Can a recruit change his eye colour?

22 Battalion, newly arrived from Egypt, going into line at the southern part of Lone Pine, 6 September 1915  AWM A00847

When Davey joined the 22 Inf Bn in 1915 his eyes were blue, but when he re-enlisted in 1917 after being sent home wounded, his eyes were brown.   One of life's little mysteries.    Rod Martin tells this and other stories about the life and death of Private Davey of Moonee Ponds.  Once wasn't enough for Alman Davey - he enlisted twice, but wasn't so lucky the second time.   Read his story here.
