Errores

The section of the film detailing Germany's prewar conquests contains several errors. The narrator states that Germany occupied the Rhineland in March, 1934. In fact, it was in 1936. Immediately after, a map inaccurately depicts the dismembering of Czechoslovakia in October 1938 and March 1939. The 1938 map depicts Germany annexing the Sudetenland, which is somewhat incorrectly drawn upon the map, but neither it nor the narration shows Hungary annexing the southern portion of Czechoslovakia, nor Poland taking the Teschen district in the center north of the country, both of which occurred simultaneously with Germany's occupation of the Sudetenland (The narrator also speaks of the Sudetenland going "back" to Germany, though, in fact, it had never been part of Germany). When the final dismemberment of Czechoslovakia in March 1939 is depicted, Germany is shown annexing outright, not only the western Czech lands of Bohemia and Moravia (which it did annex), but the center of the country as well; meanwhile, the extreme eastern end of the country is labeled "Slovakia," the nominally independent satellite state recognized by Germany. In fact, Slovakia was located in the center of the country, in areas inaccurately depicted as annexed to Germany; the eastern portion labeled "Slovakia" in the film is, in fact, an area then known as the Carpatho-Ukraine, which was annexed by Hungary the day after Germany occupied the Czech lands in the west (and is today part of Ukraine). Poland also received more Czech territory in March 1939.

The close up shot of the Spitfire firing its guns shows the undercarriage is in the lowered position, proving the footage is actually from a ground firing test.

As a result of reverse printing, the swastikas on the tails of the attacking Dorniers are shown backwards, although the ones on the body of the attacking bombers are shown correctly.

The fighters attacking the Wellington bombers are actually RAF Spitfires - the distinctive asymetric radiator can clearly be seen on one example as it turns away.
