Hehe, very funny.
My grandfather was in the South Wales Borderers and served with 6th battalion in Burma during WW2, fighting the Japanese. That's how I have my Zulu history.
At the time of the Zulu War it wasn't a Welsh regiment yet and was called the 2nd Warwickshire. There were 2 battalions and only the 2nd battalion were based in Brecon, Wales since the 1870s. Most of the troops were still English though. The 1st battalion were separate from the 2nd battalion and had been abroad for a decade and had been in South Africa for years. The vast majority of 1st battalion were also English. It was the 1st battalion that was wiped out at Isandlwana, with only 1 company of the 2nd battalion. The rest of the 2nd battalion was out with Lord Chelmsford ten miles away looking for the main Zulu impi. There was also one company of 2nd battalion standing guard at Rorke's Drift.
It's a fascinating battle due to the mistakes and wrong doings (in hindsite) that lead to the defeat and at one point the outcome hung in the balance. I completely believe that if the firing line wasn't so far away from the camp and so spread out that the Zulus probably wouldn't have won.
After all closed in proper defences stopped the massed Zulu attacks at Rorke's Drift and Khambula
