New Yorkers got the chance to experience history at the Battle of Brooklyn Day at Green-Wood Cemetery on Sunday.

“You can really step out of your world for at least a few moments,” History at Play founder Judith Kalaora said.

History at Play is a performance troop. Kalaora and her colleagues are experts in the details of what life was like 248 years ago: from the music to the military ware and uniforms.

“Those middle battles, those battles that really start here in New York, really are the beginnings of the American Revolution,” Kalaora said.

Historians say the Battle of Brooklyn, fought at Green-Wood Cemetary, was a pivotal part of the Revolutionary War.

The Battle of Brooklyn was the first battle fought after the signing of the Declaration of Independence — a difficult time for the Continental Army. The British defeated them and gained control of an important resource: the port of New York.

“This port of New York, which is vital: from receiving supplies, receiving reinforcements, keeping up correspondences with other colonies,” Kalaora said.

Organizers hope visitors can soak up the history and gain an appreciation.

“I love the ability where we have this open space where we can bring together so many cultural institutions, so many folks who are passionate about the American Revolution,” Green-Wood director of education Rachel Walman said.

Attendees shared the pieces of history they took away from the event.

“We are learning a lot. We learned about flags from the Battle of Brooklyn. We are learning about classic toys from that era,” Michelle Fresca said.

Organizers said the annual event has been going on for around 20 years and attendance is free.

The original Battle of Brooklyn was fought on Aug. 27, 1776.
