Admiral Sir Benjamin Caldwell, GCB (31 January 1739 – November 1820) was a senior and experienced British Royal Navy officer of the eighteenth century.

As a result of these disputes, Caldwell was overlooked for future employment and only received recognition for his service from King George IV months before his death.

A more permanent commission was not however forthcoming until 1793, when at the outbreak of the French Revolutionary Wars, Caldwell was promoted to rear-admiral, raising his flag in HMS Cumberland.

[1] Caldwell moved from the Cumberland after only a short period and took over HMS Impregnable, a 98-gun second rate in the Channel Fleet of Admiral Lord Howe.

Impregnable was heavily engaged in the action and suffered 31 casualties but along with many officers, Caldwell was overlooked in Howe's dispatch to the Admiralty.

Perceiving this second slight to be a consequence of the first, Caldwell returned to England at once and refused to serve at sea again even if the Admiralty, who had been unimpressed by his attitude, offered him employment, which they did not.
