13 September – On this day

The British bring heavy units of the Royal Navy nearer to the likely invasion area.

The battleships Nelson and Rodney (sister-ships) join the Hood at Rosyth (Scotland) and the Revenge is at Plymouth. There are, of course, strong cruiser and destroyer forces in relevant positions.
