Caithness, a Scottish nobleman

[This is an annotated list of all appearances and all mentions of the three Witches.]

Caithness is one of the leaders the Scottish forces that are marching to join Malcolm and the English army in Birnam wood in preparation for an assault on Macbeth's castle. When someone asks about Macbeth, Caithness says "Great Dunsinane he strongly fortifies: / Some say he's mad; others that lesser hate him / Do call it valiant fury" (5.2.12-14). Caithness goes on to speak of how Macbeth is out of control. At the end of the scene he pledges their blood to cure Scotland of the sickness that is Macbeth. [Scene Summary]

Drum and colours. Enter MALCOLM, SIWARD and YOUNG SIWARD, MACDUFF, MENTEITH, CAITHNESS, ANGUS, LENNOX, ROSS, and Soldiers, marching(5.4.1, s.d.). He says nothing, but Caithness is with the joint Scottish and English forces that enter Birnam wood before Macbeth's castle. [Scene Summary]

Although he is not named in the stage directions, Caithness is probably among the thanes who are present at the end of the play, and who honor the victorious Malcolm by shouting "Hail, King of Scotland!" (5.8.60). [Scene Summary]
