Lord CHELSMFORD had recommended defensive formation ("extended lines") in the event of attack before the war.
At, Isandlwana, PULLEINE had followed to the letter instruction of his General.
Or, "PULLEINE was about to defend a large amount of unneccessary real estate".
QUESTION : Could PULLEINE disobey instruction of his General? (i don't know "military protocole" in this century in G.B).
My question is concentrate on the subject: not in the blame of the debacle on CHEMSFORD, PULLEINE or DURNFORD.
