To The Memory of
John Hennen MD FRSE
Inspector of Military Hospitals
And Author of The Principles of Military Surgery
And various other works.
He fell a victim of the Epidemic Fever on
3rd Nov 1828 aged 49 years, and while arduously
Engaged, even to the day preceding his death, in the
Able discharge of the then urgent duties of
Principal Medical Officer
of this garrison.
Is erected by his personal friends, not with a view
of perpetuating his name, for that lives in the more imperishable memorials of his own genius, but as a testimony of regard
For a man whose zeal was indefatigable
And who in the day of calamity sacrificed all
consideration of his own safety for the public zeal.

Following the death of Maitland, Malta and the Ionian Islands reverted to two separate and distinct commands. Sir James McGrigor, Director General Army Medical Services, proposed that the superintendence of both commands should be invested in Hennen: "whose activity, skill, and judgement, may be so much more beneficially exerted in a part of the world which is liable to attack of the most formidable and destructive diseases. Dr Hennen, by having the contract of the Mediterranean arrangements for the troops in both commands, his vigilance will be more usefully directed to the means of securing the whole from the chances of contagion".2
Hennen was to report concurrently to the Marquess of Hastings, the new Governor of Malta, and to the General Officer commanding in the Ionian Islands.
