Wittekind, leader of the Saxon struggle against Charlemagne; annihilated the Frankish army in 783, in retaliation for which Charlemagne executed 4500 Saxons he had taken prisoners, which roused the entire Saxon people to arms, and led to a drawn battle at Detmold, upon which Wittekind accepted baptism, and was promoted to a dukedom by the Frankish king; he fell in battle with Gerold, a Swabian duke, in 807.
