of horses rather than of men. He was riding again now, and well in front, with Castro and myself behind him. Suddenly, after a scattering volley, I felt my horse slip, and the next instant the poor beast was sprawling on the ground with a bullet-hole in its chest.

Staggering to my feet, I ran on, but unsteadily, for in truth I was getting very near the end of my strength. However, a husky shout from those in front encouraged me, and I saw that at last we had come fairly upon the runaways.

Just as Castro had foretold, they were taking to a mountain pass, eastward of Copari, and the main body was already toiling up the ascent. Their stores lay about everywhere; horses and mules were abandoned; only a handful of horsemen, constituting the rearguard, preserved any appearance of order. For a time they stoutly held the mouth of the pass, but at length, leaving their animals, they too disappeared.

Plaza went at the entrance like a bull at a gate, Castro followed, and I toiled after them with the men. Up we went, some cheering, but the majority with closed lips, saving their breath. In our fatigued state the climb was fearfully distressing: men sank to the ground gasping, or fell while trying to grasp the overhanging rocks with nerveless fingers.
