There have been, in fact, two Battles of Montebello. One in 1800, when Napoleon’s army defeated Austrian forces, and one in 1859, during the Second Italian War of Independence, when Piedmontese cavalry and French infantry defeated, again, Austrian forces. Neither was especially bloody, but this second one was instrumental in the process of Italian unification. You’d think that ‘Montebello’ meant ‘beautiful mountain’, but it doesn’t. The second part actually derives from the Latin bellum, meaning ‘war’. (The same is true of Alberobello in Puglia.)
