I remember some of this from grade school in the 60's.

To France were returning two Grenadiers.
From Russia where they had been taken.
But when they came to the German frontier,
their brave hearts were badly shaken.
.......missing some lines
France was betrayed and forsaken,
and the Emperor, the Emperor was taken!

........missing the middle.

The Cross of Valor that I won,
place on my heart to cheer me.
And in my hand my trusty gun,
my sword and scabbard near me.

And there I will lie like a Sentry on guard.
Til ........

And then when the Emperor rides over my grave,
and swords like lightening are falling,
and swords like lightening are falling,

Then ready to fight I shall rise from the grave,
the Emperor, the Emperor is calling!
