Janette,
Do you also know his regimental number by any chance?
There were a few men of this name in the Boer War:
C Bailey 5th Battalion Royal Fusiliers
C Bailey 3rd Battery Northamptonshire
C Bailey 3rd Battalion East Yorkshire
C Bailey 38th Battery Royal Field Artillery
C Bailey South African Constabulary
C Bailey 4th Battalion Royal Warwickshire Regiment (18th M I)
C Bailey 21st Battalion Imperial Yeomanry
C Bailey 1st Battalion Rifle Brigade
C Bailey Coldstream Guards
C Bailey 2nd Battalion Hampshire
C Bailey 19th Prince of Wales's Own Hussars
C Bailey Barberton Town Guard
C Bailey 2nd Royal Dublin Fusiliers
C Bailey 3rd Battalion Kings Royal Rifle
C Bailey 16th Bengal Lancers Attached To Kitchener's Horse In South Africa
C Bailey 3rd Northhamptonshire
C Bailey 3rd Battalion Kings Royal Rifles
C Bailey 2nd Battalion Grenadier Guards
C Bailey Kitchener's Horse
C Bailey 3rd Battalion Leicestershire
C Bailey Kimberley Light Horse
C Bailey 2nd Battalion Royal Dublin Fusiliers
C Bailey 2nd Imperial Light Horse
C Bailey 3rd Battalion Royal Warwickshire
C Bailey South African Constabulary E Division
C Bailey 2nd Battalion North Staffordshire Regiment
The cap badge is difficult to identify. I thought it may be a grenade on the right collar:
But the left badge looks different again. Something like the Hampshire Regiment?
No doubt it will become obvious when we identify the correct badge.
