The city of Omner had been captured by the Lamanites previously (see Alma 51:26). Now in the recapture story, nothing is said about the city of Omner. Why? Perhaps because the Lamanites had abandoned it. Perhaps because it was small or unimportant. Perhaps because of some other reason. [Alan C. Miner, Personal Notes]
