Macbeth Act V, Scene iv Summary

Malcolm, Siward, and Macduff meet with Menteth, Cathness and Angus, Lennox, and Ross at Birnam Wood. A plan is hatched to have soldiers cut down some branches to hide themselves under during the march to Dunsinane.
Many of Macbeth's men have deserted him, and it's clear that those still siding with Macbeth don't believe in the cause. Still, Macbeth is so set in his certainty of victory that he is willing to let them march right up to Dunsinane, thinking the castle (and he) is protected from harm by the witches' prophecy. At this point, it might be wise to review that prophecy.
