Americans tend to know about the Western Front in WWI, but know nothing about the Eastern Front or the Austria-Italy Front. Due to the movies, people will know a bit about the fight against the Turks via ‘Lawrence of Arabia’ and ‘Gallipoli’.
For fascinating insights into the Austrian military operations, there is a short series of novels by John Biggin. In approximate order they are A Sailor of Austria, The Emperor’s Coloured Coat, and The Two-Headed Eagle. The “hero”, Otto Prohaska, begins the war as commander of a rickety Austrian submarine, manages to sink one of his own navy’s warships, gets a prospective death sentence by transfer to the Austrian flying corps, combines hilarious adventures with some real history lessons about the Balkans and the Hapsburg government. The fact that he survives the war is brought out as he is “discovered” as an old man 100 years old spinning yarns in England.
