The New Student's Reference Work/Marston Moor
Mar'ston Moor, an historic plain, seven miles west of York, England, was the scene of a great victory of the parliamentary forces on July 2, 1644 over the royalist army of Charles I in the Civil War. Twenty-two thousand royalists were led by Prince Rupert. The parliamentary troops were under the Earl of Manchester, Cromwell and Crawford, in all 15,000 foot and 9,000 horse. The royalists fled, leaving 4,000 men dead on the field. This victory gave the whole north to the parliament, and first brought Cromwell into notice. See S. R. Gardiner's History of the Civil War.
