General Sir George White had written that
The Medical Department has been successfully worked by Deputy Surgeon General
Farrell C B, who has conducted his heavy duties with zeal and ability. I would also beg to recall the good services rendered by Surgeon-Major H W A Mackinnon when Principal Medical Officer of the force, in case it may now be possible to grant him the promotion to which he was gazetted, and which was subsequently cancelled.
3 May 1889 Read a paper on the Burma Campaign at the South Indian and Madras Branch of the British Medical Association.
The medical officer's work, said Mackinnon, was incessant; not only was he obliged to accompany columns from posts, and share in the dangers of surprises and ambuscades, but when the troops returned to quarters for a few days his work began again with the attendance on the fresh sick and newly wounded, besides the large hospital list that he had left at his post. Most of them were fairly worn out with diarrhoea, fever and nervous exhaustion. During the campaign no bodies of troops encountered the enemy without medical aid at hand, and in no campaign had the evidence been so fully confirmed of the utility of the doctor on service. His dogged perseverance at the post of duty, his moral support, which was incalculable, his devotion to his charge, heedless of his own complaints, and serving in many instances on reduced pay and small prospects of recognition, tended to exemplify to his small circle that he was a worthy member of a profession second to none. The chief forms of disease were malarial fevers (ague and typhomalarial fever), bowel complaints, hepatic abscess, and, among the Europeans, venereal disorders. Intractable diarrhoea merging into dysentery, generally haemorrhagic, was the greatest trouble. Beri-beri was only met with in the northern stations. Cholera attacked the flotilla on the passage up the river in November, but it became more virulent in December after the troops had been landed at Mandalay. Cholera subsequently visited several of the up-country posts.
