Alma 43:38

while on the other hand, there was now and then a man fell among the Nephites, by their swords, and the loss of blood; 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 breast-plates, and their arm-shields, and their head-plates; and thus the Nephites did carry on the work of death among the Lamanites.

Once in a while, a Nephite soldier fell from their swords and lost blood. But the Nephite soldiers were protected on the important parts of their bodies by their chest armor, arm shields, and head plates. And so the Nephites kept killing many Lamanites.

Meanwhile, only a few Nephites fell from sword wounds and blood loss. Their armor shielded the vital parts of their bodies—their breastplates, arm shields, and helmets protected them from the worst of the Lamanite strikes. And so the Nephites dealt death among the Lamanites.
