Shortly after Disney released Dumbo in October 1941, the US entered World War II. The US Army and Navy Bureau of Aeronautics contracted most of the Disney studio's facilities where the staff created training and instruction films for the military like Aircraft Carrier Landing Signals, home-front morale-boosting shorts such as Der Fuehrer's Face,[100] which won an Academy Award,[101] and the 1943 feature film Victory Through Air Power.[102] Military films did not generate income, and the feature film Bambi underperformed on its release in April 1942.[103] Disney successfully re-issued Snow White in 1944, establishing a seven-year re-release tradition for his features.[103] In 1945, The Three Caballeros was the last animated feature released by the studio during the war.[104]
