15 August 1915: Traitors!

Duty 0600 to 1800.  Advance at a stand still.  Desultory firing continues.  Preparing for another advance.
Before proceeding a little may be said of spies.
Two cases I’ll tell you of.  To be exact they were traitors. 
A Sqt Major, in a NZ battery during an attack shortened his fuses and opened fire on our own men, killing quite a number.  Another case a man was discovered signaling to the enemy by means of an electric torch.  Quite a number of spies were caught, but not all by any means.
Everything we intended doing, the enemy always knew of it beforehand and were always prepared.  In preparing for an attack at Lone Pine we were ordered to wear white bands on one of our arms and a white patch on our back so the artillery would be able to distinguish friend from foe.  However when the attack came off, to our amazement the Turks were also wearing white armlets so that shows they were kept well posted as to our movements.
