Hello Malcolm
I can see your dilemma, Watts Memoriam has your 2 men has being KIA on the 24th of February 1900. Corporal Seymour 4261 Tugela Heights/ Harts Hill, interred at Tugela Onderbroek monument number U19A.
Private J White 4871 wounded on the 23rd February 1900 ,died of wounds on the 24th February 1900. Interred at Tugela/ Harts Hollow monument number 29A.
Interestingly, having checked the Natal Field Force roll , both soldiers were recorded as being killed in action on the 27th of February 1900.
Medal rolls also reflected the 27th for White and what looks to be the 28th for Seymour.
Looking at the other Dublin Fusiliers casualties pertaining to Harts Hill action, both dates of the 24th and 27th of February 1900 are recorded with KIA and wounded men.
Sometimes the transcription of dates from various casualty records contained anomalies.
My apologies for not being exact , perhaps a fellow forum member may be able to help nail the correct dates?
Dave......
You only live once, but if you do it right, once is enough.
Best regards,
