Edward Thomas (1878-1917) was known chiefly as a prose writer and only wrote poetry during the last few years of his life, encouraged by his close friend, the American poet Robert Frost. Thomas is now widely regarded as one of the pre-eminent British poets of the twentieth century and poems such as ‘Adlestrop’ are among the best-loved in the language. His influence has been acknowledged by poets as diverse as W.H. Auden, Ted Hughes, Philip Larkin and Derek Walcott. He was killed at the Battle of Arras on Easter Day 1917.
