On this day in 1916, Allied forces complete their conquest of the Cameroons, a German protectorate on the coast of western Africa.
Drawn by the rich trade of slaves, ivory and rubber established in the 17th century, German and British settlers began to explore inland Africa beginning around 1860. In 1884, Germany established a protectorate over the Douala region; Britain did not dispute the claim. By the early 20th century, Germany had built roads, begun the construction of a railroad and cultivated large plantations of cacao, palm and rubber in the region. They had also built a city, Douala, on the Atlantic coast, which by 1914 served as the principal port and wireless station in the Cameroons.
The British launched their campaign in the German Cameroons in late summer 1914, just after the outbreak of World War I; it would last 18 months. The British failed to anticipate the German strategy: knowing the formidable strength of the British navy, the Germans decided not to concentrate on defending the coast, but instead to withdraw inland and use the rough interior of the continent to fortify their resistance. Thus, although British forces earned quick successes—they secured Douala by September 27, 1914, without firing a shot—they were not able to fully take control of the Cameroons until the following February.
The West African Frontier Force, fully committed in the Cameroons until March 1916, was one of two sets of "local" troops that the British turned to in Africa; the other was the South African Defense Force, which concentrated on the campaign in German Southwest Africa (now Namibia). African soldiers in World War I were generally compelled to enlist or were mercenaries. Some served on both sides during the war.
In 1919, during the Versailles peace conference, Britain was given a mandate over one-fifth of the former German Cameroons; the rest was assigned to France. A mandate was a commission granted by the newly created League of Nations allowing member states of the League to establish their own governments in former German territories. Both the British and French Cameroons were made trust territories of the United Nations after World War II. The French Cameroons gained their independence in 1960 as the Republic of Cameroon. The following year, after a U.N. plebiscite was conducted in the British Cameroons, the southern half of the territory joined the Republic of Cameroon, while the Northern Cameroons became part of Nigeria.
