And it came to pass in that same year there began to be a war again between the Nephites and the Lamanites. And notwithstanding I being young, was large in stature; therefore the people of Nephi appointed me that I should be their leader, or the leader of their armies. Therefore it came to pass that in my sixteenth year I did go forth at the head of an army of the Nephites, against the Lamanites; therefore three hundred and twenty and six years had passed away.
