Enjoyed your review just a few little pointers here,the soldiers didnt run out of bullets as portraid in the movie two things happened,first of all the Martini Henri rifle after firing 15 plus bullets within short peroid of time and the heat was quite likely to jam due to the crimped cartridge that was issued at this time and quality of gun powder that was used hence lull in firing trying to remove faulty cartridge out of the breach,second thing was the huge space between the soldiers they were not side by side as shown in the movie but possibly up to 2-3 metres apart and plenty of them were 1-2kms further on than the main camp itself and the grass would most lilely have been long so when the Zulus launched there full on charge the speed that this was done at plus the above would carve a way through the soldiers lines with not too much trouble.Have walked the battlefild 3-4 times and it is quite a eery place.
There was a point in the Zulu charge where the fire of the British was so intense the charge faultered a chief however rallied the zulus to press on rest is history.
The dead and dying British, Colonial and Native combatants were disembowed and the returning Chelmsford and men had to sleep amongst the dead as they arrived back in the dark.
The little beach you see in the movie where they crossed the Buffalo River with the colours to try and escape is there an absolutely fascinating place.Lt Coghill and Melville didnt die on the beech as shown in the movie but were caught at the top of a hill on the Natal side of the river,how they got up there is a feat in itself as they would have been exhausted and Coghill had twisted his knee earlier chasing a chicken for the pot.They did lose the colours crossing the Buffalo river but were subsequently found downstream a few days later by a Major Black and brought back to Rorkes Drift to great cheers of the second batallion.Check out the book The Washing of The Spears an excellent read.
Hope you find my brief comments helpfull.
