First of all I have to talk about an English Lord(of which I can't remember his name)that I met in the sea, he had only 30 men while my character, a sergent in the french army named François De Valeris, had 15 grenadier guards, so I decided to take him out. I put the cursor on him and the action description said "Running from François De Valeris's party" but he didn't move, he was somewhat stuck.
Then I attacked him and before the battle starts, the game tells me that I will face 15 units against 14 of mine(I had only 1 skill point in Tactics).
On the ships there is the already mentioned "Sailors battle". After losing many men, I won the battle and this showed up:
Then, returning to the map, he was still alive with some troops despite the game telling me he had escaped.
I attacked him a second time, but nothing changed.
I wanted to test more and I found some allies fighting a few British Lords, so I decided to join in. Apart from the already mentioned bug with cannons blocking paths(this time were the enemies' ones on our ship)I found this untextured horse:
Also, I took 2 flags from the enemy(a National colour and a Scottish regimental one)but they multiplied in the inventory:
