Invasion in 1914 At the outbreak of war in Europe in early August 1914, the German colonial administration in Kamerun attempted to offer neutrality with Britain and France in accordance with Articles 10 and 11 of the
Berlin Act of 1885. However this was rejected by the Allies. The French were eager to regain the land ceded to Germany in the
Treaty of Fez in 1911. The first Allied expeditions into the colony on 6 August 1914 were from the east conducted by French troops from
French Equatorial Africa under General
Joseph Gaudérique Aymerich. This region was mostly marshland, undeveloped, and was initially not heavily contested by Germans. By 25 August 1914, British forces in present-day Nigeria had moved into Kamerun from three different points. They pushed into the colony towards Mara in the far north, towards Garua in the centre, and towards Nsanakang in the south. British forces moving towards Garua under the command of Colonel MacLear were ordered to push to the German border post at Tepe near Garua. The first engagement between British and German troops in the campaign took place at the
Battle of Tepe, eventually resulting in German withdrawal. In the far north British forces attempted to take the German fort at Mora but initially failed. This resulted in a long siege of German positions which would last until the end of the campaign. British forces in the south attacking Nsanakang were defeated and almost completely destroyed by German counter-attacks at the
Battle of Nsanakong. MacLear then pushed his forces further inland towards the German stronghold of Garua but was repulsed in the
First Battle of Garua on 31 August.
Naval operations In September 1914, the Germans had mined the Kamerun or
Wouri estuary and scuttled naval vessels there to protect
Douala, the colony's largest city and commercial centre. British and French naval vessels bombarded towns on the coast and by late September had cleared mines and conducted amphibious landings in order to isolate Douala. On 27 September, the city surrendered to Brigadier General
Charles Macpherson Dobell, commander of the combined Allied force. The occupation of the entire coast soon followed as the French captured more of the territories to the south-east in an amphibious operation at the
Battle of Ukoko.
War in 1915 By 1915, the majority of German forces, except for those holding out at the strongholds of Mora and Garua had withdrawn to the mountainous interior of the colony surrounding the new capital at
Jaunde. In the spring of that year German forces were still able to significantly stall or repulse assaults by Allied forces. A German force under the command of Captain von Crailsheim from Garua even went on the offensive, engaging the British during a failed raid into Nigeria at the
Battle of Gurin. This surprisingly daring incursion into British territory prompted General Frederick Hugh Cunliffe to launch another attempt at taking the German fortresses at Garua at the
Second Battle of Garua in June, resulting in a British victory. This action freed Allied units in northern Kamerun to push further into the interior of the colony. Approximately 5,400 soldiers from the Indian 5th Light Infantry Division arrived in November 1915 to support allied offensives deeper into Kamerun. This push resulted in the Allied victory at the
Battle of Ngaundere on 29 June. Cunliffe's advance south to Jaunde, however, was stalled by heavy rains, and his force instead participated in the continuing
Siege of Mora. When the weather improved, British forces under Cunliffe moved further south, capturing a German fort at the
Battle of Banjo in November and occupying a number of other towns by the end of the year. By December, the forces of Cunliffe and Dobell were in contact and ready to conduct an assault of Jaunde. In this year most of
Neukamerun was occupied by Belgian and French troops, who also began to prepare for an assault on Jaunde.
Surrender in 1916 In early 1916, the German commander, Carl Zimmermann came to the conclusion that the campaign was lost. With Allied forces pressing in on Jaunde from all sides and German resistance faltering, he ordered all remaining German units and civilians to escape to the neutral
Spanish colony of
Rio Muni. By mid-February of that year the last German garrison at Mora surrendered, ending the
Siege of Mora. German soldiers and civilians which had escaped to Spanish Guinea were treated amicably by the Spanish, who had only 180 militiamen in
Río Muni and were unable to forcibly intern them. Most native Cameroonians remained in Muni but the Germans eventually moved to
Fernando Po; some were eventually transported by Spain to the neutral
Netherlands (from where they could reach home) before the war was over. Many Cameroonians, including numerous chiefs of the
Beti people, moved to Madrid, where they lived as visiting nobility on German funds. ==Atrocities==
