This was the period when the RAF were bombing the potential
invasion ports in France and Belgium. On the date in question
Blenheims of 101 Squadrom bombed Boulogne Harbour
and shipping in the harbour, 2 aircraft were lost.

Thanks, K. The facility is shrouded in darkness and only a few large dockside
cranes are visible against the massive explosion, so its probably not possible
to determine at this point which port was struck in the photo.
