For those who like to get a feel for what the desert looked like, and the period propaganda, the AP archive has a lot of Movietone reels online:
E.g. Rommel at Bay (with a nice view of the shortened Beaufighter wing referenced in this older post), of 18 December.
Or Rommel on the Run, of 15 January.
I used ‘Libya “World War 2″‘ as search terms.
Happy viewing.
