The first battle between European nations has happened! yet, Historical Enemies in, Unlikely situation!
While most european nations are sending massive armies to the crusades, there is one that isn't. This un-holy nation is the Kingdom of Scotland, as most of the English and Norwigen forces are going to crusading targets, Scotland has been rallying troops with out the holy cross over their heads, Assassins were found at the border towns. As england prepares for the worst, and calls in the reserves from newly conquered Ireland, fearing their would be a 2nd war in the British Isles.
The Norwigions were getting ready to launch yet another crusde army from it's capital, Though, a coastal watch tower picks up a very small navy near their shores. As it does not have the cross over their head, they took it for only one sign, an Invasion. The Norwegions would have been doomed if they had let the army come ashore, as their land defenses was weak, but they called help from the navies around, as it is mainly a sea power, Though, just receiving words by their allies, the Danes that they were going to help the Teutonic Order with their horribly failed crusade, the Scottish navy was saved from total destruction, along with it's crew.
Though as it is, This almost possibility of War, is very bad for the Norwegians and the Scotlanders.
