The Opel Blitz (Lightning of course) was introduced in 1932 and so named because it had a German-made version of the Buick-based Marquette 6-cylinder engine suposedly affording speed. The name was of course used throughout the war on Opel military trucks, and I have a photo of a 'Bedford Blitz', i.e. Bedford TM tractor unit showing that the name lived on into the Seventies.
However round here the 'Blitz' is always remembered as something else entirely. Southampton was bombed very badly and an old ruined church inthe city centre remains as a memorial.
