Zulu Dawn is definitely worth watching to find how far bureacracy helped lead to the destruction of the British force and it also goes into details of tactics used by both sides. You will see the differences in leadership between the two engagements. Piffering of rifle ammunition had become so bad that the regimental quartermasters tightly controlled ammunition distribution, even during the battle. The Native Contingent (allied Zulus) were issued only 10 rounds of ammunition, and when a NC soldier drown while fording the Buffalo RIver, the first concern of the QM officer was recovering the rounds of ammo! The ammo boxes were screwed shut and required a special tool, closely controlled by the QM officers

. What killed the British at Isandalawana was a shortage of ammunition on the firing line. The QMs would only issue ammunition to personnel with written requests. Even after the soldiers starting "stealing" the ammunition and dragging the cases to the front line, thry could not open the boxes fast enough. The 24th Foot ran out of ready ammo before they ran out of targets. Remeber the scene in "Zulu" when the soldiers are using a rifle butt to break into a box of ammo.
Great moie and very enlightning concerning Victorian Colonial warfare.
