Who does the narrator dislike in this novel and what have they been doing?

The narrator disliked the actions of both the Fench and the English for their interference in the land of the Native Americans.

The facilities which nature had there offered to the march of the combatants were too obvious to be neglected. The lengthened sheet of the Champlain stretched from the frontiers of Canada, deep within the borders of the neighboring province of New York, forming a natural passage across half the distance that the French were compelled to master in order to strike their enemies. Near its southern termination, it received the contributions of another lake, whose waters were so limpid as to have been exclusively selected by the Jesuit missionaries to perform the typical purification of baptism, and to obtain for it the title of lake "du Saint Sacrement." The less zealous English thought they conferred a sufficient honor on its unsullied fountains, when they bestowed the name of their reigning prince, the second of the house of Hanover. The two united to rob the untutored possessors of its wooded scenery of their native right to perpetuate its original appellation of "Horican."
