Your 196.¹ British Ambassador at Washington told me all traffic was diverted to Northern route because they do not have Cobh and Berehaven. This makes convoy easier target because one line is more vulnerable than two. Is it not the case that time would be required to fit these places for destroyers, protective guns, etc., that Germans could break up such preparations, and that supplies would have to be brought in through supply lines easy to attack? Any argument on these lines extremely useful.
