Just ask Elsu (or near anyone for that matter but...moving on). Not only has he been shot some number of times he's also been stabbed in the upper left arm by a bayonet attached to the end of a rifle. Now this happened some time back during a fight with the French a while after they had first arrived in the Americas. The scar remains, both on the front and back of his arm (it almost hit him in the shoulder), as does his severe dislike of the second player French.
This there is no talking him out of and one grudge that will likely be held until his dying breath....
