In his fourteen letters written in the period of occupation of Bosnia and Herzegovina in 1878, Ivan Mankoč, a native of Trieste, describes the atmosphere in his military unit. This is not merely a description of a military routine but also his personal account of battles in which he fought and of his contact with a completely unknown land. His letters are filled with unease and distress as he finds himself in the firing line and with his attachment to his place of origin, Trieste, where his family (and subsequently he himself) played an important role in the local economy. His letters are eyewitness accounts of events, on which the views of historiography differ greatly from that of the author.V štirinajstih pismih, napisanih v času zasedbe Bosne in Hercegovine leta 1878, opisuje njihov avtor, Tržačan Ivan Mankoč, vzdušje, ki je vladalo v vojaški enoti, v kateri se je takrat bojeval. Ne gre le za opis vojaške rutine, ampak tudi za opis doživljajev v bitkah, v katerih je bil udeležen, oz. v stiku s povsem tujo deželo. Iz pisem prevevata nelagodje in stiska ob preizkušnjah v prvi vojni liniji ter hkra- ti navezanost na izvirno okolje Trst, kjer je njegova družina (in pozneje on sam) odigrala pomembno vlogo v gospodarskem življenju. Pisma so pričevanje o dogodkih, o katerih ima del zgodovinopisja povsem drugačno sodbo od tiste, ki jo je imel njihov avtor
