Brothers was launched in the Thirteen Colonies in 1772, probably under another name. From 1785 she became a Bristol-based slave ship. She made six complete voyages in the triangular trade, in all embarking 1880 enslaved people. The French captured her in December 1794 as she was on the first leg of her seventh such voyage and before she had embarked any captives. The main source for this article provided detail on crew turnover and death rates for her first three voyages. The first voyage had a particularly heavy mortality rate among the crew. The main source also provided data for her fourth, fifth, and sixth voyages for mortality rates on the Middle Passage among the enslaved people that she was carrying. Career Brothers first appeared in Lloyd's Register (LR), in the issue for 1786; the 1785 issue is not available online. The absence of a volume for 1785 makes it impossible to see whether the Brothers in the 1784 issue, the former Somersall (or Sommersale), became the Brothers of this article. 1st enslaving voyage (1785–1787): Captain Jeffrey Howlett (or Howlet), sailed from Bristol on 22 July 1785. Brothers arrived at Cape Coast Castle on 16 September, and departed for Benin four days later. On 10 June 1786 she was "well" at Benin with 204 captives. She arrived at St Vincent on 18 January 1787 or 31 January with 220 captives. She sailed for Bristol on 7 March and arrived there on 2 May. Brothers had left Bristol with 40 crew members. She enlisted six more while at Benin. She arrived at St Vincent with 18 crew members, and discharged eight there. She enlisted nine men before she left. She suffered two crew deaths on her way home. In 1787, 32 of Brotherss 55 crew members died. This was the heaviest loss among 203 voyages from Bristol in that year to all destinations. Twenty-three vessels sailed from Bristol for West Africa and the West Indies, and they employed a total of 554 men; of these 554 men, 100 (approximately 18%), died. Death rates were highly variable across vessels: there were no deaths on seven voyages. If one removes Brothers from the calculation, the average death rate drops to a still high 12%. 2nd enslaving voyage (1787–1789): Captain Howlett sailed from Bristol on 6 July 1787. She was reported "well" at Anomaboe on 6 January 1788. She sailed from Cape Coast Castle
