From Tardis Wiki, the free Doctor Who reference
Marston Moor, only a few miles west of York and east of Crook Marsham.
In 1644, Marston Moor was the site of a major battle in the English Civil War between the forces of Oliver Cromwell and the army of Rupert. (PROSE: Nightshade, The Roundheads) During this battle, Arthur Kemp was killed by a Roundhead musket ball. (PROSE: The Roundheads)
Behind the scenes
Since in December 1648, Frances Kemp told Polly Wright that her brother Arthur had been dead for four years, (PROSE: The Roundheads) it can be inferred that the battle took place in 1644.
