Cause → Event → Consequence
During the summer of 1644, Covenanter and Parliamentarian forces besieged York. Prince Rupert assembled an army, marched through northwest England gathering reinforcements, and crossed the Pennines to relieve the city. This convergence of large opposing forces made a major engagement inevitable.
On 2 July 1644, Royalist forces under Prince Rupert and the Marquess of Newcastle faced the combined Parliamentarian and Scottish Covenanter armies on Marston Moor. A surprise evening attack by the allied forces led to a two-hour battle in which Oliver Cromwell's cavalry routed the Royalist horse, and the remaining Royalist infantry was annihilated.
The Royalists abandoned Northern England, losing manpower from strongly Royalist northern counties and access to the European continent via North Sea ports. Though they recovered partially with victories in southern England later in 1644, the loss of the north proved fatal in 1645 when they failed to link up with the Scottish Royalists under the Marquess of Montrose.
