|| Movie-based Information|
The following information originates from the Chronicles of Narnia movies, as opposed to C. S. Lewis' chronicles.
Lord Donnon was a Telmarine lord who served on the Telmarine council during the reign of the usurper Miraz.
During the Second Battle of Beruna, Lord Donnon and several other Telmarine lords led regiments of Telmarine infantry, to attack the army of Old Narnians at Aslan's How.
After the awakened trees arrived, forcing the Telmarines to surrender, nothing was mentioned regarding the Lord. It is most likely that he died in the battle.
