Lehi was a pivotal Nephite military commander during the protracted struggles described in the Book of Alma. Known for his valor and strategic acumen, Lehi first emerged as a leader when he cleverly encircled the Lamanite forces in the valley east of the river Sidon, effectively contributing to the routing of the enemy and pushing them into the path of Moroni’s army (Alma 43:35, 39). His battlefield exploits gained him such renown that when appointed as chief captain over the city of Noah, the mere knowledge of his command caused trepidation among the Lamanite ranks, leading to a decisive victory in which the Lamanite forces sustained significant losses (Alma 49:16-24).
Lehi’s military prowess was further demonstrated in the capture of the city of Mulek. Together with Teancum, his forces managed to trap the Lamanites between themselves and Moroni’s forces, leading to a crushing defeat for the enemy (Alma 52:27-36). After this success, Moroni honored Lehi with command over the newly recaptured city, reflecting his high level of trust and respect for Lehi’s leadership and abilities (Alma 53:2).
In subsequent conflicts, Moroni and Lehi orchestrated a strategic encirclement of the Lamanites in the land of Moroni, resulting in the cessation of a long and wearisome war (Alma 62:33-34). Lehi was designated as a key leader alongside Teancum to oversee the Nephite armies during Moroni’s absence to address political turmoil within the Nephite government, signifying his capability to handle military affairs independently (Alma 62:3). Lastly, Lehi once again demonstrated his adept leadership by assisting Moronihah in repelling a Lamanite army, led by Coriantumr, from reaching the land Bountiful.
Throughout his various military campaigns, Lehi was not merely recognized for his effectiveness in battle but also for his noble character. He was described in terms complementary to Captain Moroni, known for his integrity and dedication to the cause of freedom. Lehi was esteemed as “a man like unto Moroni” and beloved by the people, an indication of the profound impact he had not only as a commander but also as a righteous influencer among the Nephites (Alma 53:2).
