In the light of Graves' War Poetry (See previous blog post).
George Simmers, in his excellent Great War Fiction Blog, discusses Siegfried Sassoon's running commentary on Goodbye to All That which Sassoon had drawn pasted and written in his own copy. Sassoon, to use English Understatement, was not that particular book's biggest fan. The link below takes you to the blog. There is also a link in his post to the TLS article Simmers is discussing.
