The IWM holds the newsreels. No sound, but in a way that’s not so unfortunate if you know what you’re looking at, because it takes away the pathos and the received pronounciation.
This one shows quite a few interesting things. ‘Bush’ artillery (captured Italian guns) being fired; a quite comprehensively destroyed Panzer IV; the bombed out wreck of the Italian navy’s obsolete armoured cruiser San Giorgio, amongst others.
Well worth your time!
