Hister is the Latin name for the Danube river.
Bêtes farouches de faim fleuves tranner;
Plus part du champ encore Hister sera,
En caige de fer le grand sera treisner,
Quand rien enfant de Germain observa.
That's the actual quatrain. A translation:
Beasts mad with hunger will swim across rivers,
Most of the army will be against the Lower Danube.
The great one shall be dragged in an iron cage
When Germania looks over the young Rhine.
