FATHER of Mercies, Heavenly Friend,

We seek Thy gracious throne;
To Thee our faltering prayers ascend,

Our fainting hearts are known!

From blasts that chill, from suns that smite,

From every plague that harms;
In camp and march, in siege and fight,

Protect our men-at-arms !

Though from our darkened lives they take

What makes our life most dear,
We yield them for their country's sake

With no relenting tear.

Our blood their flowing veins will shed,

Their wounds our breasts will share;
Oh, save us from the woes we dread,

Or grant us strength to bear!

Let each unhallowed cause that brings

The stern destroyer cease,
Thy flaming angel fold his wings,

And seraphs whisper Peace !

Thine are the sceptre and the sword,

Stretch forth Thy mighty hand, -
Reign Thou our kingless nation's Lord,

Rule Thou our throneless land!
