Riverine warfare in Africa...those words are enough to bring to mind the names of great rivers like the Zaire, the Zambezi, and the Maputo. Now couple that with images of Conrad's Heart of Darkness and distant jungle battles, and you have a great book. Portugal was the first colonial power to arrive in Africa and the last to leave. Being a small country with limited resources, their longevity can be attributed to their creativity, adaptablity, and affinity for their colonial home.
