Battle of W.l.n.d.r

The Battle of Wlndr was fought in 934 between the allied Hungarian-Pecheneg army and an army composing of the forces of the Byzantine Empire and First Bulgarian Empire, somewhere in the territory which belonged to the Bulgarian empire, near a large city called W.l.n.d.r (perhaps Belgrade), by the Arab historian and geographer Al-Masudi. The battle resulted in a great victory for the Hungarian-Pecheneg forces, which they followed with a devastating raid up to the walls of Constantinople, forcing the Byzantine Empire to pay them tribute for many years (until 957). Al-Masudi's account of the battle is "one of the greatest descriptions of the nomadic war tactics."
