Hostilities had begun when King Charles I had effectively declared war by raising his standard at Nottingham on August 22, 1642, the first battle was on September 23 of that year at Powick Bridge.

Naseby was one of the last 12 battles of English Civil War, it gave Cromwell's New Model Army one of its first victories. And it marked the beginning of the end for the royal cause. There would be another 9 months of war and another 11 battles yet to fight the last of which was the Battle of Stow-on-the-Wold on March 21, 1646. The civil war did however transform both the army and navy of Britain into a professional force. This ultimately gave Britain the ability to forge an Empire that spanned the world. The conflict also awakened the political desires of the people of England giving birth to political groups such as the Levellers and Diggers. These groups in their turn had greater influence. The writings they left behind were to inspire Karl Marx* and the birth of Communism.

• The battle began around 9am and was to last until just after noon.

Battle Positions

• The Royalist lines were approximately 1.5 miles wide, on the right and drawn up against the Sulby Hedges were Prince Rupert's cavalry with an estimated strength of 2,000 to 3,000. In the center were three divisions of foot. And on the left was Sir Marmaduke Langdale and 1,500 "Northern Horse", with the Clipston to Naseby road to their left. Prince Rupert and his cavalry division took position the right.
• The Parliamentary lines were almost 2 miles wide. Their forces were drawn up on Naseby ridge. Sergeant-Major General Sir Philip Skippon took the center and left of parliaments line. His command consisted of 8 foot regiments, 5 of which were placed in the front line and 3 held in reserve, along with 2 companies of Harleys regiment of foot commanded by Lieutenant Colonel, Pride. The cavalry under the command of Ireton formed up facing Prince Ruperts horse. Cromwell's horse took position face the Royalist horse under the command of Langdale.

The Battle Begins

• Initially the battle went well for the royalist army, at one point they managed to push the parliamentary forces back. This was short lived as the parliamentary dragoons using Sulby hedges for cover opened fire on Rupert's cavalry and caused some havoc on the royalist right.
• After a brief exchange of musket fire the foot forces in the front lines clashed and soon dissolved into hand to hand fighting with swords and club musket*. The impact of Royalist charge caused the Parliament foot to slowly fall back>. Ireton's horse charged to meet the Rupert's advance, the royalist charge was turned, Ireton then split his force leading part of his cavalry to the aid of the hard pressed parliamentary foot. This was unsuccessful and Ireton was wounded* and taken prisoner. The remainder of his troop were driven from the field by Ruperts horse*.

Cromwells Attack

• Cromwell waited as Langdale's regiment of horse held position in front of woodland. Cromwell thus decided to wait, finally Langdale advanced uphill to engage Cromwell. Cromwell ordered half his command to attack Langdale, sweeping the royalist horse from the field. Cromwell dispatched a force in pursuit of Langdale and turned his attention on the royalist southern flank. At the same time Oakey's dragoons and the survivors of Ireton's cavalry attacked the royalist western flank.
  

The Royalist Collapse

• The Royalist foot had been held by the larger force of General Sir Philip Skippon. And it was soon under attack on three sides. Some were commanded to lay down their arms. The rest attempted to fall back to Dust Hill. Prince Rupert's regiment, the Bluecoats bravely covered the retreat. Ruperts Bluecoats were overwhelmed on the third assault by Skippons forces. Prince Rupert finally managed to rally his cavalry however it was too late as the royalist army was by then, in full retreat.
  

Result

• Casualties Parliament losses 460. ---
  Royalist losses 1,000.
• Of the remaining Royalist forces 4,500 surrendered and 3,000 fled the field. Most of those who escaped had horses, that meant most of the senior officers and the cavalry brigades. All field ordinance was lost to the parliamentary forces.
• A potential atrocity was recorded here. Around 500 royalist camp followers mostly women were trapped in a nearby churchyard. They were put to the sword by the pursuing parliamentary cavalry. The reason given for this was, the troops had assumed they were Irish. The cavalry involved received no punishment for this "error".
• The Royalists lost their last main field army, there were other forces available to the royal cause, however they were committed to garrison duties in Royalist held towns. This defeat was to prove the mortal blow to the royalist cause. As the remaining royalist forces were now static defending towns and other strongholds, the parliamentary forces took the towns one by one.

Important Notes

• Foot troops of the period were predominantly pike and musket the approximate average ratio on the battlefield at this time was 75% Pike to 25% Musket.
• Owing to the lack of accurate records of the time the numerical size of the forces is only approximate. Although representative and is therefore must not be regarded as accurate.
