Forester lived in the United States during World War II and wrote propaganda aimed at getting America to enter the war. By then, he had at least 27 novels to his credit. Winston Churchill was an admirer as was Ernest Hemingway.
There were a dozen novels in the Horatio Hornblower series. The first was The Happy Return (1937), in which Hornblower is a junior Royal Navy captain on secret mission to Central America. Hornblower appears in short stories, and several of the novels have been published together in omnibus editions.
Both the Hornblower series and The African Queen have been adapted for films.
