Gods and generals

On the first page he wrote
So here we go:marching out to the battlefield
All prepared to fight
Be by my side, I pray to my God
And on page forty one
No sign of despair I can feel lust and courage
Enemies beware
Here come the kings of insanity

We will die on the glory road to heaven
The brave will live forever
I raise my glass and drink to you
Who will fight 'til final breath with honor
Are we gods or generals? Well I'm not sure
After hours of reading
I can see a change, now the war is a raging beast
Many comrades are now dead

Stay with me lord, you're my shield and my sword
At the end of the book he's another man
Crashed burned luck had turned
Hell is here and now
What have I done and what have I become
March for me soldiers one final time
Walk against the enemies lines with pride
We'll live and we'll die like a man

I don't know
Is the end of the war
I don't know
Will they back for more
So are we so are we
Are we gods and general?
