The 60-minute documentary was the fifth of the Army Special Service's "Why We Fight" series. Assembled under the supervision of Lt. Colonel Frank Capra, the film is a sublimely assembled collection of authentic newsreel footage from both the U.S. Signal Corps and various Soviet sources. Narrated by Anthony Veiller, Battle for Russia is designed to clarify the history of America's Russian allies to military and civilian audiences alike, and to emphasize the importance of Russo-American cooperation in defeating the Nazi juggernaut. The film's highlight is the siege of Stalingrad, alternately terrifying and awe-inspiring. The musical score was by Russian expatriate Dmitri Tiomkin, who'd previously collaborated with Capra on Mr. Smith Goes to Washington.
