Hello Evan,
I just wanted to add that the french version was published by Georges Moustaki and has its entry on LT here:
https://lyricstranslate.com/en/georges-moustaki-la-marche-de-sacco-et-va...
And you have a little mistake in your translation to english, the last verse would be:
but through this you will triumph
:)
in italics the french version (written by Georges Moustaki) that you can hear by Nana Mouskouri below. It's translation:
Right now Nicola and Bart
you are sleeping deep in our hearts
you were all alone in death
but through this you triumphed
