The plebiscite through which inhabitants of Savoy could confirm or reject their planned transfer from Piedmont-Sardinia to France took place on April 22, 1860, with a simple "yes" or "no" the only response on the ballot. The results for Savoy were announced on April 29, 1860 with 130,533 "yes" votes against only 235 "no' votes, confirming the transfer to French control. (By John Osborne)
