on the 19th and visited Copenhagen until 2 August when she sailed for Sweden. She arrived at Stockholm five days later and remained at that Baltic port until the 16th. On her voyage back south, the frigate touched again at Copenhagen, and spent much of the autumn at Bremerhaven before heading for the Mediterranean. She reached Port Mahon, Minorca, in the Balearics, on 3 December 1849. At that time, political conditions in Europe were still unstable in the aftermath of the revolutions which had shaken Europe in 1848; and the American naval force in the Mediterranean had been increased to its greatest strength since the First Barbary War and the Second Barbary War. During the protracted series of crises, it had been a source of stability in the area without offending any nation or faction. In the summer of 1850, when tension in Europe began to subside, St. Lawrence was ordered to proceed once more to the Baltic for a short cruise before returning home. She touched at Boston, Massachusetts on 1 November, reached New York on the 6th, and was decommissioned there on the 15th. Voyage to England, 1851 Recommissioned on 5 February 1851, Commander Joshua R. Sands in command, the frigate departed New York on the 20th, carrying to England the exhibits from the United States for the Great Exhibition at London, the first modern world's fair. On her return voyage from this interesting assignment, she gave the United States chargé d'affaires in Portugal passage from Southampton to Lisbon. The ship reached New York on 11 August and decommissioned there a week later. Pacific Squadron, 1851–1855 Recommissioned on 18 November 1851, St. Lawrence sailed on 12 December for the Pacific. For the next three and one-half years, she cruised along the west coast of North and South America, from Cape Horn to Puget Sound, occasionally venturing as far west as the Sandwich (Hawaiian) Islands. In 1853, she relieved as flagship of the Pacific Squadron and continued this duty until she relinquished her role as flagship to on 2 February 1855. She departed Valparaíso five days later and arrived at Hampton Roads on 21 April. She was decommissioned and placed in ordinary at Norfolk, Virginia exactly a month later. Brazil Squadron, 1856–1859 Recommissioned on 22 September 1856, St. Lawrence sailed for the Atlantic coast of South America to become flagship of the Brazil Squadron early the next year. Her
