How were African colonies affected by world war 1, both during the war and after

The most impressive monument for African victims of the World War I (1914-1918) is not to be found in Africa but in France. At the battle of Delville, one of the engagements of the Battle of the Somme in 1916, the South African 1st Infantry Brigade sustained heavy casualties. John Del Monde knows the site well. He is a member of the board of the South African Legion veterans' association. Together with partner associations from other Commonwealth member states, he has made it his life's work to keep alive the memory of all those who fought for the British monarchy. To mark the 100th anniversary of the start of World War I, ceremonies are being held in South Africa and Namibia and a new monument unveiled in Flanders, Del Monde told DW. Some 10,000 South African soldiers died in Belgium, France, Pakistan, North Africa and former German colonies in Africa. The South African Legion is one of the few bodies in Africa which honors their sacrifice. There is limited knowledge about WWI among the black African population, Del Monde says. During the conflict, some 2 million people from across Africa were actively involved in the military confrontations, as soldiers or bearers, in Europe and in Africa. At the start of the war, some Africans volunteered to take part, encouraged by the prospect of a modest income. From 1915, the Europeans began conscripting thousands of African men. The French alone sent 450,000 African soldiers from their colonies in West and North Africa to fight against Germany on the frontline in Europe.

One million killed in East Africa . When war broke out in Europe in 1914, English and French troops prepared to seize the four German colonies in Africa (German East Africa, German South-West Africa, Togoland and Cameroon). Fighting was particularly brutal in German East Africa where German General Lettow-Vorbeck adopted a guerilla strategy, drawing more and more areas into the war. More than 200,000 bearers transported weapons, ammunition and food for the troops. The myth of the "faithful Askari" (the Swahili word for 'soldier') still exists today in German history books. In reality these men had been torn from their roots and were looked down on by local populations. Back home, they were missed in the fields. Harvests suffered or were plundered and destroyed by troops passing through to ensure there would be no food left for their pursuers.

answer: the time zones used to be whatever the local authority wanted them to be. one town might have 6am whenever the sun came up and another town had 6am 10 minutes later.  

the trains had a hard time when their orders said to be at a certain point at 6am.  

6am, but who's 6am.  

the railroads got together and set the time zones more or less along the longitude lines across the country.
