What are possible reasons for the Africans' inability to avoid capture and escape if they are captured?

It all goes back to human psychology. Its fear. Fear of the unknown, fear or what is in their future....Because of this uncertainty, the captured slaves rarely tried to escape. I would liken their situation to the Jews during the Holocaust. Why didn't Jews escape? Why didn't every death camp have a rebellion....the prisoners outnumbered their captors. Its because they didn't realize the fate that awaited them.
