Carlo Orelli (December 23, 1894 – January 22, 2005) was, at age 110, the last surviving Italian World War I veteran who joined the army at the onset of the war. Born in Perugia, although he lived in Rome for most of his life, Orelli came from a military family whose members had served in various Italian conflicts since 1849. A mechanic by trade, Orelli joined the Italian Army in May 1915 and engaged in combat operations in Italy. His recollections were marked by particularly brutal experiences of trench warfare, including the violent deaths of many of his friends. After receiving injuries to his leg, he was pulled from active duty and returned home.
