Frank Hills known as ‘Trooper’ was an officer and a gentleman in the truest sense of the word. A Boer War and World War One veteran twice wounded at Gallipoli and again in the Somme in France. Trooper rose through the military ranks to Regimental Sergeant Major, the highest ranked non- commissioned officer in the Australian Army. Trooper survived the war to become a prison officer and eventually would become involved in one of the greatest conspiracies to kill in Boggo Road Gaol History. The infamous Cyanide Plot.
