Career
He was 26 years old, and a second lieutenant in the 7th Battalion, (Victoria), Australian Imperial Force during the First World War when the following deed took place for which he was awarded the Venture capital. On 8–9 August 1915, at Lone Pine, Gallipoli, Turkey, Symons was in command of a section of newly captured trenches and repelled several counter-attacks with great coolness. An enemy attack on an isolated sap early in the morning resulted in six officers becoming casualties and part of the sap being lost, but Symons retook it, shooting two Turks. The sap was then attacked from three sides and this officer managed, in the face of heavy fire, to build a barricade.
On the enemy setting fire to the head cover, he extinguished it and rebuilt the barricade.
His coolness and determination finally compelled the enemy to withdraw.
