Teomner was a Nephite military officer, noted for his role in a strategic military operation led by the commander Helaman around 63 B.C. This operation aimed to regain control of the city of Manti, which had been captured by the Lamanite forces. As part of Helaman’s strategic plan, Teomner was tasked with a crucial role. Alongside another officer named Gid, Teomner commanded a small contingent of men. Both Gid and Teomner’s forces were hidden in strategic locations around the city of Manti, as Helaman led the main body of the Nephite army to entice the Lamanite forces out of the city (Alma 58:16–17).
When Helaman and his forces engaged with the Lamanite army and subsequently feigned a retreat into the wilderness, the Lamanites, eager to pursue and destroy them, vacated the city of Manti. This provided Teomner and Gid the opportunity to emerge from their concealed positions and recapture the city, effectively trapping the Lamanites outside their fortified refuge. This operation was executed with such success that Manti was taken without the loss of Nephite blood, highlighting the Nephite forces’ strategic cunning and the effectiveness of Teomner and his men in the endeavor (Alma 58:20–23).
In the aftermath of the operation, the Nephite forces were able to reclaim not only Manti but other cities as well, thanks to their trust in God and the victory He provided them. Teomner, although only mentioned once in the record, played a significant role in these military achievements, which were documented in Helaman’s epistle to Captain Moroni (Alma 58:32–33). His actions alongside his fellow soldiers contributed to the Nephite’s ability to maintain control over their cities and the lands they had rightfully possessed.
