Act V. Buckingham is taken and put to death; but Richmond's forces gather head. Richard leads his army to oppose them. The armies front each other at Bosworth Field near Leicester. The night before the battle the ghosts of the many slain during the progress of the Wars of the Roses menace Richard and promise victory to Richmond. In the battle that follows Richard is slain. Richmond takes oath to end the Wars of the Roses by marrying Edward's daughter, so that the two royal houses may at last be joined. _Richard III_ is the last of the great historical plays about the Wars of the Roses. The subject of the wars had occupied Shakespeare's mind for many months. He had traced them from their beginning in the long ago to their end among the dead at Bosworth. All that bloodiness of misery was due to a forgotten marriage and the chance that Edward III had seven sons, the eldest of whom died before his father. In this great tragic vision Shakespeare saw the wheel come full circle, with that giving of justice which life renders at last, though it may be to the dead, or the mad, or the broken. Largely, this play deals with the coming of that justice. Much that is most wonderful in the play comes from the faith that blood cruelly or unjustly spilt cries from the ground, and that the human soul, wrought to an ecstasy, has power, as the blood has power, to draw God's hand upon the guilty. But Shakespeare's mind was also occupied with the knowledge that self-confident intellect is terrible and tragical. One of the truths of the play is the very sad one that being certain is in itself a kind of sin, sure to be avenged by life. The obsession of self-confidence betrays person after person, to misery or death. All the heads that lift themselves proudly go bloody to the dust or bow in anguish. Only one man moves by other light than his own. He is the only one who achieves quiet triumph. Nothing in the play is more impressive than the speech in which the intellect that has ended the bloodshed prays humbly that God may bless and help England with peace.
