Also, since we killed so many foes, I'm sure there are tons of empty longboats on the shoreline now.
Grab as many of those as we can crew on our return home. Try to get a few bigger ones allowing sixty or more, also, with vicious looking dragon prows! Use as few men to crew each as possible, or even pay some locals to sail them upriver. A few men can drive our horses back in a herd, though we can take our destrier on one of the larger boats.
Gather what plunder we can from enemy bodies, even if only their iron weapons. As William Marshall found out, knights who thought nothing of reward after the battle were soon impoverished. Grab a few impressively barbaric-looking standards of theirs to display in our hall. They have a baggage camp aorund here with loot from their raids, and food which may help the refugees whose harvests were interrupted.
A general sense of how costly the victory was would also be interesting. We started with 8000 men.
Might have been Spain, because I'm pretty sure France never invaded Britain. (Barring the first time, of course)
you are quite correct, however the French were never against paying others to. Especially the Scottish.
True, and the French did try directly a few times. For example, Louis, the son of Phillip Augustus, was up to some shenanigans in England around 1215, even being proclaimed king in London at one point.
