Looks like it's the last verse that's missing from gnomad's English translation: it's not all a direct translation anyway: the French version is about the swallows returning (presumably after the winter)and doesn't mention either the dawn or the morn!

Below, my rather literal translation of verse 3: it needs to tweaked a bit to make it scan better, and perhaps re-phrased a bit too!

It is a time in your life
When every dream must finish,
A period when the soul, collected in,
Has need to remember,
When my cooled muse
Has finished its songs of love
I will see again my Normandy,
It is the country where I was born
