This song is about the Falklands War, which was going on when Dire Straits lead singer Mark Knopfler wrote the song. The Falklands War was a conflict between Argentina and England over islands off the coast of Argentina that each country claims rights to. The islands are British territories, but in 1982 Argentina tried to reclaim one of the islands. Britain reclaimed their territories, but lost 258 soldiers in the conflict. The song was inspired by Knopfler's father remarking "We shouldn't be making war on our brothers in arms."
These mist covered mountains
Are a home now for me
But my home is the lowlands
And always will be
Some day you'll return to
Your valleys and your farms
And you'll no longer burn
To be brothers in arm
Through these fields of destruction
Baptism of fire
I've watched all your suffering
As the battles raged higher
And though they did hurt me so bad
In the fear and alarm
You did not desert me
My brothers in arms
