I found the follow in an online ebook (Coomassie and Magdala : the story of two British campaigns in Africa):
Sir Grarnet Wolseley has paid the penalty which Africa inflicts on the European who treads her shores. His audacity
in braving the hot sun at mid-day has been punished by an attack of fever. Others are sufferers as well. Two officers only, however, have been buried since my arrival — Eardley Wilmot, already mentioned, and Harry Mount, of the Control Department, who died of dysentery. Colonel M'Neill, Chief of Staff, has been invalided home ; Captains Brackenbury and Charteris have been on the sick list; Major Baker, Acting-Adjutant-Greneral, vice M'Neill, has suffered from dysentery
I'm assuming that Harry Mount should read Harrymount, because Eardley Wilmot, who served in the Royal Artillery, is also shown on the Ashanti medal roll as 'Dead'.
