hi Dave .
I am having a stab here in saying that Cetswayo DIDNT KNOW that he was going to be at war with the
British until his Indunas arrived back from the meeting of 11th Dec , as the British attended his so called
coronation a few years earlier and Shepstone even gave him some sort of crown to mark the occasion .
Cetswayo basically was never going to be the aggressor , he was happy to wait for an invasion and then
act once the british had crossed the river into his land . I think , he thought he could defeat the invading
forces and maybe a truce would be declared . Also he is the king , I wouldnt think he should be going in
person as he may have feared capture or worse !. Throughout history I dont think I can recall any instance
where a reigning monarch has left his own land and travelled to another who had made overtones of war
against them . Hope this helps and makes sense :) .
