How are Cordelia and Lear reunited?

Hearing of her father's fall from grace from Kent, Cordelia persuades her husband to let her return to Britain with a royal army and win back her father's kingdom for him. Lear is found by Cordelia's army, wandering near Dover. He is totally mad, singing to himself with a crown of straw, nettles and weeds on his head. The physicians advise Cordelia not to see her father until he is restored to health. When Lear is brought to his senses, a tender reunion takes place between the king and his daughter.
