In World War I, the British invaded Cameroon from Nigeria in 1914 in the Kamerun campaign, with the last German fort in the country surrendering in February 1916. After the war, this colony was partitioned between the United Kingdom and France under June 28, 1919 League of Nations mandates (Class B). France gained the larger geographical share, transferred Neukamerun back to neighboring French colonies, and ruled the rest from Yaoundé as Cameroun (French Cameroons). Britain's territory, a strip bordering Nigeria from the sea to Lake Chad, with an equal population was ruled from Lagos as Cameroons (British Cameroons). German administrators were allowed to once again run the plantations of the southwestern coastal area. A British parliamentary publication, "Report on the British Sphere of the Cameroons" (May 1922, p. 62-8), reported that the German plantations there were "as a whole . . . wonderful examples of industry, based on solid scientific knowledge. The natives have been taught discipline and have come to realize what can be achieved by industry. Large numbers who return to their villages take up cocoa or other cultivation on their own account, thus increasing the general prosperity of the country."
