I used to sing a version of this some 40 years ago which had nothing about fighting. I have no idea where I got it from but others in Edinburgh at that time sang the same version.

Lowlands Low, The

From Dunmore we drifted, Michlemass gone by
Cow hide and wool was our cargo
Twenty young wildies newly fledged tae fly
Sailing for the lowlands low

Chorus:        
The Lowlands Low, The Lowlands Low
Sailing for the Lowlands Low

John White, the skipper, from the town o’ Crook
Here he keeps law for his father
Crew all from Bannow, Fethard and the Hook
Sailing for the Lowlands Low.

Gone from our country, driven by the foe
Proud and yet sad we departed
Green hills behind us, foreign lands before
Sailing for the Lowlands Low

Pray Holy Brendan, help us on our way
Guide and protect us from all danger.
Keep safe our cargo, bring us safely home
Sailing for the Lowlands Low.
