American forces included the frigate USS United States and the two sloops-of-war USS Dale and USS Cyane. The squadron arrived in Monterey Bay on October 19 and anchored. Commodore Jones sent his second in command Captain James Armstrong ashore to demand a Mexican surrender by 9:00 am the following morning. The Mexican garrison consisted of only 58 men in an old fort who chose not to resist so when 9:00 am came, fifty American marines and 100 sailors landed and captured the city without incident. It wasn't until the next day that Commodore Jones learned that war had not begun between the United States and Mexico and that the British were not preparing to take control of California. The Mexican troops were freed and the landing party boarded their ships and set sail, saluting the Mexican flag as they exited the harbor. Jones headed for Hawaii, which was just taken over by the British, and he helped restore the Kingdom of Hawaii. The incident proved unpopular in Mexico and in response Monterey's garrison constructed shore batteries and other defenses to guard their city from future attack which came in 1846 during the Mexican War. Thomas ap Catesby Jones was relieved of duty though he eventually served in the war with Mexico.
