Antiparah was a Nephite city captured by the Lamanites around 64 B.C. during the invasion begun under Amalickiah. It lay in the southwestern part of the land near a pass leading to the west sea. Helaman lists it among the cities the Lamanites took by force, alongside Manti, Zeezrom, and Cumeni (Alma 56:14). The Lamanites stationed their strongest and most numerous army there (Alma 56:34).
To draw that army out, Antipus had Helaman march his two thousand stripling Ammonite warriors past Antiparah as if carrying provisions to a city by the seashore. The Lamanite force pursued them northward; Antipus followed with part of his army. After a running pursuit of several days, the Lamanites halted and Helaman’s men turned to face them. Antipus had overtaken the Lamanites and a battle was already underway, but Antipus had fallen by the sword and his men were giving way. Helaman’s two thousand struck the Lamanite rear, the men of Antipus rallied, and together they surrounded the Lamanites and forced their surrender. Not one of Helaman’s two thousand was killed (Alma 56:31-56).
Ammoron later offered to give up Antiparah in exchange for the prisoners of war, but Helaman refused the exchange, and Ammoron in turn refused. As the Nephites prepared to take the city by force, the people of Antiparah abandoned it and fled to fortify their other cities, and Antiparah fell into Nephite hands without a fight (Alma 57:1-4).
