On 20 May 1940 Edmondson enlisted in the 2/17th Battalion after serving with the 4th Militia Battalion since March 1939. He was promoted to corporal. After training at Ingleburn and Bathurst, his battalion embarked for the Middle East on 19 October 1940 as reinforcements for the 9th Division. After desert training, his division relieved the 6th Australian Division at Marsa Brega in Cyrenaica on 9 March 1941. On 31 March, the German forces under the command of General Erwin Rommel mounted an attack on the Australian and British positions, forcing them to retreat. The 9th Division took up new positions outside the port of Tobruk and on 11 April, the now famous siege began.
Victoria Cross citation
The announcement and accompanying citation for the decoration was published in supplement to the London Gazette on 1 July 1941, reading: An hour later, 200 German infantrymen attacked the post, forcing the Australians to withdraw, and established a bridgehead in the outer defensive line. However, the fierceness of the platoon's defence pressured Rommel into diverting troops from his main attack. The attack failed, with the German tanks being mauled and forced to retreat with heavy casualties. Corporal John Edmondson died of his wounds and is buried in the Tobruk war cemetery. He was the first Australian to receive the Victoria Cross in the war. Edmondson's VC was presented to his mother by the Governor-General on 27 September 1941. In 1969, she presented her son's medals and some of his personal belongings to the Australian War Memorial, where they still are on display.
