It would have been interessting if Sam Mangwana talked about his time in Brazzaville as soldier with other Angolan people who came from Kinshsa to prepare the attack against the Portugese people on 4 January 1961 in Angola which went totally wrong . I can understand why he don't want to talk about it. I had an Angolan friend who used to fight for FLNA and tried to get with them the power in Luanda along with Zairian soldiers in 1975 which also went wrong. But he never talks about that because of traumatic memories.
