Read the excerpt from act 5, scene 8 of The Tragedy of Macbeth . Macbeth and Macduff are fighting each other. At another location, the leaders of the rebel army are evaluating the progress of the battling forces at the castle. A stage direction has been added in the middle of the excerpt. Retreat. Flourish. Enter, with drum and colours, MALCOLM , SIWARD , ROSS , the other Thanes , and Soldiers . Malcolm: I would the friends we miss were safe arrived. Siward: Some must go off: and yet, by these I see, So great a day as this is cheaply bought. Malcolm: Macduff is missing, and your noble son. [ ROSS approaches SIWARD with head slightly bowed and a somber expression . ] Ross: [ To SIWARD.] Your son, my lord, has paid a soldier’s debt: He only lived but till he was a man; The which no sooner had his prowess confirm’d In the unshrinking station where he fought, But like a man he died. Siward: Then he is dead? Ross: Ay, and brought off the field: your cause of sorrow Must not be measured by his worth, for then It hath no end. What does Ross’s added stage direction most contribute to the scene?
