Natives from 'protected' tribes are summoned with a bell and shouts to act as bearers or carriers for the British in the 2nd Ashanti War (1873-74). In 1873, after decades of an uneasy relationship between the British and the Acing people of central Ghana, the British attacked and virtually destroyed the Asanti capital of Kumasi, and officially declared Ghana a crown colony on 24 July 1874. After this they moved their administrative capital from Cape Coast Castle to Accra.
