Bonsoir,
Lieutenant H. Hillier, 2/3 NNC was with the Central Column in January 1879.
The 22 January 1879, he was with Lord Chelmsford in the Mangeni.
A letter (undated) written by him to his father was published (in particular) in the Telegraph and Eastern Province Standard, 28 February 1879.
Cheers
Frédéric
