Well I missed that, but I'm not as up on period ships as you, so I wasn't looking that close. However, it still pretty much gives one the feeling what the average Bostonian must have felt to look out to the harbor one day in October 1768 or New York later on and see it filled with a HUGE British Fleet. "God's Bones!" (A common period and blasphemous exclamation of wonder.)
Some day Hollywood is going to give up on ALL period Artillery Shells blowing up in the air or when the Shells hit the ground. Yes, they did have Mortars with shells that did that and even Mortar Ships, but not regular or even Siege Artillery. Though it was a bit gory, at least in "The Patriot" they showed a period Artillery round shot coming towards a soldier, bouncing and then taking the Soldier's Head Off. The round shot acting that way was surprisingly period accurate.
I was pleasantly surprised they showed footage of Washington running Mount Vernon between wars. THAT was when Washington learned the basics to handle managerial problems of running an Army, though I was sad to see they missed that point.
Overall, though, I thought they did a pretty good job. Hopefully this will spur more interest in the period.
