The Honda Point disaster was the largest peacetime loss of U.S. Navy ships in history. On the foggy and moonless night of September 8, 1923, seven destroyers traveling at 20 knots (37 km/h) ran aground and wrecked at California's Honda Point (also known as Point Pedernales, with offshore outcroppings known as Devil's Jaw). The location was several miles north of the Santa Barbara Channel, the ships' intended route. Two other destroyers grounded, but were able to maneuver free off the rocks. Twenty-three sailors died; 745 were rescued. Navigational errors, compounded by unusual ocean currents attributed to Japan's Great Kantō earthquake, were the likely cause. A court-martial board convicted the squadron's commander Edward H. Watson and the acting navigator Donald T. Hunter, and stripped them of seniority for any future promotions.
