HMS Captain (1743)

HMS Captain was a 70-gun third rate ship of the line of the Royal Navy, built according to the 1733 proposals of the 1719 Establishment at Woolwich Dockyard, and launched on 14 April 1743.

In 1760, Captain was reduced to a 64-gun ship. Then in 1777 she was converted to serve as a storeship and renamed Buffalo. Buffalo remained in this role until she was broken up in 1783.

Although a storeship, Buffalo shared, with HMS Thetis (1773), and HMS Alarm (1763), in the proceeds from HMS Southampton (1757)'s capture of the 12-gun French privateer Comte de Maurepas, on 3 August 1780.
