Interesting reading Littlehand.
Its no suprise, the quotes from Popes diary. The regiments were stood to and then stood down. Many accounts of that, including complaints that breakfsat was served for lunch and it was cold.
There are far and away to many accounts of the troops forming up in there defensive line. Plus the evidence of the graves and findings of the amunition, amunition box bands etc.
The concept of a mass cover up cant really be entertained with any amount of cedibility.
Especially coming from an UNAMED source.
My arguments against this source are: Whilst the grass in January is long and green, the aproaches to the firing lines are uphill. Even sneaking through the grass the troops would be looking down on the Zulu. To get to the plain the Zulu would have to descend from the nqutu plateau. Again impossible without being seen.
As a possible explanation for the "eye witness account". If he was in the right horn, it would be possible for him to have crept along the Manzimyama stream bed then up the slope behind the mountain, over the sadddle and at that point he would have been virtually in the camp area. No tents struck and highly possible caught the odd few soldiers finishing lunch and in shirt sleeves.
I say possible, not probable.
We also need to be aware that for some time after the battle, even up to present day, all sorts of theories, eye witnesses etc have been dragged forward to try and explain the most vexing questions. The news papers of thime were full of different accounts, one even proffesed to have a map drawn by a survivor showing a huge trench into the heart of the camp.
The source is unsubstantiated guys.
