Edge′hill, a hill or ridge in Warwickshire upon which was fought the first important battle of the Civil War in England, Oct. 23, 1642.  King Charles intended to march upon London, but was met by the Earl of Essex with 10,000 of the troops of the Roundheads.  The king’s army was in number about 12,000, and was drawn up on Edgehill.  Prince Rupert, who led the right wing of the royalists, charged with his cavalry the left wing of the Roundheads and pursued it for several miles; but meanwhile the right wing of the Roundheads drove back the royal infantry with great loss.  The battle was indecisive, the royalist loss being the heavier.
