Question: Why is Captain Moroni regarded as one of the greatest military leaders in the history of the Nephites?
Answer: There are several reasons Moroni was, and is, regarded as a great military leader.
(1) He was a man of God.
“Yea, verily, verily I say unto you, if all men had been, and were, and ever would be, like unto Moroni, behold, the very powers of hell would have been shaken forever; yea, the devil would never have power over the hearts of the children of men. Behold, he was a man like unto Ammon, the son of Mosiah, yea, and even the other sons of Mosiah, yea, and also Alma and his sons, for they were all men of God” (Alma 48:17-18).
(2) He obtained and heeded the words of a prophet.
“But it came to pass, as soon as they had departed into the wilderness Moroni sent spies into the wilderness to watch their camp; and Moroni, also, knowing of the prophecies of Alma, sent certain men unto him, desiring him that he should inquire of he Lord whither the armies of the Nephites should go to defend themselves against the Lamanites” (Alma 43:23).
(3) He was concerned for the well-being of all who served under his command.
“And thus they were prepared, yea, a body of their strongest men, with their swords and their slings, to smite down all who should attempt to come into their place of security by the place of entrance, and thus were they prepared to defend themselves against the Lamanites” (Alma 49:20).
(4) He used strategy to overcome his opponents.
“And he also knowing that it was the only desire of the Nephites to preserve their lands, and 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” (Alma 43:30).
(5) He was patriotic.
“And it came to pass that he rent his coat; and he took a piece thereof, and wrote upon it–‘In memory of our God, our religion, and freedom, and our peace, our wives, and our children–‘ and he fastened it upon the end of a pole...and he took the pole, which had on the end thereof his rent coat, (and he called it the title of liberty) and he bowed himself to the earth, and he prayed mightily unto his God for the blessings of liberty to rest upon his brethren, so long as there should be a band of Christians remain to possess the land--” (Alma 46:12, 13).
