In 1872 British influence over the Gold Coast increased further when Britain purchased the Dutch Gold Coast. The Asante, who for years had considered the Dutch at Elmina as their allies, thereby lost their last trade outlet to the sea. To prevent this loss and to ensure that revenue received from that post continued, the Asante staged their last invasion of the coast in 1873. After early successes, they finally came up against well-trained British forces who compelled them to retreat beyond the Pra River. Later attempts to negotiate a settlement with the British were rejected by the commander of their forces, Major General Sir Garnet Wolseley. To settle the Asante problem permanently, the British invaded Asante with a sizeable military force. The attack, launched in January 1874 by 2,500 British soldiers and large numbers of African auxiliaries, resulted in the occupation and burning of Kumasi, the Asante capital.
