The great World War, World War I, proved especially destructive for Pederobba, which was located at the Northern defensive front and faced multiple battles nearby. Following the Battle of Caporetto, Pederobba found itself at the front lines of the Piave and too close to the Grappa and Montello. Various monuments in Pederobba salute the perseverance, and give honor and salute the heroism and courage of the fallen. This includes the French ossuary. The devastation of this war again triggered emigration, now with the Pederobbisi emigrants looking to Oceania as well.
