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. As for me, though straining every nerve, I could not keep pace with the leaders. My eyes smarted and ached; my head seemed to spin round; more than once I should have fallen but for a friendly hand. Presently I heard Plaza cheer; but he was out of sight, and the sound seemed to come from a long distance. Then I was placed gently against a rock by a soldier, who pushed on after the rest. Had I been hit? I really did not know. There was blood on my hands, but they had been gashed by the jagged rocks. But hit or not, I must do my best to keep up; so trying to steady myself, I took another step forward. The pass was filled with strange sounds and with strange shapes too. Large birds hovered over my head, men and animals stood in my path; I had to dodge here and there in order to find a way through. Suddenly a man placed his arm round my waist, and saying, "You must lie down, lieutenant," carried me a little distance, and then placed me on the ground. "No, no," I murmured drowsily; "the captain is calling! Don't you hear the captain calling?" "Yes," said he: "the Spaniards have escaped, and the captain has sounded a halt." I did not know then that the man was tricking me for my own good, so I answered innocently, "Thank goodness! Now we shall have a little rest. Waken me when they return." "Never fear, sir," said he; "I will waken you," and even before he turned away I had lost all knowledge of the situation. CHAPTER XIII. HOME AGAIN.
