Freeman was the doctor, naturalist and surveyor for an expedition to Ashanti and Jaman, two independent states in the Gold Coast. The expedition set out from Accra on 8 December 1888, with a band consisting of a band-master and six boys playing two side drums and five fifes, three European officers (Freeman, the Commissioner, and the Officer in Charge of the Constables), one Native officer, 100 Hausa constables, a gunners' party with a rocket trough, an apothecary, apothecary's assistant, a hospital orderly, and 200 bearers. The expedition went first to Kumasi (or Coolmassie as it appears in older accounts), the capital of the then independent kingdom of Ashanti. Their second port of call was Bondoukou, Ivory Coast, where they arrived only to find that the king had just signed a protectorate treaty with the French.
