HMS Blackwall (1696)

Blackwall was a 50-gun fourth-rate ship of the line of the English Royal Navy, launched at Blackwall Yard in 1696.

In September 1705, whilst under the command of Captain Samuel Martin Blackwall, along with two smaller vessels, had been ordered to convoy some merchantmen to the Baltic. On 20 October, as Blackwall and her two consorts were convoying the return voyage, they encountered a superior French force. All the English ships were captured, Blackwall herself being taken by the French ship Protée. Both Captain Martin and the French commander were killed in the action.

Blackwall was commissioned into the French Navy under the name Blekoualle; she was recaptured on 15 March 1708 but was not taken back into service in the Royal Navy, the decision being taken to have her broken up instead. However, she was captured again by the French in 1709, this time being named Blakoual, remaining in French service until disposed of in 1719.
