Parliamentarians Win Battle of Marston Moor
By mid-1644, the English Civil War had raged for two years with Royalist forces under King Charles I holding advantages in several regions. In the north, a combined Parliamentarian and Scottish Covenanter army besieged the Royalist-held city of York. Prince Rupert of the Rhine led a relief force to break the siege, clashing with the besiegers on open ground near Long Marston on the evening of July 2. Oliver Cromwell’s cavalry played a decisive role in routing the Royalist horse, leading to a crushing defeat for the king’s supporters. The battle, one of the largest fought on English soil, resulted in heavy Royalist casualties and the loss of much of their northern army.
