The Ballad of the White Horse is a poem by G. K. Chesterton about the idealised exploits of the Saxon King Alfred the Great, published in 1911. Written in ballad form, the work has been described as one of the last great traditional epic poems ever written in the English language. The poem narrates how Alfred was able to defeat the invading Danes at the Battle of Ethandun with the aid of the Virgin Mary.
The poem consists of 2,684 lines of English verse. They are divided into stanzas, typically consisting of 4 to 6 lines each. The poem is based on the ballad stanza form, although the poem often departs significantly from it. Types of metrical feet are used more or less freely, although there is often basic repetition in a line.
