I'll jump in.
One hates to put one element of the Canadian Armed Forces against another. I would say the battles that happened at sea are out of sight and, to some degree, out of mind. I hate to put it this way. One of the luxuries that a soldier may have is to go back and visit the ground he once fought on, to remember and relive what happened there and to really mark hallowed ground. It's a very difficult thing, and another thing for a sailor to do that. There is no place to go; it's out at sea.
That's where monuments like Sackville allow sailors to come to some place. As Sammy said, it's a place to gather. The sailor's monument in Point Pleasant Park is exactly that way.
