Thomas Plunket
Irish soldier in the British army

Corporal Thomas Plunket (1785 – 1839) was an Irish soldier who served in the British Army during the Napoleonic Wars. Serving as a rifleman in the 95th Rifles, he fought in the British invasions of the River Plate, Peninsular War and Waterloo campaign. Plunket is best known for killing French Brigade-general Auguste François-Marie de Colbert-Chabanais at the Battle of Cacabelos at a long distance with his Baker rifle.
Early life
Thomas Plunket was born in 1785 in Newtown, County Wexford. He enlisted the British Army's 95th Rifles in May 1805, and in 1807 was sent to South America to participate in the British invasions of the River Plate. During an engagement with Spanish forces in Buenos Aires, Plunket killed approximately 20 Spanish soldiers while sniping from a rooftop alongside other members of his unit, before retreating when Spanish artillery attacked their position with grapeshot. Plunket also shot and killed a Spanish officer waving a white handkerchief who was possibly attempting to arrange a truce, which resulted in more Spanish artillery bombardments, ultimately contributing to the British surrender and the end of the invasions.
Peninsular War
In 1808, Plunket was sent to the Iberian Peninsula to fight against French forces as part of the Peninsular War. Landing in Portugal, he was part of a British army under Lieutenant-General John Moore which advanced into Spain in late 1808. However, as Napoleon personally arrived to command French forces in the conflict, Moore's army was forced to withdraw from Spain and conducted a fighting retreat to Corunna in early 1809.

Why this record matters
“Thomas Plunket” is worth following because a concise public description often conceals a longer documentary argument. Here, Thomas, Plunket and Irish provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 25, 2026. The linked authority identifier is Q7793196. VIAF identifies the subject as 170831501. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1785, 1839, 1805 and 1807.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
