The mystery of an unknown Australian soldier who went missing in Egypt during the First World War has been solved, ABC reports. Gallipoli veteran Private Edward Attfield was considered a deserter from the Australian Army for over a century until Victorian researcher Martin Elliget helped identify his grave in Egypt. Attfield, whose body was discovered near Giza two years ago, had been fighting with the army’s 5th Battalion before going missing from the area where his body was found. His descendants have chosen to erect a headstone in his honor in the Old Cairo War Cemetery with the inscription: "I once was lost, but now am found."
