Well had it been for Almagro, if he had remained firm on the post which gave him such advantage. But from a false point of honor, he thought it derogatory to a brave knight passively to await the assault, and, ordering his own men to charge, the hostile squadrons, rapidly advancing against each other, met midway on the plain. The shock was terrible. Horse and rider reeled under the force of it. The spears flew into shivers;24 and the cavaliers, drawing their swords, or wielding their maces and battle-axes,--though some of the royal troopers were armed only with a common axe,--dealt their blows with all the fury of civil hate. It was a fearful struggle, not merely of man against man, but, to use the words of an eyewitness, of brother against brother, and friend against friend.25 No quarter was asked; for the wrench that had been strong enough to tear asunder the dearest ties of kindred left no hold for humanity. The excellent arms of the Almagrians counterbalanced the odds of numbers;but the royal partisans gained some advantage by striking at the horses instead of the mailed bodies of their antagonists.

The infantry, meanwhile, on both sides, kept up a sharp cross-fire from their arquebuses, which did execution on the ranks of the cavaliers, as well as on one another. But Almagro's battery of heavy guns, now well directed, mowed down the advancing columns of foot. The latter, staggering, began to fall back from the terrible fire, when Francisco de Carbajal, throwing himself before them, cried out, "Shame on you, my men! Do you give way now? I am twice as good a mark for the enemy as any of you!" He was a very large man; and, throwing off his steel helmet and cuirass, that he might have no advantage over his followers, he remained lightly attired in his cotton doublet, when, swinging his partisan over his head, he sprang boldly forward through blinding volumes of smoke and a tempest of musket-balls, and, supported by the bravest of his troops, overpowered the gunners, and made himself master of their pieces.
