Richard Mackinder worked at Bosworth Battlefield between 1991 and 2015. In 2001 he set up a team of volunteers called the Ambion Historical & Archaeological Research Group which aimed to find evidence of the 1485 battle and to explore human impact on the local landscape. In 2005 he became the onsite co-ordinator for the Lottery-funded project led jointly by the Battlefield Trust and Leicestershire County Council which in 2010 proved where at least part of the battle was fought. He has been guiding visitors around the battlefield for thirty years.
