Petition Pardon for WW1 Soldiers

After reading many books on the First World War and the conditions they fought in I write for this petition to be discussed in Parliament.
With the First World War fast approaching 100 years since it's start isn't it about time that the Soldiers who were accused of desertion, when really they were only suffering from shell shock and associated illnesses are given a full pardon by this government. It has been proved that most of these soldiers were suffering from post traumatic stress disorder which at the time had no treatment, and don't forget most of these so called deserters were shot at dawn, orders given my General's who had never even seen the front line or suffered the trauma of fighting on the front line. And the most important thing to remember they volunteered and died for THIER country and for US. Please sign this petition and ask all your friends to do the same, it's your ancestors right's your fighting for now.
