Master maps rule. In 10 years of play I never opened the editor. Now I can't get away from it. Anyway, when I tried to model the Polish glider landings by the Johanna farm (3rd lift tue 19th) I noticed there was no rail road and embankment with culvert at the southern edge of the map, just the dirt road that was next to it. This matters because the Germans launched a large attack to overrun the landing zone as the polish gliders came in and retreating over the RR embankment and into Oosterbeek was the only way the para's could get out of the German attack. So, just put RR over the dirt road and elevate to about 44 and then a stone bridge with a dirt road under it to simulate the culvert used by the jeeps and you have a great LZ map with the Dreijenseweg, amsterdamnweg and Johannahoeve farm. This is a big senario but worth doing if you rig can handle 3-4 Battalions.
I would like to see a map to fill in the city area between Oosterbeek and the Arnham bridge if anyone can do that. There was much fighting as the para's tried to reach the bridge party.
