France tells Austria war on Piedmont-Sardinia would mean war with France

Austria had issued an emphatic demand that the Kingdom of Piedmont-Sardinia disarm within three days or face attack. Prime Minister Cavour made the Italian reply clear to Vienna on April 26 and at the same time the French minister to Austria told the Austrian foreign minister that France would consider an Austrian strike into Piedmont as an attack upon France. Three days later, Austrian troops began crossing the Ticino and the war was on. (By John Osborne)
