 Passage 2:The film begins with a narrated map showing the Confederate Army of Northern Virginia, commanded by Robert E. Lee, crossing the Potomac River to invade the North in June 1863, marching across Maryland and into Pennsylvania. On June 30, Confederate spy Henry Thomas Harrison reports to Lt. Gen. James Longstreet, commander of the First Corps, that the Union Army of the Potomac is moving in their direction, and that Union commander Joseph Hooker has been replaced by George Meade. Longstreet reports the information to General Lee, who is concerned that the army is moving "on the word of an actor", as opposed to that of his cavalry chief, J. E. B. Stuart. Nonetheless, Lee orders the army to concentrate near the town of Gettysburg. At the Union encampments near Union Mills, Maryland, Col. Joshua Lawrence Chamberlain of the 20th Maine is ordered to take in 120 men from the disbanded 2nd Maine who had resigned in protest, with permission to shoot any man who refuses to fight. Chamberlain speaks to the men, and is able to persuade all but six to take up arms.
 Passage 3:Travelogue writer, brother of more noted Ivan, the writer of the well-known epic Smrt Smail-age Čengića. He attended a German school in his native town, where he was trained to become a blacksmith. Often he indulged into travels (Montenegro, Serbia), and exceptionally in a few occasions to Bosnia. In 1841 he was back to Novi, practicing his craft and agriculture, but also engaging in literature and cultural issues in general. In 1847 he ended up in Vienna, in 1848 again in Bosnia (in Sarajevo, at the court of Fazli-paša Šerifija). At the end of 1848, in a letter addressed to his brothers he says: "I don't know when I shall return home, for I have been, I'm afraid, created for this country. Turks are very fond of me for my prudence, they say, and rayah grows ever more trust in me, and therefrom there is no other outcome but mitre on the head or a stake in the arse". After Sarajevo, Matija went to Istanbul (though the exact dates cannot be ascertained), and according to some legends even further, to Suez and the Egypt. In 1852 Matija was back to Novi, where he settled until growing ill in 1879. He lived a secluded life until the symptoms of mind degeneration have started to show, finally dying in the sanatorium of a well-known psychiatrist Richard von Krafft-Ebing, near Graz, on April 17, 1881.
