They Shall Not Win by Ella Wheeler Wilcox

Whatever the strength of our foes is now,
Whatever it may have been,
This is our slogan, and this our vow –
They shall not win, they shall not win.

Though out of the darkness they call the aid
Of the evil forces of Sin,
We utter our slogan unafraid –
They shall not win, they shall not win.

We know we are right, and know they are wrong,
So to God above and within –
We make our vow and we sing our song
They shall not win, they shall not win.

It rises over the shriek of shell,
And over the cannons’ din:
Our slogan shall scatter the hosts of Hell –
They shall not win, they shall not win.
