As WWII wound down, the good people at the British Ministry of Information cobbled together this feature (as well as two others in the series, reviewed separately) from various newsreel footage, then sent them out, as they proudly announce in an interstitial prelude, to (vanquished) people speaking 16 different languages. This generous public service had the not so subtle subtext of "Guess what? You lost--big time. And here's film to prove it."
These mini-documentaries no doubt played better in Allied theaters, where the sometimes brutal footage at least let the victors know their sacrifices were not in vain. This was, after all, the last "good war."
This particular part of the trilogy starts with the Normandy invasion and follows the fighting through the liberation of Paris. It's generally well-done, with that understated British flair, with good coverage of Bradley's work to free Cherbourg and De Gaulle's triumphant entry into Paris, where he was quickly shot at by secreted German snipers.
The film is probably best seen as the historical relic it is--don't expect any in-depth analysis or even basic sympathy for the Germans. In 1945-46, political correctness was a thing unheard of, and calling a bad guy a bad guy was de rigeur. That said, there's a bit of unintended irony when the music editor chooses Beethoven as triumphal underscore music for the liberated French.
