good. For the first time, a substantial number of important British poets were soldiers, writing about their experiences of war. A number of them died on the battlefield, most famously Edward Thomas, Isaac Rosenberg, Wilfred Owen, and Charles Sorley. Others including Robert Graves, Ivor Gurney and Siegfried Sassoon survived but were scarred by their experiences, and this was reflected in their poetry. Robert H. Ross describes the British "war poets" as Georgian poets. Many poems by British war poets were published in newspapers and then collected in anthologies. Several of these early anthologies were published during the war and were very popular, though the tone of the poetry changed as the war progressed. One of the wartime anthologies, The Muse in Arms, was published in 1917, and several were published in the years following the war. David Jones' epic poem of World War I In Parenthesis was first published in England in 1937, and is based on Jones's own experience as an infantryman in the War. In Parenthesis narrates the experiences of English Private John Ball in a mixed English-Welsh regiment starting with their leaving England and ending seven months later with the assault on Mametz Wood during the Battle of the Somme. The work employs a mixture of lyrical verse and prose, is highly allusive, and ranges in tone from formal to Cockney colloquial and military slang. The poem won the Hawthornden Prize and the admiration of writers such as W. B. Yeats and T. S. Eliot. In November 1985, a slate memorial was unveiled in Poet's Corner commemorating 16 poets of the Great War: Richard Aldington, Laurence Binyon, Edmund Blunden, Rupert Brooke, Wilfrid Gibson, Robert Graves, Julian Grenfell, Ivor Gurney, David Jones, Robert Nichols, Wilfred Owen, Herbert Read, Isaac Rosenberg, Siegfried Sassoon, Charles Sorley and Edward Thomas. For much of the Great War, G.K. Chesterton supported the British Empire's war effort against Imperial Germany. By the end of the war, however, Chesterton was singing the same tune as anti-war poets Siegfried Sassoon and Wilfred Owen. In his 1922 poem Elegy in a Country Courtyard, Chesterton wrote: The men that worked for England They have their graves at home: And birds and bees of England About the cross can roam. But they that fought for England, Following a falling star, Alas, alas for England They have their graves afar. And they that rule in England, In stately conclave met,
