I've still got Chickenhawk somewhere- due for a reread soon me thinks.
BTW- the Forgotten Voices/Imperial War Museum books are well worth the read. Its a very different format but the first hand snippets from actual people on the ground give you a totally different perspective.
There are a few instances where people have admitted to shooting their own side to put them out of their misery (with a name/rank and regiment against the person). Plus there was the lad shot for desertion. He'd deserted 4 times previously. Post-shooting, someone mentioned to the Padre that at the battle of Mon this lad had shown outstanding courage- he'd just snapped later on. Why wasn't this brought up at his trial? 'There wasnt enough time'.
Buying Duffy's book today.
