The Battle of Nsamankow: How the Asante Killed a British Governor

The First Anglo-Ashanti War opened with one of the most lopsided defeats Britain suffered anywhere in nineteenth-century West Africa. At the Battle of Nsamankow, fought on January 21, 1824, an Asante army wiped out a British column and killed the sitting governor of the Gold Coast, a blow to imperial prestige that shaped British strategy in the region for decades afterward.

The war grew out of a territorial dispute between the Asante Empire and the Fante, a coastal people allied with Britain. When Sir Charles MacCarthy, the newly appointed governor at Cape Coast, rejected Asante claims in the disputed region, war followed. MacCarthy divided his available forces into several columns meant to converge on the Asante army, but coordination between them broke down almost immediately. His own column, numbering only a few hundred men (regulars from the Royal African Colonial Corps, Cape Coast militia, and Fante auxiliaries), pushed ahead alone through days of heavy rain, camping near a tributary of the Pra River.

Warned that a large Asante force was near, MacCarthy reportedly dismissed the danger, saying he wanted to see how the Asante liked British gunfire. On the afternoon of January 21, an army estimated at 10,000 Asante warriors appeared. In an odd overture, MacCarthy ordered his band to strike up “God Save the King”; the Asante answered with war drums and horns. The exchange settled nothing, and fighting broke out as Asante forces worked to cross the river on felled-tree bridges.

The battle turned on a supply failure. By mid-afternoon the British were nearly out of ammunition, and when a resupply finally reached the line, several of the crates turned out to contain macaroni rather than powder and shot. With his Fante auxiliaries fleeing and his men unable to return fire, MacCarthy made a last stand with a handful of officers beneath a tree. He was shot and, rather than risk capture, is reported to have taken his own life. Ensign Wetherell died defending his body; MacCarthy’s secretary, J.T. Williams, was taken prisoner and, according to his own later account, held for months in a hut alongside the severed heads of MacCarthy and Wetherell, kept by the Asante as trophies of the victory. Of the units engaged that day, well over a hundred British and allied troops were killed.

Nsamankow did not end the war (Britain and Asante fought four more wars over the following seventy-six years), but it exposed how badly Britain had underestimated Asante military organization, and it set the pattern of costly miscalculation that would recur on both sides before the Gold Coast was finally annexed in 1902.
