<P> The retired ship of the line USS Independence was brought back into service, cut down and recommissioned as a razee frigate in 1846 . The newly reconfigured ship removed the old top deck and reduced the gun count from ninety to fifty - four making her less well gunned but much easier to sail . The rebuilt USS Independence, now classified as a heavy frigate, launched on 4 August 1846 when the nation was already at war with Mexico and departed Boston 29 August 1846 for California . She entered Monterey Bay on 22 January 1847 after a fast 146 - day trip around Cape Horn and became the flagship of Commodore William Shubrick, now commanding the Pacific Squadron . </P> <P> In July 1846, Colonel Jonathan D. Stevenson of New York was asked to raise a volunteer regiment of ten companies of seventy - seven men each to go to California with the understanding that they would be muster out and stay in California . They were designated the 1st Regiment of New York Volunteers and fought in the California Campaign and the Pacific Coast Campaign . In August and September the regiment trained and prepared for the trip to California . Three private merchant ships, Thomas H Perkins, Loo Choo, and Susan Drew, were chartered, and the sloop USS Preble was assigned convoy detail . On 26 September the four ships left New York for California . Fifty men who had been left behind for various reasons sailed on 13 November 1846 on the small storeship USS Brutus . The Susan Drew and Loo Choo reached Valparaiso, Chile by 20 January 1847 and after getting fresh supplies, water and wood were on their way again by 23 January . The Perkins did not stop until San Francisco, reaching port on 6 March 1847 . The Susan Drew arrived on 20 March 1847 and the Loo Choo arrived on 26 March 1847, 183 days after leaving New York . The Brutus finally arrived on 17 April 1847 . </P> <P> After desertions and deaths in transit the four ships brought 648 men to California . The companies were then deployed throughout Upper - Alta and Lower - Baja California from San Francisco to La Paz, Mexico . The ship Isabella sailed from Philadelphia on 16 August 1847, with a detachment of one hundred soldiers, and arrived in California on 18 February 1847, the following year, at about the same time that the ship Sweden arrived with another detachment of soldiers . These soldiers were added to the existing companies of Jonathan D. Stevenson's 1st Regiment of New York Volunteers . These troops essentially took over all of the Pacific Squadron's on - shore military and garrison duties and the California Battalion and Mormon Battalion's garrison duties as well as some Baja California duties . </P> <P> After Alta California was secure most of the squadron proceeded down the Pacific coast capturing all major Baja California Peninsula cities and capturing or destroying nearly all Mexican vessels in the Gulf of California . Other mainland ports, not on the peninsula, were taken as well . The objective of the campaign was to take Mazatlan, a major supply base for Mexican forces . USS Cyane was given credit for eighteen captures and numerous destroyed ships . Entering the Gulf of California, Independence, Congress and Cyane seized La Paz on the Baja California Peninsula, and captured and or burned the small Mexican fleet at Guaymas across the Gulf on the mainland . Within a month, they cleared the Gulf of hostile ships, destroying or capturing thirty vessels . Later on their sailors and marines captured the town of Mazatlan, Mexico, on 11 November 1847 . A Mexican campaign to retake the various captured ports resulted in several small battles and at least two sieges occurred in which the Pacific Squadron ships provided support . USS Cyane returned to Norfolk on 9 October 1848 to receive the congratulations of the Secretary of the Navy for her significant contributions to American victories in Mexico . Other ships headed home too . The Treaty of Guadalupe Hidalgo, signed in February 1848 and its subsequent ratification by the United States and Mexican legislatures, marked the end of the Mexican - American War . </P>
