Gid was a Nephite city on the east borders by the seashore, listed among the cities Amalickiah took possession of during his offensive against the Nephites, alongside Nephihah, Lehi, Morianton, Omner, and Mulek (Alma 51:26).
Under Lamanite control, Gid held Nephite prisoners of war. Moroni, knowing where the captives were guarded, searched his men for a descendant of Laman and found one named Laman, a former servant of the king whom Amalickiah had murdered. Moroni sent him with a small party to the guards. Laman told the guards he was a Lamanite who had escaped the Nephites with their wine; he held the wine back until the guards, weary, pressed him for it, then let them drink freely. The wine was strong, and the guards became drunk and fell into a deep sleep. Moroni armed the prisoners—men, women, and children able to bear arms—then surrounded the Lamanite army by night. Waking surrounded, with the prisoners armed inside the walls, the Lamanite captains surrendered their weapons without a fight. Moroni took the city, freed the Nephite prisoners, who joined his army (Alma 55:7-24).
Moroni then had the captured Lamanites strengthen the fortifications around Gid, after which he sent the prisoners to the city Bountiful and guarded it with a strong force (Alma 55:25-26).
Later, Nephi and Lehi, the sons of Helaman, traveled from city to city preaching, going from Bountiful to Gid and from Gid to Mulek among the people of Nephi in the land southward (Helaman 5:14-16).
