Lieutenant-General Sir Charles William Doyle, GCH, CB (1770 – 25 October 1842) was a British Army officer who served during the Napoleonic Wars.

[1] Doyle entered the army as an ensign in the 14th Foot, which was commanded by his uncle, Welbore, on 28 April 1783, and was promoted lieutenant on 12 February 1793, in which year he accompanied his regiment to the Netherlands.

The 14th Foot was one of the 'ragged' regiments which Harry Calvert compares in his Letters to Falstaff's soldiers, but Major-General Ralph Abercromby soon got them into better condition, in which task he was helped by Doyle, whom he appointed his brigade-major.

Doyle was publicly thanked by Abercromby for carrying a redoubt in the heights above Valenciennes, and then acted as orderly officer to the Austrian generals during the siege of that town, when he was wounded in the head.

He accompanied this regiment to the West Indies in 1796, and acted first as brigade-major and then as aide-de-camp to Abercromby, whose public thanks he received in 1797 for covering the embarkation of the troops from the Puerto Rico, as also those of the Governor of Barbados in 1798 for having in an open boat with only thirty soldiers driven off a dangerous French privateer, and retaken two of her prizes.

He was attached to Lord Cavan's brigade, and was present with it at Cadiz and Malta, and finally in Egypt, where he served in the battles of Abukir, Mandara, and Alexandria, in the latter of which he was severely wounded.

These services were greatly praised in Sir Henry Wellesley's despatches, and on 4 June 1813 Doyle was appointed an aide-de-camp to the Prince Regent, and promoted to the rank of colonel in the British Army.
