well, i did it last night, united Scandinavia, in the year of our Lord 1211.
i had my eye on Norway for some 20 years now, seeing them flip wars on and off with England, England invading Norway, Norway invading England on and on etc.
i placed troops on the border when they where off in England after getting the approval from the Pope to claim Norway as my own, and just after i had saved and was about to send the LETTER and give the order to cross the border, my king died and all hell broke loose at home since his son was too young to rule and had to go regency for a few years more, and vassals dont seem to like regents much (eh?), so i spent the following time using the troops meant for the Norway front to popamole rebellious dukes and dukettes.
well after the last rebel fell (Duke of Skåne, beheaded AGAIN) i scanned Norway how they where doing and saw they where almost defenceless, every levy was off in England and King Olaf of England had some 800 men as a occupying force in Bergen and every norwegian able to lift a spear was in Northern England, so i saved, paused, sent a "I ATAK U NAW ROFL" letter to Norway and rallied every levy i had, hired 2 mercenary armies as a extra ATK boost (fuck it, if i loose this i prob loose big time anyway), placed them in perfect surgical strike positions, from Vik to Narvik, some 15.000 men in combined raised levy and 10.000 mercenary troops, in the south targeting Vik, Oppland, Bergen and the Heartlands of Norway and the middle targeting Tröndelag and Römsdal, men from the kings own demesnes and surrounding vassals (Hälsingland, Dalarna, Västergötland, Östergötland etc) in the Swedish Heartland and a mercenary army, in the north targeting Nordland and Finnmark, savage Finnish troops with the best Swedish commanders and the second supporting mercenary army, i saved again, gave a "crack her open boys, tonight we dine in Oslo" order and un-paused.
well, the border breach went smooth, no border guards where visible, and the armies began sieging their designated targets, still unopposed.
after some weeks of free reign, i was beginning to wonder where the hell the norwegians where? are they out in the bay with some monster army on boats? i was nervously masturbating by then.
no, just the home town defenders and me, towns fell, churches fell, castles fell, north Norway fell to the Finns not even needing the mercs, in middle Norway my army was just some weeks away from reaching the ocean, south Norway was abit harder but nothing serious since the northern troops on their way south would reinforce the troops getting stuck.
then, as just Rogaland, Telemark and another province was the only ones left to take before total victory, the norwegians came home.
3025 norwegians, where i had expected close to 10.000 or more.
i PPFFFFTTT, crushed them with a merc army, then sued for peace and annexation.
if only i could create a Empire title of it all.
