Youngest soldier to serve

[anthony]

I realise there is great debate about the youngest soldier to die in the Great War-does anyone have any clear ideas about the youngest soldier to arrive in a theatre of war and in what capacity they served? I know there were many cases of those too young volunteering but what were the extreme cases?

I know the minimum age issue was covered recently for soldiers enlisting, I hope this is slightly more specific.

Thanks for any thoughts you might have,

Anthony
