 The Peace of Prague led to rumours of a proposed Austro-Spanish offensive in the Netherlands, leading Louis XIII and Richelieu to decide on direct intervention.In early 1635, they signed an agreement with Bernard of Saxe-Weimar to provide 16,000 troops for a campaign in Alsace and the Rhineland, an anti-Spain alliance with the Dutch Republic, and the Treaty of Compiègne with Sweden.In May, a French army of 27,000 advanced into the Spanish Netherlands, defeating a smaller Spanish force at Les Avins, before linking up with the Dutch.
