Hi Dave .
I am not aware of your financial status but some of those books can I think be obtained fairly cheaply if you dig around .
My Copy of Zulu Rising hasnt arrived as yet . But from what I have read on the RDVC Forum and here , as well as reviews
in other areas , it would be the one as it is the latest written on Isandlwana and RD and by reports it will become the definitive work on that subject . Of the 5 books you have in your survey , only Brave Men's Blood deals with all the aspects
of the war . It basically comes down to what area of the war you wish to learn about . Contact me by the pm service if
you want me to dig around for you concerning prices of your said books . Sometimes you can get free postage if you are
in the UK , or much cheaper than it is to send here to Australia
. Hope this helps .
