Make sure that General Catroux has a talk with the Joint Planners or Joint Intelligence Committee about the terrain and defences of the Mareth, on the southern frontiers of Tunisia. The General knows all about this line, having commanded there, and very expert information should be forthcoming from him. The largest scale maps should be available, and a report should be made which I can forward to Generals Alexander and Montgomery.
