Lieutenant-General Sir William Inglis, KCB (1764 – 29 November 1835) was a British Army officer who served in the French Revolutionary and Napoleonic Wars.

The same year, Inglis and his men were also briefly detached to a failed expedition to Brittany, but by the time the campaign had faltered in the winter of 1794, Ingis was back in Belgium.

In 1796, Inglis and his regiment were posted to the West Indies, arriving in early 1796 as the only vessel of the convoy to make it safely across the Atlantic Ocean on the ship Charon.

[3] Due to the consequent paucity of soldiers, Inglis was prominently involved in the British invasion of St. Lucia and the capture of the Morne Fortuné fort.

[3] The regiment left the Channel Islands in 1809 after five years and was attached to Sir Arthur Wellesley's army in Portugal for service in the Peninsular War.

The British force present on the field was commanded by General William Beresford, and tactical mistakes by him resulted in the destruction of its left by French cavalry early in the engagement.

Hoghton was killed in the fighting, and Inglis himself was struck by a 4 lb grapeshot, the missile penetrating his neck and entering his shoulder, lodging in his upper back, causing severe blood loss and pain.

Refusing offers of assistance to be withdrawn from the fight, Inglis lay wounded with the Regiment's Colours just behind the 57th's beleaguered lines as its ranks dwindled having lost two-thirds of its strength under the surrounding weight of overwhelming French numbers and the devastating fire to which it was being repeatedly subjected, from where, amidst the maelstrom, he could be heard shouting the exhortation repeatedly "Die hard 57th, die hard!"

[3][4] However, in spite of the pressure and extensive casualties sustained from the French advancing masses the 57th's line just held, and the French troops, apparently losing heart from the casualties they were sustaining from the ferocity of its concentrated volley fire, faltered in their forward momentum, and subsequently broke and retreated due to the arrival of other British forces threatening them from elsewhere upon the field, the British going on to win the battle.

"[3] Inglis' wounds were so severe that he was forced to return to Britain to recuperate and consequently missed the succeeding two years of the Peninsular War, spending much of 1812 running a court-martial board in Lisbon.
