What will you do when the war is over, tender comrade
When we lay down our weary guns
When we return home to our wives and families
And look into the eyes of our sons
What will you say of the bond we had, tender comrade
Will you say that we were brave
As the shells fell all around us
Or that we wept and cried for our mothers
And cursed our fathers
For forgetting that all men are brothers
