I have recently read the book called 'Bloedrivier'. It is also available in English and it is called 'Blood River'. The author is VE d'Assonville and I bought the book at the Voortrekker Monument for R100.00.
The book is about the events that led up to the Battle of Blood River, in Kwazulu Natal, South Africa, on 16 December 1838. The author did not go into an in-depth study, but he simply put the facts on the table from the side of the Voortrekkers and the side of the Zulus. It is very clear to understand what happened before and after the Battle of Bloodriver.
It is easy to read and d'Assonville manages to keep your attention all the way.
