 News of Britain's defeat reached Europe at the end of June 1741 and had immense repercussions.It caused George II of Great Britain, who had been acting as mediator between Frederick the Great of Prussia and Maria Theresa supporting Austria over Prussian seizure of Silesia in December 1740, to withdraw Britain's guarantees of armed support for the Pragmatic Sanction.That encouraged France and Spain, the Bourbon allies, revealed to also be allied with Prussia, to move militarily against a now isolated Austria.
