The Croatian Grenzers saved the Austrian Empire many times. Kvaternik promised that he would get loyalty of the Grenzers to help Cavour in his war against Austria. Kvaternik knew that the Grenzers were unhappy with the Austrian payments to them after the 1848 Hungarian Revolution. He issued an announcement in Croatian to the Grenzers not to help Austria in their war against the Italians. Kvaternik's announcement had a strong impact as the Grenzer were suffering from low morale while fighting in the Battle of Solferino. Austrians rushed to sign a peace with the French.
