The Battle of the Boarn (West Frisian: Slach oan de Boarn; Dutch: Slag aan de Boorne) was an 8th century battle between the Franks and the Frisians near the mouth of the river Boarn in what is now the Dutch province of Friesland.
In 734 a Frankish army commanded by Majordomo Charles Martel invaded Friesland in a campaign that was part of a series of ongoing wars and skirmishes between the Franks and the Frisians.
The Frisians commanded by King Poppo used boats to land their army and surprise the Franks.
[1] The Franks gained control of the Frisian lands west of the Lauwers estuary and the Frisians became vassals of the Franks apart from the tribes living in East Frisia in present-day Germany.
