The Third Anglo-Ashanti War and the Burning of Kumasi, 1873–1874

By the early 1870s, tension between Britain and the Asante Empire over control of the Gold Coast had been building for decades. In 1869 Britain took possession of the coastal fort of Elmina, territory the Asante regarded as under their own jurisdiction, and in 1873 Asante forces moved to occupy the coastal provinces. Britain responded by sending an expeditionary force under Major-General Sir Garnet Wolseley, a campaign remembered among Asante and British troops alike as the “Sagrenti War,” an Asante rendering of Wolseley’s own name.

Wolseley’s force combined British regulars, including the Black Watch and the Rifle Brigade, with African and Indian troops, and carried advantages the Asante had not faced in earlier wars: quinine to reduce losses to malaria, more reliable modern rifles, and artillery. The decisive engagement came at the Battle of Amoafo on January 31, 1874. The Asante army, commanded by the Bantamahene Amankwatia, chose strong defensive ground in forest and swamp and fought with a discipline that impressed British officers: accounts describe roughly one in four British soldiers hit by Asante gunfire during the fighting, and Amankwatia himself was killed directing the defense. But British firepower told: Asante losses are estimated in the range of 2,000 killed or wounded, against a few dozen British and allied dead, and the road to the Asante capital, Kumasi, lay open. A smaller follow-up engagement at Ordashu two days later confirmed the British breakthrough.

Kumasi’s rulers and residents abandoned the city before Wolseley’s column arrived on February 4, 1874, making a negotiated surrender in the field impossible. British troops occupied the largely empty capital, looted and destroyed the royal palace with explosives, and burned much of the city before withdrawing, a deliberate demonstration of force rather than an attempt at permanent occupation. Wolseley’s entire campaign, from landing to withdrawal, took roughly two months; he pulled his troops out before the onset of the rainy season, when disease historically inflicted the heaviest casualties on European forces in West Africa.

The war ended with the Treaty of Fomena, signed in July 1874 by Asantehene Kofi Karikari. Its terms required Asante to pay a war indemnity of 50,000 ounces of gold, renounce claims to Elmina and other coastal territory, guarantee free trade routes to the coast, and formally end the practice of human sacrifice in Asante ritual life. The treaty did not end Asante independence outright, but it broke the empire’s military parity with Britain and set the terms for the fourth and fifth Anglo-Ashanti wars that followed within a generation, ending in full British annexation in 1902.
