And Adriano, thanks for your ongoing support and comments. The searchlights are often mentioned in the Steinbock documents, and were obviously visible on at least some operations. But I'm sure you're right that in the depths of winter, they were not always easy to detect! The same is true for the Lux buoys sometimes used to mark turning points in the North Sea. Another navigational aid - which I'll mention in the text box accompanying the map - were star shells fired in various patterns by flak guns along the coastline. These were indicated on the ADI(K) 91 map, although at the time the map was captured, the meaning of the symbols was unclear to British air intelligence. It was explained soon afterwards, however, in ADI(K) 118. The map will become too 'busy' if I try to include the symbols, but as I say, I will refer to this in the text.
