Last Dying Breath is the song of Swedish band Sabaton, dedicated to the defense of Belgrade on Octrober 1915. and the following famous speech of major Gavrilovich:
"Soldiers, exactly at three o'clock, the enemy is to be crushed by your fierce charge, destroyed by your grenades and bayonets. The honor of Belgrade, our capital, must not be stained. Soldiers! Heroes! The supreme command has erased our regiment from its records. Our regiment has been sacrificed for the honor of Belgrade and the Fatherland. Therefore, you no longer need to worry about your lives: they no longer exist. So, forward to glory! For the King and the Fatherland! Long live the King, Long live Belgrade!"
