Which Narnia novel won the 1956 Carnegie Medal?

The Narnia novel that won the 1956 Carnegie Medal was The Last Battle. C. S. Lewis received the annual award for the final book in The Chronicles of Narnia.

The Last Battle was published in 1956 as the seventh and concluding Narnia novel. The Carnegie Medal, administered by the Library Association, honoured the year's best children's book by a British subject, making the award a significant recognition of Lewis's work in British children's literature.

The novel takes place roughly 200 Narnian years after The Silver Chair and brings the world's story to its dramatic end. Its plot involves a false Aslan, the ape Shift, the donkey Puzzle, and a final conflict between Narnia and Calormen. The series concludes when Aslan ends the old Narnian world and welcomes its faithful inhabitants into his own country.

A common mix-up is choosing another Narnia title because the books are often discussed as a single series. The Last Battle is the only Narnia novel to win the Carnegie Medal, and its award came in the same year as its publication.
