10 June 1873,
There was a leaflet that talked about leaving Navarra to be part of Spain during the Carlist War. Viva Navarra broadcast under the signing of El aldeano navarro! The booklet called "Yanguas" was one. He talked about carlism as something that happened in time, although he doesn't want its failure. In the text it attacks Castile and its army and talks about uniting Navarre with France.
