The Battle of Miraz's Castle, or the Telmarine Castle Night Raid, was a surprise attack of the Old Narnians on the Telmarine-Narnian royal castle, during the Narnian Revolution. Because the main Telmarine army was preparing for war on Aslan's How, and not guarding their castle, High King Peter decided to attack it. Although Caspian X was against it at first, claiming that no one had ever taken the castle before, he was eventually pressured into agreeing.
