Occasion:

In 1872 some Dutch possessions on the Gold Coast were transferred to Great Britain. The King of Ashanti claimed a tribute formerly allowed to him by the Dutch and refused to evacuate the territory ceded to Britain. He also held four Europeans in captivity. The British Government determined to take up the matter seriously, and when in January 1873 an Ashanti force invaded the British Protectorate an expedition under Sir Garnet Wolseley was immediately despatched.
