This is the story of the second ship to bear the name HMS Cossack.
Originally ordered by Russia for the Black Sea Fleet in December 1852 at a cost of 290,000 silver roubles, the ship was sold to the Hamburg trading house of Henry Mersk & Co. when relations between Britain and Russia deteriorated, as Russia feared possible confiscation.
The original contract price for the vessel, then named Witjas (Cossack), was £46,198, including £16,750 for machinery. The Admiralty subsequently paid the contractors £9,591 to complete the contract (of which £4,187 was for machinery), plus £751 for tonnage exceeding the specification and £2,206 for modifications for His Majesty’s service. The ship remained in service until 1875.
