Try this one on for size. I,ve been reading a book on the breakout and pursuit from Normandy after the D-day landings,it has lots of maps detailing the movements of Allied and German forces.I love detailed maps.I,ve also been following the Ukraine movements on maps,along with the breakout and retreat from Chosin Reservoir in Korea. I have found myself at night,with my mind applying the movements to maps of Tolkien,s War of the Rings,in my head,at 3:00 AM. Encirclement and destruction of Sauron,s forces at the battle of the Pellenor! With weapons and troops available at the time!
