Eagles Over London (DVD)

Enzo G. Castellari directs this Italian war film. Using the chaos of the Dunkirk evacuation as a cover, a group of German agents take on the identities of English soldiers in order to gain access to England and take out radar installations along the coast. In order to infiltrate the British army, they kill a squad of English troops and take their ID tags. Army officer Captain Paul Stevens (Frederick Stafford) finds the dead men and realises that their IDs are missing. On his return to England he heads efforts to track down the saboteurs before they can inflict any further damage.
