A Dictionary of the Book of Mormon/Teomer
TEOMER. A prominent Nephite military officer in the days of the Judges. In the war brought on by the treason and ambition of Amalickiah, he served under Helaman in the army of the southwest. Teomer took a prominent part in the siege and recapture of the city of Manti (B. C. 63), at which time he had command of one of the divisions of the Nephite army. When the Lamanites within the city, fearing that the besieging Nephite army would cut them off from their supplies, made a sortie and endeavored to drive them away, the main body of Helaman's troops retreated, while Gid and his men, and Teomer with his command, who were hid in the wilderness, fell in the Lamanite rear, cut off communication between the advancing army and the city, and then unexpectedly fell on the very small guard which the Lamanite commander had incautiously left to take care of Manti. The guard was easily overpowered, and Gid and Teomer obtained and retained possession of the city; during which time the main body of the Lamanites were out-generaled by Helaman, who led them afar off into the wilderness, and then by a rapid counter march, during the night, reached Manti before them.
