Wilfred Owen was an English poet who is widely regarded as one of the greatest war poets of all time. He wrote extensively about his experiences in World War I and his works are known for their powerful imagery and condemnation of war. Owen was killed in action in 1918, just one week before the end of the war. His most famous poem, 'Dulce et Decorum Est, ' is a searing indictment of the horrors of war.
