Question: How many german forces were in these regions? Passage 1:During World War I (1914–18) an expanded Force Publique served against German colonial forces in the Camerouns and German East Africa (Tanzania, Rwanda, Burundi), as part of the East African Campaign. The Force Publique performed well on the battlefield, winning the respect of their British and Portuguese allies, as well as that of their German opponents. 1916 onwards, the Force Publique grew to reach a strength of three mobile Groupes (brigades), Kivu, Ruzizi, and Tanganyika, comprising a total of 15 battalions, from the static garrison and police force of 1914. However, it did take until late 1915 for the Force Publique to finish preparations for a large scale offensive on the German colony of German East Africa. The allied powers, the British Empire and Belgium launched a coordinated attack on the German colony, by 1916 the Belgian commander of the Force Publique, Lieutenant-General Charles Tombeur, had assembled an army of 15,000 men supported by local bearers and advanced to Kigali. Kigali was taken by 6 May 1916. The German army stationed in Burundi was forced to retreat by the numerical superiority of the Belgian army and by 17 June 1916, Burundi and Rwanda were occupied. The Force Publique and the British Lake Force then started a thrust to capture Tabora, an administrative centre of central German East Africa. The army went on to take Tabora on 19 September after heavy fighting. At the time of the Battle of Tabora in September 1916 about 25,000 men were under arms, during the war their actions were supported by more than 260,000 local bearers. In 1916 Charles Tombeur was made Military Governor of the Belgian Occupied East African Territories. After the Mahenge Offensive and the capture of Mahenge in 1917, the Belgian Congolese army controlled roughly one-third of German East Africa. After the war, as outlined in the Treaty of Versailles, Germany was forced to cede "control" of the Western section of the former German East Africa to Belgium. On 20 October 1924, Ruanda-Urundi (1924–1945), which consisted of modern-day Rwanda and Burundi, became a Belgian League of Nations mandate territory, with Usumbura as its capital.
 Passage 2:His father, John F. Link Sr., was also a film editor, and was also nominated for an Academy Award: for the 1943 film, For Whom the Bell Tolls. Link was one of several assistant editors on the film. That same year he was the sole editor on the documentary, Footprints on the Moon. Both the film and the documentary have his credit as John F. Link Jr., making attribution easy. His next project was another documentary, Say Goodbye in 1971, which was nominated for an Academy Award for Best Documentary (Feature). During the 1970s he worked in both television and film. Notable films he edited during this period include: The King of Marvin Gardens]] (1972), starring Jack Nicholson, Bruce Dern, and Ellen Burstyn; the 1973 cult classic Electra Glide in Blue (which he co-edited with two others); Race with the Devil (1975), starring Peter Fonda and Warren Oates; and the 1976 Jeff Bridges' comedy-drama film, Stay Hungry, which also starred Sally Field and Arnold Schwarzenegger.
