Glozelle

Glozelle was a Telmarine lord in the service of King Miraz, he was also the general of the Telmarine army. During the Narnian Revolution Glozelle and fellow lord Sopespian plotted the death of their king. They planned to overthrow king Miraz and take over the kingdom themselves. After talking King Miraz into accepting the challenge to a duel with Peter Pevensie, Glozelle served as a Marshal of the Lists along with Sopespian for their king. During the Duel of Aslan's How, Sopespian betrayed and killed Miraz, blaming it on Peter Pevensie. Glozelle and Sopespian then attacked Peter Pevensie, but Peter killed Glozelle. However in the movie Prince Caspian, Glozelle has a chance to kill Caspian, but lowers his weapon only to be attacked by a tree.

After Miraz
Glozelle was the first who voted to except Aslan's offer of a new home and go through the door that Aslan made into our world, where he presumably lived the rest of his life.

In the book
In the book, as well as the BBC film, Glozelle does not appear until near the end, in which he and Sopespian conspire against Miraz and talk him into accepting Peter's challenge. When Miraz falls (in the BBC he is wounded by Peter) Glozelle stabs him dead as revenge for an insult he gave him. In the book his fate is unknown, but in the BBC film, Peter immediately fights him and kills him by stabbing him.
