717 Battle of Vincy between Charles Martel and
Ragenfrid who returned defeated to Neustria.
Instead of following the army immediately, Charles again used tactics he would use all
his remaining life, in a career of absolute success. He took time to rally more
men and prepare, before descending in full force. He chose where to provoke
them to battle, and, at a place and time of his choosing, in Spring 717,
Charles eventually followed them and dealt them a serious blow at Vincy on 21
March. He chased the fleeing king and mayor to Paris.
