Biography contributed by Robert Devlin

"...1940 Private Oswald Victor Mildwater, 59th Battalion. A student from Hoxton Park, NSW prior to enlistment, Pte Mildwater embarked with the 3rd Reinforcements from Melbourne on HMAT Port Lincoln on 4 May 1916. Later transferring to the 60th Battalion, he was allotted the regimental number 1940B. Following his promotion to Corporal he was wounded in action on two separate occasions and evacuated to England. Due to the severity of his latter wound he returned to Australia on 15 September 1918 and was medically discharged. He later went on to serve in the RAAF during the Second World War with the rank of Squadron Leader with the Director of Technical Services..." - SOURCE (www.awm.gov.au)


Oswald Victor Mildwater was born on 6 June 1897 at Woollahra New South Wales. His parents were Alfred Robert Mildwater, a carpenter and Clara Maud, who worked in the home. Mildwater completed his primary education at Hoxton Park Public School, and completed his secondary education at Sydney Technical High School.[i] He was one of four children; he had two sisters Lily Violet (1900) and Mary Irene (1904) and one brother Ernest G (1902). Mildwater was not married before World War I started. [ii]

Mildwater enlisted at the Casula barracks on 29 January 1916 at age 18 as a Private[1]. He embarked from Melbourne, Victoria on 4 May 1916[2] on board the HMAT A17 Port Lincoln heading towards England via Suez, Egypt and France. Mildwater arrived in Egypt and completed training with the 60th Battalion. Mildwater undertook several training exercises such as shooting and physical fitness. He later departed from Egypt on 3 August 1916 and disembarked in Marseille, France on 8 August 1916. On 11 November 1916, Mildwater battled in France to reinforce the 57th battalion. While he was a part of the 57th Battalion he fought in the Battle of Fromelles which dated from 19 July 1916 to 20 July 1916.[iii] The main objective of this battle was to distract and avert German troops further away from the Somme however this objective was not met as the Germans had better defensive strategies such as placing machine guns along their front which gave them an advantage. He later re-joined the 60th Battalion on 1 December 1916, and was promoted to Corporal on 19 February 1917. [iv]He was amalgamated to the 60th Battalion and was part of the Second Battle of Bullecourt which dated from 3 May 1917 to 17 May 1917. This battle aimed to fortify the village of Bullecourt. The Allied forces penetrated through German lines trying to encircle the German troops which forced them to withdraw out of Bullecourt.  

During his time in World War I, Mildwater suffered numerous illnesses possibly from lack of sanitation and the harsh conditions of life as a solider. On 30 December 1916, he was admitted to a hospital in Rouen, France as a result of mumps. The severity of the mumps meant that he did not re-join the forces until the 3 February 1917 which was more than one month after. Additionally, on the 23 September 1917 he was admitted to hospital in Perham Downs as a result of severe inflammation in the knee.[v]

Mildwater was promoted to Corporal and was severely injured on two separate occasions. On 12 May 1917, Mildwater sustained a shell wound to his left knee at Bullecourt. After this first injury Mildwater was recorded committing the crime of neglect of duty. As a result, he was severely reprimanded by the commander of the 60th Battalion on the 4 April 1918.[vi] Mildwater also suffered a bullet wound and compound fracture on his left arm on 17 June 1918 at Villers-Bretonneux on the Western Front, one of the main theatres of war. After he was injured he was sent to Bristol, England to the Beautfort War Hospital. He was later transferred from that hospital to the 3rd Auxiliary Hospital in Dartford England until 3 July 1918.[vii]

The severity of his wound meant that he was evacuated to multiple hospitals in both France and England. This led to his return to Australia on 19 November 1918 on the HMAT Awara. He was later discharged from a hospital in Randwick, Sydney on the 24  December. In November 1918, Liverpool Railway Station was decorated in his honour for his return home. Additionally, Mildwater was awarded the British War Medal and Victory Medal. The British War Medal was awarded to soldiers that entered the war during specific times, whilst the Victory Medal was awarded to individuals that served between 5 August 1914 and 11 November 1918. [viii]

Upon return and discharge in Australia, Mildwater enrolled in tertiary education at The University of Sydney. He completed his Bachelor of Mechanical and Electrical Engineering graduating on 17 May 1923.[ix] Mildwater was appointed Engineering Assistant in the Engineering Section of NSW Department of Works and Local Government in 1924. In the same year Mildwater married Dorothy Patricia Rooney-Wall in Newcastle.

During the Second World War Mildwater served in the Roswell Army Air Field (RAAF) with the rank of Squadron leader with the Director of Technical Services. He was part of the 59th Battalion. In 1941 Mildwater divorced his wife[3]. He later remarried Bertha Lucas in 1946 in Kingswood. Mildwater was appointed engineer in the Architectural Section of the NSW Department of Public Works on 27 January 1960. Mildwater died on the 3 May 1968 at St Leonards.
