 The 'Battle of Dordrecht' can be found among several historians from that era, and it is still suggested by the odd modern historian.This hypothesis is untenable, not only because the sources about the battle in 1018 mention only Vlaardingen and not Dordrecht, but also because Dordrecht in the early 11th century was merely the name of a small river.The name of the place first appeared halfway during the 11th century, and no military stronghold is mentioned anywhere.
