A thirst for expanding and sharing knowledge

The momentous events of 18th June 1815 still shape the world we enjoy today. Mercer’s famous 'Journal of the Waterloo Campaign' is the most quoted primary source material of the battle, much admired and debated by historians and enthusiasts. Yet in his home City of Exeter, Mercer is virtually unknown. Our work aims to widen knowledge and understanding, protecting his legacy, locally and globally, for the next 100 years.
