A quick, sudden flash, half perceived, a sharp, ear-stunning explosion, as of lightning striking near, and an unseen messenger of death ploughs a mangled, horrid furrow through the dense ranks of the Peruvians. A plunging, white sulphurous cloud has burst from one of the guns on the redoubt, and rolls low and stifling over the square. There is a brief instant of stillness, then a moan of terror, broken quickly by yells of wounded men, answered by a second flash and roar. The great doors swing back, their blankness giving place to sudden fell activity as charging columns crash into the open with the battle-cries of Spain. An avalanche of steel-clad men and horses here; another there; a rushing, bellowing phalanx of infantry between. "_Santiago à ellos!_" "_Cristo y San Miguel!_" They strike the fear-numbed mass of the Peruvians, cutting, thrusting, slashing, with resistless fury. The ranks of nobles, silent and motionless a moment ago, are whirled by the shock into a seething, shrieking tumult. Those on the edge of the concourse are hurled back upon their fellows by the tremendous impact, and cut down while they reel. The mail-clad Spaniards, released from the nervous strain of hours’ duration, are seized of blood-madness. Their battle-cries are lost in an infernal chorus of screams of agony, overtopped by the reports of the cannon which thunder savage accompaniment. A pandemonium! An outbreak of hell itself! A horror not to be dwelt upon! The worst of the slaughter is around Atahualpa, whose person the Spaniards are making most desperate efforts to gain; but a large number of his escort, cut off by the charge of De Soto’s troop, have stampeded in wild panic down the narrow streets leading from the plaza. A few escape, but in a moment these avenues are blocked by the crush. De Soto, having perceived at once that the Peruvians are unarmed and that victory—if this atrocity can be so called—-was assured by the very first collision, essays gallantly to check the worse than useless butchery. His commands are unheard. He snatches his trumpeter’s instrument and blows the recall—blows again and again. As well shout injunctions to a tornado, or call to a pack of wolves. He drives among his men, striking up their weapons. De Piedra, enraged by his interference, aims a cut at him, and is unhelmed and unhorsed by a blow from the captain’s mace. Well struck, De Soto! Pity it had not been better; for Piedra will be breathing again before an hour has passed. But De Soto finds it perilous work. In a moment his horse is wounded by a pikeman, and rearing, slips and is down. Steed and rider are lost in the confusion: at last, up again, the captain unhurt. It is some minutes before he is mounted, and meanwhile a wall of stone and adobe forming part of the enclosure of the square has given away before the crush of the fear-driven horde, and they burst through the break in a huge struggling torrent.
