They will be holding a public talk and discussion to commemorate the Battle of Pinkie – fought between Scotland and England – at Musselburgh's Brunton Hall on Thursday, 25 March.
It is part of a campaign to make the history of the 1547 battle, held on the outskirts of the town, better known.
It was the biggest battle fought on Scottish soil and one of the most disastrous Scottish defeats, with thousands killed. Local people and historians have formed the Pinkie Battlefield Group, which aims to create a visitor trail and educational resources.
They also hope to organise an archaeological survey of the battlefield.
Dr Iain Banks, of the Centre for Battlefield Archaeology, will give a talk, while storytellers Nicola Wright and Angie Townsend will bring the human tragedy to life.
Andrew Coulson, a group member, said: "Despite this wealth of material, the events and locations of the battle are not well known."
