Actually, we have a very good chance of taking that city. There is only one pikeman on that tile, every other unit is a gallic swordsmen. If they settle the city on the hill, and fortify all of those units.. that will give all of their units a bonus of +125%. I'm not 100% sure how those defense bonus's actually add up. If they are bulked together into one bonus and then applied, that will give the Pikeman a defense of only 3.75. However, I believe that each bonus is applied seperately.. so doing the math:
Pikeman:
50% * 3 = 1.5 (50% for hill defense bonus)
25% * 3 = .75 (25% for fortifiction bonus)
3 + 1.5 + .75 = 5.25 defense bonus
Gallic Swordsman:
50% * 2 = 1 (hill defense)
25% * 2 = .5 (fortify bonus)
2 + 1 + .5 = 3.5 defense bonus
There is 1 pikeman and 7 gallic swordsman (counting the two that are NOT on the hill). So doing some more calculations
6.75 * 1 = 5.25
3.5 * 7 = 24.5
5.25 + 24.5 = 29.75
29.75/4 = 7.43 (rounding to 7 for simplicity).
So, a good estimation for taking the city is around 7 immortals. Of course, this assumes that all units are on an equal footing hit point wise. The galls do not have a single regular unit in their entire army. Three of the gallic swordsmen are elites. We have 6 immortals in our current army, 2 of which are veterns and one is elite.
Our immortals (against the pikeman) are always at a negative, thus if we use one of the regular immortals on a "suicide run" to just knock the Pikemans hp down some, we can focus on hitting some of the gallic swordsman. Our vet immortals have a 57% chance of killing a vetern gallic swordsman and a 44% chance of killing an elite gallic swordsman. Our elite immortal has a 71% chance of killing a vet gallic swordsman and a 58% chance of killing an elite gallic swordsman. Our regulars have a 41% chance of killing an vetern gallic swordsman and a 29% chance of killing a elite swordsman.
I propose we throw a suicider at the pikeman, just to knock his hp down and make the gallic swordsman defend. We try to save our elite immortal for as long as possible though, because even if we manage to knock the pikeman down one hp.. our elite immortal then has a 65% chance of defeating him. We then throw our remaining regular immortals against the elite swordsman. Not in any chance of winning, but just to get them out of the way. Once possible, we try to hit the vetern swordsmen with our vetern immortals. Hopefully one or two of our immortals will be promoted to elite.
If we switch to immortals in Dancing Banana, Semtax, Grenadeoplis, and Dynopolis and rush the two in Grenadeopolis and Dancing banana (for 108 gold) we can get two more veterns and two more regular immortals on the way. Bringing our total troop number to 10 immortals, 1 elite, 4 vet, and 5 regular. If we use the regular immortals as suicides just to knock down the elite gallic swordsman and pikeman hp.. our vetern and elite immortals can pick them off pretty easily.
Another idea (that I'm kind of leaning to), is building 4 trebuchet instead of four immortals in the city above. We have 5 pikeman in that stack, there is no possible way they can hope to even strike at our immortals, much less the trebuchet. There is no need to rush to the city and attack immediantly. We can rush four trebuchet and use them to bombard the city, picking off units when possible. Meanwhile, we rush 4-5 additional immortals to use as a strike force. We could also try to knock the pikeman out using a the trebuchet, then use our elite immortal to attack an elite gallic swordsman (58% chance in our favor). Hopefully picking off one elite gallic swordsman before the main battle even starts.
We can even keep that up for several turns (or untill our elite immortal dies). Attack an elite with our elite, move back and heal him up... and repeat. The only problem with taking our time, is that they might rush walls in the city. Which, in all honesty, isn't much of a threat. We can just build more trebuchet and weaken the units even more before we strike. What the threat of walls is that it means that we will have to take longer to capture the city, allowing the galls the possibility of sending in reinforcements.
--------------------
This will be the perfect oppertunity to force K.I.S.S. off of our continenet.. and to strike a devasting blow to their army. We destroy 7 gallic swordsmen, 1 pikeman, and we capture a trebuchet. We also destroy a settler (or maybe capture a city). I prefer using the trebuchet method of attacking the city, take our time and try to minimize our casualities, while we maximize theirs. Maybe even get the city up to size 2 and capture it.
In the end, we have to destroy/capture this city. We will not beable to flip it, as we have no culture in that area and I'm almsot certain that their just going to rush a library. We would need culture on a level only Dancing Banana and Semtax is capable of. Flipping the city is not an option.
