Tricorn is actually a more modern name for the hat established in the mid 19th Century, in the 18th Century they were more often called cocked hats or 3 cornered hats or maybe just hats
The tricorn is always worn with one of the corners pointing forward, although musket men did shift the point over one eye to help with firing their guns.
