1239 AD (inherited turn): Micromanage cities to get Map Making down to 9 turns (-6 gpt, but that will go up as we lose troops in combat). Get rid of workers clearing forests (too productive in the Middle Ages) and send them to build mines.
The Anglo-Saxons invaded the Celtic Islands of Britain throughout the 5th and 6th centuries. The plan for the Celtic revenge on those Anglo-Saxons trespassers is shown below:
IBT: Byzantine Cataphract disembarks in Brittany from a Curragh (not a Dromon)! Remind me, when did we go to war with the mighty Theodora?
1242 AD: The German invasion force crosses the border.
IBT: There are at least 5 Byzantine curraghs off the coast of Brittany! Otto asks us to leave or declare war, we tell him to prepare for war.
Swordsmen from Bremen attack our advance scouts. Then,

21 German Swordsmen appear out of the fog and head our way. Not to mention the 7 or 8 that slay our initial Gaelic scouts. This is going to be WAY UGLY. Well keep our SOD up on the hills and hope for the best.
1245 AD: The Golden Age boost gets us down to 3 turns for Map Making. Attack and win in Germany with 3 elite swords, but no leader. Decide it is better to attack German swords in the woods (3:2.5) then have him attack us in the hills (3:3). So attack the biggest stack of 13 swords nearby with all our veterans. We wipe them out
I even had two spare swords.
IBT: Grim news. Germans promote an elite sword into a ML. Plus 10 more swords appear out of the fog, giving them 16 in northern Germany now. French are going to settle at Dorestad. Not a problem. We still want to get their help vs. Germany. Byzantine Curraghs circle but dont drop anyone off. Cataphract sprints east towards France???
1248 AD: Our units need healing. We make limited attacks trying to promote an elite, again no luck. Out catapults are helping immensely, but will the Germans ever stop coming??? Military advisor still calls us weak against them.
IBT: The news gets worse. 4 Byzantine Cataphracts unload next to Brittany. Doubtful it can hold. We lose about 10 units to German attacks; now knights are headed our way too. And we even see them move a king OUT of Bremen to safety in the south. Who are we playing against? Were now in danger of losing our army AND six catapults in Germany. Only 4 units remain in the stack guarding 4 of our catapults. But one silver lining
the German relic carrier has just appeared!
1251 AD: New strategy. Grab the relic and get the **** out of Dodge.
Elite sword attacks knight, falls but knight at 1 hp. 3/5 sword attacks spear and kills it. Guess who the next defender is??? 3/4 sword attacks, red-lines, promotes and kills the relic carrier. It is the Splinter! 3/4 sword attacks, kills knight, captures Splinter! But can we keep it???!! None of our units in that stack have more than 2 hp! I see if the Germans will make peace. Hah, no way! About the only thing I can think to do is threaten Bremen and see if that distracts the AI. That and feeding it some catapults. Shuttle some Spearmen over in a desperate attempt to save the catapults.
Byzantines are willing to make peace in exchange for Brittany. Ill lose it anyway, and it is hopelessly corrupt. I go ahead and make peace there. OK, crucial IBT segment here
IBT: The Germans play it smart and go after the relic first. It has no chance of holding. We do save 4 of the 6 catapults, but are going to have to evacuate Dunkirk-style.
The evacuation
1254 AD: Map Making comes in. We are in the final age. In our golden age here, we can also research Western Church in only 15 turns. Danes will now declare for Early Siegecraft and Map Making. We can do massive trade brokering now. Notice the Turks and Abbasids have Theology and Divine Right.
Trading goes like this:
Fatimid: we get WM+12g for WM+Early Siegecraft
Bulgar: we get WM for Code of Laws
Magyars: we get WM for Early Siegecraft
Poles: we get WM+16g for TM and Contact with Fatimids
Cordova: we get WM+1g for Early Siegecraft
Norway: we get WM+4g for Contact with Rus
Our world map now looks complete. Time to shop it around.
Danes: alliance versus Germany (just for the WM!)
Byzantines: we get 64g for WM
Abbasids: we get 27g for WM
Notice we have a tech lead on Poles and Magyars. We should be able to get them both to join alliances against Germany too. Well just have to make sure we are the ones to recapture the Splinter. Basically looks like I mistimed all this. If I had waited to attack them when we had all these allies, probably would have gone a lot better.
Poles: alliance versus Germany for Code of Laws
Magyars: alliance versus Germany for Map Making
Tough choice on what to research. Western Church will allow us to trade for and extort those techs. I saw Monasteries in the capitals of our Magyar and Pole allies. We cant build Knights though. Seamanship is the other tempting item. We need Harbors and Galleys badly coming from our island. We can also trade it to others (no one has it). I head for Seamanship. 18 turns in the GA.
Dunkirk is completed. Only 4 catapults, 2 Gaelics, and a Spear survived the invasion of Germany.
IBT: Abbasids demand 21g tribute. We refuse. They declare
we now have Casus Belli to take Jerusalem! A Danish longship sails past Germany. Otherwise quiet.
1257 AD: We see the Danish SOD being sent against Bremen.
The Danish Stack-of-Death
Once they take Bremen, we should negotiate ROP with the Danes and unload all our troops there before marching into Germany. Im going to get a Settler and defensive troops ready to get us a port when Bremens cultural bubble bursts.
Young William Wallace awakes with a start in the Celtic capital of Glascow, in the province of Dalraida. It is the same nightmarish dream again. Once again, he is running over the hills and forests of Germany. His now-dead father, slain in the first Celtic/Saxon war, keeps appearing up ahead. He chases him but can never catch him. A large glowing treasure chest also appears in these troublesome dreams. Like his father, the chest always disappears from sight just as he reaches the top of the rise when it should come into clear view. William will never sleep easily again until his father's death in Germany is avenged. And what is in that chest? Is it a holy relic that is the answer to the Celtic prayers?
IBT: Bremen falls to our Danish allies!
1260 AD: We return to Germany with a settler and 6 units. Lets hope they can hold. Were outside the Germany cultural barrio though, so I think this should work.
IBT: Try to get ROP with Danes but they wont do it since we snuck attacked England.
1263 AD: Found the Celtic Expeditionary Base in Germany. Land 8 Gaelic Warriors who head into the hills 1 tile from where we lost the Splinter. No sign of it at present.
IBT: Danes pulling back into Bremen with 2 captured catapults. Sword carrying Splinter attacks us and loses!
1266 AD: Splinter only guarded by 1 elite sword. With our all-terrain Gaelics, I should be able to rush in and pick it up. Can you seize it and move in the same turn? Not sure
Were going for it! Take it easily; and yes you can keep moving. No movement loss for seizing it. We retreat back to base, pillaging roads behind us. The Germans shouldnt be able to retake it next turn! I even bring over a Settler and found Splinterburg over top of the relic to further ensure its safety.
IBT: Magyars declare war on the Turks. Poles declare war on the Byzantines. Watch Danes capture two more catapults. Cataphracts gather 1 tile from Rennes. Are they going somewhere, or after us?
1269 AD: The Splinter is rushed home to England. A perfect place to stop. Ill let the next player decide where to proceed next. Were close to 9000 VP. By the time we get these two relics to Jerusalem, we will win. Were already at war with the Abbasids. It is time to go crusading. You might want to keep up the war with Germany for a while though. It would be nice if one of these elite units finally gave us an army to take to the Holy Land.
William Wallace has become a man. The Splinter can be united with the Holy Grail, and the Celtic quest to return them to Jerusalem begun. Time to finish up the great Bayeux Tapestry so the deeds of Wallace can be stitched into fabric for all time!
Prepare for a Crusade!
