The more important battle in the history of the Arab conquests was Codavonga. As the surviving Visigothic princes and the Basques were able to hold on after beating the Arabs in the small unit action at Codavonga, the later Moorish realms didn't have any natural boundries to serve as defences (the Pyrennes would have served as a great natural defence, but the Muslims never got that far). As a result of the defeat at Codavonga, the Muslim rulers of Al-Andulsus were on the back foot until the fall of Granada in 1492, with only the shifting alliances of the Reconquista buying them enough time to create a culture that is a byword for learning and religious cooperation to this day.

Germany would have been better under the rule of the Ottoman Sultan than under the motely collection of princes it got stuck with by the end of the 30 Years War.
