This Charles Martel was practically overlord of Europe north of the Alps from the Pyrenees to Hungary.

German historians were especially ardent in their praise of Charles Martel; Schlegel speaks of this "mighty victory", and tells how "the arm of Charles Martel saved and delivered the Christian nations of the West from the deadly grasp of all-destroying Islam."

Louis Gustave and Charles Strauss said "The victory gained was decisive and final, The torrent of Arab conquest was rolled back and Europe was rescued from the threatened yoke of the Saracens."
