South African War.
Colonel Cholmondeley was appointed to command the Mounted Infantry Section of the C.I.V., to which regiment the London Rifle Brigade contributed 2 officers (Captain C. G. R. Matthey and Lieutenant the Hon. Schomberg K. McDonnell) and 78 other ranks.
When the Volunteer Active Service Companies were raised, 17 members were accepted for service with the Royal Fusiliers, and an additional 76 joined the Imperial Yeomanry and R.A.M.C.
The total death roll of the Regiment was seven.
Colonel Cholmondeley, Lieutenant E. D. Johnson (Imperial Yeomanry), and Colour-Sergeant T. G. Beeton (C.I.V. Infantry) were mentioned in despatches.
