He served with distinction for the 22nd Native Infantry in India and was awarded the Army of India medal with rare clasps including those for the Battle of Deig and Capture of Deig. He was shot in the head during the Siege of Bhurtpore, but survived the battle.
Time in Java
Following his service in India, Davy joined and actively participated as a Captain in the 4th Bengal Volunteer Battalion during the invasion of Java and overthrow of the Dutch occupiers. He had knowledge of the Malay/Javanese languages and worked at the request of Sir Samuel Gibbs as his Secretary and also an interpreter and translator for Sir Stamford Raffles. Duties included being sent as part of an envoy to the Yogyakarta sultanate prior to the takeover of that city. Following the success of the British he was given the title of Acting Deputy Commissioner and served as Resident, Treasurer and Magistrate in Surabaya, Bangkalan and Cirebon. He was notorious in Cirebon for levying a heavy land rent. Davy translated and donated documents from this period to the Bodleian library. He left Java in 1815.
Upon his retirement from the military, Davy returned to the UK and built a house near Bridgend named "Sarn Fawr" and was involved in early development of railways in this area.
In 1841 Davy purchased land from the New Zealand Company and emigrated to New Plymouth, New Zealand. Whilst in New Plymouth, Davy established a farm called "Glenavon" and built several buildings including a retail store and the first brewery, malt house and public house in the township. A beer brewed by Captain Davy known as "Davy's Stout" is mentioned in a "Song for Taranaki" written in 1844. Artifacts from the brewing enterprise, including some copper jugs, are retained in the Puke Ariki museum in New Plymouth. Davy then returned to the UK to attend to his daughters education, leaving his two eldest sons Charles and Edwin to manage affairs in New Plymouth.
