Now here is a query I've got about the meaning of one line in the chorus.

Soldiers are we
whose lives are pledged to Ireland;
Some have come
from a land beyond the wave.
Sworn to be free,
No more our ancient sire land
Shall shelter the despot or the slave.
Tonight we man the gap of danger
In Erin's cause, come woe or weal
'Mid cannons' roar and rifles peal,
We'll chant a soldier's song

And the query is this. "Some have come
from a land beyond the wave" - now does this refer to enemies from England, or does it refer to supporters from the Irish diaspora? The words could mean either, but I'd imagine at some time Peadar Kearney would have been likely to indicate what he meant.
