Re your question on how many were shot at the Drift by Zulus I recall some years ago attending a superb lecture on the action at the Drift delivered by a REME Colonel at the Engineers Museum situated at Brompton Barracks Chatham-UK. Amongst the museum displays were a number of personal items of John Chard.
I seem to recall him stating that most of the casualties from the hospital were stabbed whilst all others received gun-shots which practically aligns with the answer you have already received.
But what stuck in my mind during his gripping lecture was the aftermath or rather the after effects on some of the defenders following their heroic stand. Quite a few as we know fell on hard-times but some suffered what we know now as Post Traumatic Stress Disorder-such as suffering nightmares of wild Zulus charging into their bedrooms at night-one trooper- I believe to be John Fielding-had his hair turn white overnight shortly after the action. But the one I remember most vividly because the Colonel singled me out as the poor fellows name-sake was Robert Jones who blew his own brains out some years later. Tragic stories but the delivery of the lecture was real edge of seat stuff-that colonel really knew his history and knew exactly how to hold his audience spell-bound.
I learned one hell of a lot from that gentlemen especially on how to present a lecture to half-bored students get their interest and retain it throughout their tenure
Sorry guys didn't mean to hi-jack your diodrama
