He was a talented and popular poet who contributed to 'The Yellow Book' a publication featuring poetry, art and prose during the late 1800s. However, possibly because of his criticism of the Boer Wars, Watson was not chosen as Poet Laureate. He was married to Adeline Maureen nee Pring and the couple had two daughters.During the First World War Watson's very patriotic poems earned him a knighthood in 1917. Largely forgotten after the War, Watson died on 13th August 1935.
Watson’s collections of WW1 poetry were:'A Hundred Poems' (Hodder and Stoughton, London, 1921)
'The man who saw and other poems arising out of the war' (Murray, London, 1917) – available as a free download on Archive'The superhuman antagonists, and other poems' (Hodder and Stoughton, London, 1919)
William Watson's poems also appeared in 23 anthologies of First World War Poetry.Source: Wikipedia and Catherine Reilly’s ‘English Poetry of the First World War: A Bibliography (St. Martin’s Press, New York, 1978) – p.330
