Theodor Gribovski from Krems left for the front at the outbreak of the First World War as a cadet with the Imperial-Royal Field Canon Regiment No. 37 and was promoted within a few months to lieutenant and eventually to first lieutenant. In summer 1916 he was involved in the Russian Army’s hitherto greatest offensive in Bukovina, the so-called Brussilov Offensive. In a forces letter, copied later by his mother Hermine and compiled together with other messages into a “diary”, he describes in patriotic epithets the action of the Imperial-Royal Army against the “Asiatic Beast”, whose victory, in his opinion, would not be long-term. Theodor Gribovski was designated retired captain at the end of the war.
