Do they do this every year? Sounds cool and it would be closer than my beloved Monmouth.
Not this particular event, i.e. Battle of Caulk’s Field; the WSJ article says that it is funded by a grant and names different locations where the events are being held re the war on the water, Annapolis and Baltimore.
Chestertown does have a Chestertown Tea Party around the end of May, I think. It is well advertized and for Sat they have a re-enactment of throwing the tea into the harbor after political discussions through the town and to the harbor. Street theater. The town is packed with vendors and many people come from “the other side” (of the Bay Bridge.) Do a search for it for the date and schedule.
Maryland has been doing celebrations of different events in counties having to do with the war of 1812. If I can find a site for the state, I will send it to you later.
