What is the author's style in Lieutenant Hornblower by C. S. Forester?

The novel is told from the third-person, limited, point of view. The narrator is reliable, entirely effaced, and unnamed. Bush, the main character, is one of two central protagonists and a central figure in all of the scenes in the novel. The narrator divulges frequent internal thoughts of the protagonist, but not of other characters. The majority of the story is told through action and dialogue; revealed thoughts are frequent but generally are used for characterization rather than plot development.
