motivation strikes briefly but ends quick

So now i preach, to the morning sun
There's a land to be conquered, there's a battle to be won
Up a mountain, down the road, so we carry on
Until the threat is vanquished and it is long gone
Dust kicked under hooves in a steady clip-clop beat
Longing with  thirst, going mad in the heat
Laments ring around of where you'd rather be
Kicked up in a mansion, sipping cocktail martinis
Our opponents ferocious, unrelenting like a rising tide
The cowardly beast in me screams to run and hide
Their toothy, shameless grins promise a painful demise
And hateful fire seems to burn in the embers of their eyes
But we cannot give up now, now that we've come so far
High up in the night glows the watchful morning star
And eyes gaze down upon the troops, marching oh so similar
Do they know what they truly want, do we know what we truly are?
The whetstone flicks as it grinds out a steady tune
Well-honed blades shine in the silvery light of the moon
Axes accurate and deadly, from a great oak they were hewn
Our military faction will enter the bloodbath quite soon
My wife and children will grieve upon my timely death
But for my pride and our honor, I'll gladly breathe my last breath
Will I rise to paradise with the angels, or be dragged deep underneath?
Our commander calls for battle, so I'll have to wait and see
Froth flicks from the crazed mouths of calvary horses
Men are mutilated by other men, what a clash of forces
And the blood in my veins pumps through the heart as it courses
Voices call frightfully, desperately, fearfully for reinforcements
But many are too late, and their recipients are long gone
Souls snatched by the grim reaper in a rite of automaton
The star from before shines sadly, there is nothing it can act upon
I struggle in warfare, tiredly, and from my lungs comes this song
