The red jackets of the Dragoons--the few that were left--brightly dotted the van of the attacking thousands. On either side rode the Second and Fourth Lanciers. Behind tramped the battalions of Iturbide, of Celaya, and regiments of the line. They gained the foot of the hill and the cavalry were dismounting before they drew fire. The baptism had a sharpshooter deadliness, even at that distance, but the Imperialists waited tentatively. No, there was but one volley. When the second came, it was only after an interval long enough for reloading. Officers and men glanced at one another more hopefully. The terrified fugitives were of course mistaken, they thought. For the force above could not be large, nor yet possess the mysterious sixteen-shot rifles. The assurance gave the buoyancy of relief. To charge against carbines that made each man as sixteen were uncanny, too much like challenging the Unknown. But a thousand men who fired only every two or three minutes--an antagonist like that was quite well known to their philosophy. So breathing hard, they valiantly marched up the hill. They suffered cruelly under the scattered fusillades, yet were not materially resisted. At last they were near enough, and the bugles sounded for the final rush. Now what was odd, the Republicans stopped firing altogether. But they were waiting for shorter range, and a moment later, at a hundred paces, their reopening volley had all the clockwork dispatch of platoon drill. Yet the Imperialists took the dose as a thing expected, and sprang over their wounded to gain the trenches. They required only the lull of reloading. But instantly a second volley prolonged the first. The column staggered, and faces blanched. In a sudden despair they realized the enemy's tactics, for the enemy did have those terrible rifles, after all. From the trenches a low sheet of flame had spread, searing the breasts of rank after rank that pressed against its edge. Scarlet-coated Dragoons, the last of them, flecked the rocks, and over them fell green uniformed troopers, as grass will cover a bloody field, and the Municipal Guards, swaying up from behind, paid out a sprinkling of blue--a ghastly pousse-cafe, as one grim jester described it afterward. The long massed lines wavered. "They've stopped, they've stopped!" cried Rodrigo. "Now we'll close with them, eh, senor--por Dios, _now_!" "All you fellows," shouted Driscoll, "just fill your rifles while they wait. Stopped nothing, Rod! And anyhow, who'd hold the hill if we left it? Who?" The answer came at once, and in dramatic form. One of the pickets stationed on the flank ran among them. "There's another big slew of 'em a-coming!" he yelled excitedly. "Yonder, over yonder!"
