Ähnlich wie beim siebenbürgischen "Vijeltchen" habe ich 2005 auch hier spaßeshalber eine singbare englische Übersetzung versucht, die ich aber zurückziehe zugunsten einer authentisch-englischen Fassung aus dem 19. Jahrhundert. Diese hat das Deutsche Volksliedarchiv Freiburg (DVA) ausgegraben in: The Book of German Songs: from the Sixteenth to the Nineteenth Century. Translated and edited by H. W. Dulcken. London: Ward, Lock, and Tyler 1871, S. 94f. Der vollständigen Originaltext samt Melodie-Varianten kann hier, im Online-Liederlexikon des Deutschen Volksliedarchivs aufgerufen werden!

Die Melodie wurde im 19. Jahrhundert als "The Why and Wherefore" auch in den USA gesungen: Dieser Text sollte in den Nordstaaten Soldaten für den Bürgerkrieg anwerben. So war das Wort "marschieren" eigentlich nicht gemeint!
Eine ähnliche Entwicklung nahm das Lied "O Tannenbaum", indem es als "Maryland, oh Maryland" als Hymne eines US-Bundesstaates Verwendung fand. Zwei von zahllosen Beispielen dafür, wie deutsche Melodien in die nordamerikanische Kultur eingemeindet wurden, auch außerhalb der deutschen Gemeinden. 
Diese Tatsache war ab dem 1. Weltkrieg ein amerikanisches Tabu und wäre heute fast vergessen, gäbe es nicht das Buch von Armin W. Hadamer: Mimetischer Zauber – Die englischsprachige Rezeption deutscher Lieder in den USA 1830-1880. Waxmann 2008.

After the Transsylvanian "Vijeltchen", I first tried to translate this into English by myself. I withdrew it in favor of an authentic English version from the 19th century, made available by the Deutsches Volksliedarchiv Freiburg (DVA) from:  The Book of German Songs: from the Sixteenth to the Nineteenth Century. Translated and edited by H. W. Dulcken. London: Ward, Lock, and Tyler 1871, S. 94f.
This song is great for singing together, so get the tune sheet from the DVA Liederlexikon and try it (or explore the several variants in words and music instead, some even older than 1826)!

The tune was also used in the USA in the 19th century, titled "The Why and Wherefore". Those lyrics were supposed to recruit soldiers in the northern states for the civil war. Which is not what "marschieren" was originally supposed to mean!
The popular German Christmas song "O Tannenbaum" was used in a similar way, becoming the anthem of the US state Maryland. These are just two out of countless examples to show how German tunes were incorporated in American culture, also outside the German communities.
In World War I, this fact was made a taboo subject in America and would almost be forgotten today, if there had not been the book by Armin W. Hadamer: Mimetischer Zauber – Die englischsprachige Rezeption deutscher Lieder in den USA 1830-1880. Waxmann 2008.

THE WHY AND WHEREFORE

"Where, where, where, and where, and where are you bound, young man?

Where, where, where, and where, and where are you bound, young man?"

"I'm off to the war, with the good men and true,

And hadn't you better come along too?

I speak my mind quite freely,

Now ree'ly."

"Why, why, why, and why, and why to the war, young man?

Why, why, why, and why, and why to the war, young man?"

"Did a man ever fight for a holier cause

Than for Freedom and Flag and for Equal Laws?
Just speak your mind quite freely,

Now ree'ly."

"Which, which, which, and which, and which is the Flag of the Free?

Which, which, which, and which, and which is the Flag of the Free?"

"Oh, Washington's Flag, with the stripes and the stars,

Will you give such a name to the thing with the bars?

I speak my mind quite freely,

Now ree'ly."

"Who, who, who, and who, and who goes with you to the war?

Who, who, who, and who, and who goes with you to the war?"

"Ten thousand brave lads, and if they should stay here

The girls would cry shame, and they'd volunteer!

They speak their mind quite freely,

Now ree'ly."

"When, when, when, and when, and when do you mean to come back?

When, when, when, and when, and when do you mean to come back?"

"When Rebellion is crushed, and the Union restored,

And Freedom is safe—yes, then, please the Lord!

I speak my mind quite freely,

Now ree'ly."

"What, what, what, and what, and what will you gain by that?

What, what, what, and what, and what will you gain by that?"

"Oh I've gained enough, whatever the cost,

If a Free Land, the hope of the world, isn't lost.

I speak my mind quite freely,

Now ree'ly."
