Learning from BABE vs SABER and from our past MTDGI we will have to make a different aproach in how to invade FREE, a more ruthless and annoying one:
1st - We should get Magnetism just in time for the fleet of 10-15 galleys to be upgraded to galleons and take 2x times more troops and in a sea not explored/watched by the enemie kinda like the japs did in pearl harbor.
2nd - We need some sort of bate manouver, some galleys stacked (3 should do it) going the direct path through coastal highway in order for them to believe we dont have magnetism yet, and we must make sure they see this galleys coming, and hopefully they will send units to cover the coast on that side leaving the north for us to kill and plunder.
3rd - Our target should be the north shore, as far from the core as possible, were we can do more damage and rape as we feel like it with greater change for establishing a beach head.
4th- Take a settler to build a city so that units wont lose turns if we need to reinforce for future conquests, we can rush a walls there and dug in.
5th- As for fleet composion, im thinking pikes, muskes (these would be excellent if BABE can get it for us), trebuchets(upgrade to cannons later) and some mdis to kill their cav units and so on. Im thinking 10/15 galleons carrying 40-60 units and 3 galleys carrying 6 pikes.
40 units:
1 Settler
1 Worker - joins and rushes walls on 2nd turn
3 Longbowmens
5 Trebuchets
10 MDI´s
15 Pikes
5 Muskes
As for battleplan:
Route 1 - 3 Galleys with 4 pikes to decoy and cut reinforcement path to our real landing zone
Route 2 - Landing "Hot" Zone, the only place i can see we can make city and still cut their continent in half while providing a lot of destruction to coastal notrhern cities.
Route 3 - Send a galleon with 3 Mdi´s and 1 Pike through this path behind enemy lines, as in bellow picture:
So:
- disconnect iron and pump warriors and spears
- how do we build 15/20 galleys?
- we need to get more map information! i hate all these black screen stuff and BABE could help us here;
- we need to find out if Council already as gunpowder/astro....they could trade it to free....
Can this be accomplished without FREE/COUNCIL having Mil Trad? i dont think so...so they will be able to through at us Horsemans, MDI´s, their cities will have enkidus by the hundreds and lots of artillerir units, so for this plan to sucede there must be absolute surprise and this is a gamble since the military advisor will betray us in no time...i hate that guy

When Cavalry joins in it will be the end for our troops, so we need more intelligence where their strategic resources are located... BABE can helps us here again.
