The Gallipoli campaign is marked by the most extraordinary lack of security. The evacuation is the only period that saw decent security, which is strange because campaigns on the Western Front at the same time saw great lengths taken to maintain secrecy as did the other campaigns in the Middle East taking place simultaneously with Gallipoli, those in Sinai and Mesopotamia.
So are there any other 1914-1916 Allied campaigns that saw such a complete failure to keep a secret or is Gallipoli unique?
