Testing with 10 Scouts indicates the Scout just stays in place getting hammered by the Catapult over and over each turn. Catapult gets 1xp each time and 2 great general points ya. I'm starting to like the idea of farming great general and regular xp off that scout. Here is a good view of Sitting Bull. Spoiler : I'm now thinking of attacking Mound City T151 with 2 Muskets and 2 Muskets from a galley (the injured 7.9/9hp musket). Our Catapult is too slow and won't be able to bombard Mound City until T153. The good news is that testing indicates that our land muskets get 72% odds with 20% city defenses if it is just Archers. If our Trireme sees a Longbow or Catapult in Mound City on T150, we can change plans easily. Caravel can grab spy this turn and sail to 2N2E of Choco Canyon T150 while getting a good look at Choco. Our trireme can sail 1S this turn and blockade, then 1S again on T150 and blockade. From this spot trireme can protect our galleys and blockade 2 cities at once. The Caravel and Trireme will be needed to push to Choco I feel since Sitting Bull has 2 Galleys down there somewhere. I'm pretty sure I can waste Sitting Bull's capital with just the blockade and 2 units. 1 Chariot (no xp) can stand on the rice tile as long as the surrounding roads are pillaged The more southern rice can be stood upon by 1 musket (no xp). Cahokia will naturally starve down to 2 population and be useless in the future.
