Action of 7 December 1804
naval action during the Napoleonic Wars

The action of 7 December 1804 was a minor naval action that took place at the beginning of the Napoleonic Wars. Royal Navy ship-of-the-line HMS Polyphemus (64) under the command of Captain John Lawford, and the frigate HMS Lively (38) under the command of Captain Graham Hamond captured the Spanish frigate Santa Gertrudis off Cape Santa Maria.
After the outbreak of war with France and Spain in 1804, the Royal Navy's HMS Polyphemus and HMS Lively were cruising off the coast of Spain and had captured several Spanish ships.
On 7 December a sail was spotted off the coast of Cape Santa Maria. Polyphemus and Lively intercepted and after a short action overhauled the frigate. The Spanish captain seeing that resistance was useless stuck the colours.
Santa Gertrudis a frigate of 40-guns, was armed only with fourteen, and was sailing from Peru and Mexico to Coruna when Polyphemus captured her. Polyphemus and Santa Gertrudis separated in a gale that damaged the Spanish ship, which nonetheless reached Plymouth on 10 January 1805, in tow by the armed defence ship Harriet, which had encountered Santa Gertrudis some days after the gale.
Santa Gertrudis was carrying $1,215,000, and merchandize. The prize money was shared, making the captains rich for life.

Why this record matters
The phrase “naval action during the Napoleonic Wars” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q29075395. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1804 and 1805.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
