Boileau served with the 29th Foot continuously for more than three years in Jamaica and Barbados. He states that while in the West Indies he "attended altogether but two fatal cases, (mitral valve disease, the sequel of rheumatic fever, and a case of acute haemorrhagic phthisis in a young recruit). We lost not a single man, woman, or child from any endemic or epidemic disease; nor indeed from any zymotic disease whatever, either at Newcastle, Jamaica, or at Barbados, nor did we invalid any, to the best of my recollection.1

13 Aug 1887 On 1 January 1887 War Office Warrant abolished relative rank in the Medical Department of the army. Writing from Ferozepore Punjab, Surgeon–Major Boileau took an opposite stand from the many discontented medical officers of the Army Medical Staff.
"The British Medical Association deserves well of the medical officers of the army for espousing with such promptitude their cause, and prosecuting with such vigour its decision to appeal against the infringement of those rights which seemed to be imperiled by the abolition of relative rank; but the matter is now most satisfactorily settled, and it will be a great mistake for the Association to proceed forwards. I do sincerely hope that no association, college, hospital, or school, will lend its aid to those who are demanding that the medical officers of the army should be called Captains, Colonels, etc. Believe me, Sir, those mischievous agitators are doing a world of harm to the Medical Staff of the Army".

Colonel Boileau was in his usual health in the early part of the week, and on Tuesday drove over to South Wraxall to see his old friend, Mr E Pinckney, with Miss Boileau, reaching home about 5 o'clock. Shortly afterwards he complained of great pain and Dr Pearce was called in. It was evident that Col Boileau was seriously ill.
