33 And now as Moroni knew the intention of the Lamanites, that it was their intention to destroy their brethren, or to subject them and bring them into bondage, that they might establish a kingdom unto themselves, over all the land;
34 And he also knowing that it was the only desire of the Nephites to preserve their lands, their liberty, and their church, therefore he thought it no sin that he should defend them by stratagem; therefore he found, by his spies, which course the Lamanites were to take.
35 Therefore he divided his army, and brought a part over into the valley, and concealed them on the east, and on the south of the hill Riplah; and the remainder he concealed in the west valley, on the west of the river Sidon, and so down into the borders of the land of Manti.
36 And thus having placed his army according to his desire, he was prepared to meet them.
37 And it came to pass that the Lamanites came up on the north of the north where a part of the army of Moroni was concealed.
38 And as the Lamanites had passed the hill Riplah, and come into the valley, and began to cross the river Sidon, the army which was concealed on the south of the hill, which was led by a man whose name was Lehi; and he led his army forth and encircled the Lamanites about, on the east in their rear.
39 And it came to pass that the Lamanites, when they saw the Nephites coming upon them in their rear, turned them about, and began to contend with the army of Lehi; and the work of death commenced, on both sides;
40 But it was more dreadful on the part of the Lamanites; for their nakedness was exposed to the heavy blows of the Nephites, with their swords and their cimeters, which brought death almost at every stroke; while on the other hand, there was now and then a man fell among the Nephites, by their swords and the loss of blood;
41 They being shielded from the more vital parts of the body, or the more vital parts of the body being shielded from the strokes of the Lamanites, by their breastplates, and their arm-shields, and their head-plates; and thus the Nephites did carry on the work of death among the Lamanites.
42 And it came to pass that the Lamanites became frightened, because of the great destruction among them, even until they began to flee towards the river Sidon.
43 And they were pursued by Lehi and his men, and they were driven by Lehi into the waters of Sidon; and they crossed the waters of Sidon.
