The edition examines the manuscripts, history and significant variants of Le Crève-Coeur and of 'La Rime en 1940'. Aragon's claim that the collection has its origins in World War 1 is considered, but little evidence for this is found. A more likely catalyst is the colonial war in Morocco of 1925-26 that led to Aragon's conversion to Communism. It is in the 1930s that the poet develops his strategy of poetry as a 'contrebande' against war. The principal influences on Aragon in this undertaking are evoked. A survey is given of the political and historical circumstances of Le Crève-Coeur, and they are shown to be indivisible from the poetry. The main themes of the collection are considered and the degree to which the 'contrebande' technique affects their accessibility. A detailed discussion of 'La Rime en 1940' and of each poem, stanza by stanza, follows.
