You are right, I didn't notice that, but the artillery shown in the 3 units list is still the one on the mountain west of it. And on the tile southwest of the damaged Dutch infantry, there is no artillery (mountain, no road).
This question is actually both hard and very easy to answer. An easy answer would be "from nowhere." A harder answer would be "from me in the first place." Scroll up one post and click on the link that reads "Food for thought" in the Bartleby quote from the Money maker thread to get a basic outline of how this works.

Ever seen an AI in Feudalism?
I think if you go over there and refresh your map of the area, you will find that it is connected (colonies get a free road remember). It would look similar if they built a town in the same place; your fogged map would not show the connection of the road that you already saw to the new town, even though of course such a connection exists.
Edit: oops, this was an inglorious use of my 1000th post. I was saving it for some earthshattering revelation about Civ3 strategy that would overturn the whole way we think about the game!
