Glozelle

Glozelle was a Telmarine lord in the service of King Miraz, and he was also the general of the Telmarine army. During the Narnian Revolution, Lord Glozelle and fellow Lord Sopespian plotted the death of their king just as their king had plotted the death of his brother, to become king in the first place. They planned to overthrow king Miraz and take over the kingdom themselves by talking King Miraz into accepting the challenge to a duel with Peter Pevensie. When they did so (by cleverly using Miraz's own arrogance to encourage the idea) Glozelle served as a Marshal of the Lists along with Sopespian for their king. Glozelle was especially turned against Miraz by an insult Miraz made at him that morning, though Glozelle continued to pretend to be loyal until the opportunity would arise to betray the arrogant king.

During the duel at Aslan's How, King Miraz fell when trying to stab Peter and in return Peter stabbed him in the chink of his armor. Caspian X refused to kill him, though. Sopespian feigned trying helping Miraz up, but discreetly stabbed him with Susan's arrow. Glozelle and Sopespian blamed Miraz's fall on a false move by the Old Narnians, therefore justifying that their army spontaneously charge at the Old Narnian Army, beginning the Second Battle of Beruna. Glozelle charged back to the Telmarine Army and ordered for his calvary to charge. In the end of the battle, Glozelle prepared to stab Caspian X with a spear but hesitated and placed the spear down (showing honor). He the was knocked out by the revived trees. He later became one of the three Telmarines that were the first to leave Narnia and go back to Earth: the ones blessed by Aslan.

Trivia

 * Glozelle's name can be traced to the old English verb gloze, meaning 'flattery or deceit'
 * In the BBC film as well as in the book version of Prince Caspian, Glozelle does not appear until near the end (before the battle), in which he and Sopespian conspire against Miraz and talk him into accepting Peter's challenge. In the BBC version, however, when Miraz falls he is wounded by Peter and Glozelle stabs him dead as revenge for an earlier insult he gave him. He then attacks Peter, only to be killed by him.
 * Glozelle is in the Disney film version, where he is portrayed by Italian actor Pierfrancesco Favino. This Glozelle is Miraz's general whom he orders to assasinate Prince Caspian. He stands by as Sopespian murders the Usuper King, and survives the Battle of Beruna. He is the first to agree to return to the South Sea, from which all Telmarines originate, and Aslan promises him a good future. Despite serving Miraz, he is also portrayed as an honourable soldier (along the lines of a chivalrous knight or a Bushido following Samurai) as he is shown to take responsibility for his mistakes instead of blaming them on his subordinates.
 * In the book, he and Sopespian are depicted as tall men with capes and pointed caps.
