Eminsang still refused to pay the wages of the porters, however, leading Brantuo to complain to Asante chief Akyempon Yaw, who regulated Elmina affairs in Kumasi.
Eventually, Pieter de Heer managed to persuade Asantehene Kwaku Dua to release Eminsang to send him for trial by the Dutch governor in Elmina.
[7] When it became apparent that the Dutch were negotiating a treaty to transfer their possessions on the Gold Coast to the United Kingdom, Eminsang led the attempts by the Elminese to stop the transfer, and together with other Dutch loyalists paid for a visit to The Hague by David Mill Graves, in an ultimate attempt to stop the ratification of the treaty.
[8] After it became clear that Mill Graves's mission could not prevent the handing over of Elmina to the British, Eminsang withdrew his protest, keen on keeping his influential positions in the colonial government.
Eminsang's volte face proved very worthwhile for him, as he was appointed member of the Committee for the Regularisation of the Affairs of the Netherlands on the Coast of Guinea headed by J. M. C. W. Joost, as well as notary and public registrar.
[10][11] In the preface of his book Fanti Customary Laws,[12] John Mensah Sarbah wrote: Dear Mr. Eminsang, — Pardon the liberty I take in sending you this open letter, with this my first attempt in the Thorny paths of literature.
Eminsang married Mary Ellen De Lyons on 14 April 1860 at the American Episcopal Church in Harper, Liberia.
Eminsang then tried to indict Ussher for fornication and adultery at the Cape Coast court of justice, but after this attempt failed he decided to divorce De Lyons.
