Tank Battle: Royal Armoured Corps Film.

[Sheldrake]

I bought a DVD a few years ago called "British Tanks at War: Five wartime films" D22844 copyright IWM 2006

The first of these was called "Tank Battle" and lasted around 30 minutes and had a U certificate for general release. I think it is mentioned somewhere in Brooke's diary. The film is evidence of the lack of all arms co-operation perceived by the RAC. The film shows the defeat of a German armoured column by tanks in Sussex. An air force Lysander provides the information and an armoured column intercepts the invaders. No other arm of service is either mentioned or shown.

Searching the IWM does not bring up details of the film, but the rushes are here. https://film.iwmcollections.org.uk/record/1701
They were flimed in mid 1941 which probably gives a release date of early 1942.
