As seen by John William Graham in his book Evolution and Empire, published in London. The preface is dated April 1912. In the chapter An Understanding with Germany he wrote:
With a POD of after April 1912 what are plausible scenarios in which Britain or Germany could buy or push out Portugal from Angola or Mozambique?
We [Britain and Germany] have not a single conflicting interest in the domain of high politics. It is such things as the Bagdad Railway, railways in China, mining concessions in Morocco, the right to buy or otherwise take badly owned or weakly owned lands in Africa, to acquire (say) Mozambique or Angola, if Portugal can be bought or pushed out.
