at the Philadelphia Navy Yard on 19 June 1863. Repairs completed, Wachusett was recommissioned on 28 January 1864. On 4 February, she sailed for the coast of Brazil to protect American commerce from the Confederacy's "piratical cruisers," particularly Alabama and Florida. Many months passed tracking down fruitless leads as to the whereabouts of the two vessels. Finally, on 4 October, Comdr. Napoleon Collins of Wachusett sighted Florida, Lt. Charles Manigault Morris, CSN, entering Bahia harbor, Brazil. Comdr. Collins dared Lt. Morris to come out and fight, but the Confederate captain prudently declined. However, Collins was determined not to allow Florida to slip away. In the early morning darkness of the 7th, Wachusett got underway, steamed past the Brazilian gunboat anchored between his ship and Florida, and rammed the raider on her starboard quarter. After a brief exchange of cannon fire, Lt. Porter, commanding Florida in Morris's absence, surrendered the ship. Aroused by the commotion, the Brazilian coastal fort at Bahia opened fire on Wachusett as she towed her prize to sea. The two vessels escaped unscathed, steamed north, and reached Hampton Roads, Virginia, on 11 November. Commander Collins was promptly court-martialed for the Bahia incident, but soon after was restored to his command by U.S. Secretary of the Navy Gideon Welles. Post-Civil War service After undergoing repairs at the Boston Navy Yard, Wachusett, under its new captain, Commander Robert Townsend, got underway on 5 March 1865 and sailed, via the Cape of Good Hope, for the East Indies. There, she joined Wyoming and Iroquois in an effort to track down the Confederate commerce raider CSS Shenandoah. While in China the ship was engaged in efforts to track down outlaws and pirates who were harming American interests. In mid-August the ship sailed up the Yangtze River in this mission. The heat was reportedly 107 degrees Fahrenheit (42 °C) in the shade and the ship made difficult passage up the river. A number of cases of heat stroke, some of them fatal, occurred. At 1:45 am on 15 August 1866, Robert Townsend died of heat stroke. The executive officer John Woodward (Jack) Philip, (later Admiral) assumed command of the Wachusett and sailed it downriver with the goal of making it to Japan for the health of the crew. That evening the ship anchored by the consulate in Shanghai and held a funeral for their commander. She remained in Chinese waters into 1867,
