That would never have done with the 24th at Rorkes Drift!
Interestingly, the majority of the 24th Regiment of foot who fought in the Zulu Wars came from Warwickshire. The Regiment had moved from Warwick into barracks at Brecon only a year or so before they shipped out to South Africa. Only about 10% of the troops were Welsh. They became the "South Wales Borderers" in the 1881 re-organisation. The Regimental March was "The Warwickshire Lad", and they certainly would not have sung "Men of Harlech" during the battle of Rorkes Drift.
