This collection documents the work of British Catholic poet Siegfried Sassoon through his letters and poems. His poem, "An Unwritten 'Essay on Satire'," is a three-page manuscript that he sent to Robert Graves. His printed poem "Rogation" was probably an enclosure in his correspondence with poet Katherine Kendall, which is included in this collection. The letters to Kendall discuss her work, as well as religious and modern poetry. Also included is Kendall's The Horizon and Other Poems (1963). Finally, there is one piece of correspondence from Sassoon to Addyes Scott in response to a fan letter.
