Robert Jordan is an American who lived in prewar Spain and fights as an irregular soldier for the Republic against Francisco Franco's fascist forces. An experienced dynamiter, he is ordered by a Soviet general to travel behind enemy lines and destroy a bridge with the aid of a band of local anti-fascist guerrillas to prevent enemy troops from responding to an upcoming offensive. On his mission, Jordan meets María, a young Spanish woman whose life has been shattered by her parents' execution and her rape at the hands of the Falangists (part of the fascist coalition) at the outbreak of the war. His strong sense of duty clashes with both the unwillingness of the guerrilla leader Pablo to commit to an operation that would endanger himself and his band and Jordan's own new-found lust for life, which arises from his love for María. But times are such that love cannot survive and blossom in the midst of intrigue, betrayal, cruelty and death. The novel is based on Hemingway's own experiences during the Spanish Civil War.
