Now when you have a battle, what about the terrain? You do have an idea from the map, hexagons of 3.2km. Then one can use another of Zucker game the 3days of 1809 concentrated on the Abensberg-Eckmühl part with more details, then his battle games. The thing is, there is a high possibility that battles won't happen where they did. So I searched and found a way. Three sites do the job. One is the world in a very clever interactive topographic map that gives you heights in a vivid way. Mostly these would not have changed much in the countryside, whatever was constructed on top. Then another gives Maps of Germany around 1848. So take away the first trains, shrink a bit cities in case of need, and off you go. Detailed maps, that can be crossed with the preceding ones. Once one gets in the depth of Austria towards Vienna, unless Charles performed miracles, the third site gives you a stunning view of the place in absolute details at about the right time. Another one can be useful too. relatively accurate terrain can now be done for each engagement. Do think deeply about use of terrain by both sides and what can likely happen. Nothing different from usual scenarios though, not to spoil the game by having for example most defensive positions too close to the end of the world, wasting table space and generally making the game silly. (that absurd secure flank?).

Then don't be carried away with thinking that what you see on the strategic map is so close to reality! In the first trials, I optimistically thought my Bavarians would do a delaying action around this Landau an der Isar. Looked possible. then I looked for the real terrain. Well it would work nicely if... the sides were reversed. Heights and obstacles are all on the south bank of the river, on the Austrian side! and the town itself was not much to defend. A bit of work but worth it..
