S 
Sassoon, Siegfried (8 September 1886 – 1 September 1967), was one of the first patriotic volunteers for the British army. He was exceptionally brave, but some of his comrades called him "Mad Jack", because he took far too many risks. When Sassoon became horrified by the realities of WWI, he started to write very critical poems. His letter Finished with the War: A Soldier’s Declaration. (July 1917) caused a political outrage. Sassoon's friends were afraid he might be court-martialled, since he refused to return to his regiment, and arranged for him to be sent to hospital, where he was treated for "shell shock". At hospital he met Wilfred Owen and both became close friends. After Sassoon had finally decided to return to the front, he was wounded again, but survived. He is remembered today as one of the leading British war poets.
