The war poet came into currency during the First World War, but has diminished since the Vietnam war. Most such poets were soldiers. These are among the best known:
Rupert Brooke After this first shocking experience of war, the young British poet wrote five sonnets, the best known of which is The Soldier. He died in 1915 of blood poisoning at age 27 after a mosquito bite on his lip became infected.
John McCrae The Canadian-born Mr. McCrae, an army surgeon in the First World War, is most famous for penning In Flanders Fields. He died of pneumonia in 1918 in Boulogne, France, aged 45.
Siegfried Sassoon The decorated British First World War soldier didn't spare the truths of the trenches from his poems, including details such as rotting corpses, mangled limbs, filth, cowardice and suicide. He later turned against the war, and is best remembered as a writer of satirical anti-war verse. He died of cancer in 1967 as age 80.
