On December 4, 1619, a group of 35 settlers, led by Captain John Woodlief, arrived at Berkeley Plantation in Virginia, from Bristol, England.
On the banks of the James River the Englishmen proclaimed:
“We ordaine that the day of our ship’s arrival at the place assigned for plantation, in the land of Virginia, shall be yearly and perpetually keept holy as a day of Thanksgiving to Almighty God.” 
Do you need well-behaved horses as
part of the event? I have 2 that would be perfect and are bombproof. BTW, we were part of a revolutionary war militia re-enactment in MASSACHUSETTS for Patriot’s Day (Revere’s ride) so we have experience.
