Reinforcements for Garibaldi's ongoing campaign against Bourbon forces in Sicily left Genoa aboard three American registered ships, the Washington, the Oregon, and the Franklin, all flying the U.S. flag. Around 2,400 men along with their equipment and under the command of Colonel Giacomo Medici stopped at Cagliari, on the Sardinian coast on June 12, 1860 and finally landed safely at Castellamare in Sicily on June 17, 1860.
