A good quiz but marred at present by several factual inaccuracies. Cameroon has been colonised in parts by France, UK and Germany. Namibia was never under the UK, passing from German ownership to South Africa to the UN. Togo passed from German to French control after WW1.
CardinalSin, this quiz is set at the start of WWI (as per the description). Namibia is listed as under Germany, not the UK. Cameroon was ruled completely by Germany until 1916, after which it was split into French- and British-controlled areas.
