The first of the Anglo-Ashanti wars occurred in 1823. In these conflicts, the Ashanti Kingdom faced off, with varying degrees of success, against the British Empire residing on the coast. The root of the conflict traces back to 1823 when Sir Charles MacCarthy, resisting all overtures by the Ashanti to negotiate, led an invading force. The Ashanti defeated this, killed MacCarthy, took his head for a trophy and swept on to the coast. However, disease forced them back. The Ashanti were so successful in subsequent fighting that in 1826 they again moved on the coast. At first they fought very impressively in an open battle against superior numbers of British allied forces, including Denkyirans. However, the novelty of British rockets caused the Ashanti army to withdraw. In 1831, a treaty led to 30 years of peace, with the Pra River accepted as the border.
