The Battle of San Pietro is a 1945 documentary film directed by John Huston about the Battle of San Pietro Infine during World War II.
The film is unflinching in its realism and was held up from being shown to the public by the United States Army. Huston quickly became unpopular with the Army, not only for the film but also for his response to the accusation that the film was anti-war. Huston responded that if he ever made a pro-war film, he should be shot.
General George Marshall came to the film's defense, stating that because of the film's gritty realism, it would make a good training film; subsequently the film was used for that purpose. Huston was no longer considered a pariah; he was decorated and made an honorary major.
In 1991, The Battle of San Pietro was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant"
