That's the whole point of the battle ~ the Moslem governor of Spain (which has, of course, had various names in various languages) led military forces into France to assist Moslem converts/settlers who were under attack by Frankish bandits.
He got killed.
End of story.
It was a really big event to the bandits. Not such a big event to everybody else.
I thought you were referring to the founder of the Andalusian Ummayads, Abd-al-Rahman, not the defeated invasion general, Abd-al-Rahman Al Ghafiqi.

BS. He wasn't rescuing wayward converts. He was invading with over 60,000 men, following the same tactics that they had used to expand across North Africa and Visigoth Iberia. Two years before, the Muslims had sacked and burned their way through Aquitane, Gascony and Bordeaux.
Martel wasn't leading "bandits", either. He was a King in all but name of most of Western Europe, and had specifically trained his army to fight Muslim cavalry, anticipating more expansion. If the Ummayads hadn't got their asses kicked in a civil war back in Syria, they probably would have tried again.
