Well, this thread seems to be older, but it helped me much to find the Lyrics so I'll post the Chords here, whitch I think, are right. maybe a bit simple :) . I took the first lyricversion, because I know it in this way, too:
       A               fis    D       A
In the bold Galtee mountains so far far away
      A          fis       D            E
I'll tell you a story that happened one day
A             fis    D          E
About a young girl her age was sixteen
       A         fis          D          A      
And she carried a banner white orange and green

Now a young English soldier was passing that way
And he spied the young girl and her banner so gay
He laughed and he joked and got off his machine
Returning to capture white orange and green

You can't have my banner the young girl replied
Till your blood and mine on the bold gaught is lied
For I am a rebel and that's nothing mean
And I'd lay down my life for white orange and green


Well the young English soldier turned white as the snow
Got on his machine and away he did go
For there's no use in fighting a girl of sixteen
Who would die for a banner white orange and green
