The Battle of Winwick (also known as the Battle of Red Bank) was fought on 19 August 1648 near the Lancashire village of Winwick between part of a Royalist army under Lieutenant General William Baillie and a Parliamentarian army commanded by Lieutenant General Oliver Cromwell. The Royalists were defeated with all of those who took part in the fighting, their army's entire infantry force, either killed or captured. The Royalist mounted component fled but surrendered five days after the battle. Winwick was the last battle of the Second English Civil War.

The First English Civil War between Royalist supporters of Charles I and an alliance of Parliamentarian and Scottish forces ended in 1646 with Charles defeated and a prisoner. He continued to negotiate with several factions among his opponents and this sparked the Second English Civil War in 1648: a series of mutinies and Royalist uprisings in England and Wales, and a Scottish Royalist invasion of north-west England. The invading army was attacked and defeated by a smaller Parliamentarian army at the battle of Preston on 17 August. The majority of the Royalists, mostly Scots, had not been engaged but they fled south, closely pursued by the Parliamentarians, mostly of the New Model Army. On 19 August, hungry, cold, soaking wet, exhausted and short of dry powder, the Scottish infantry turned to fight at Winwick. Their cavalry waited away at Warrington.

The Parliamentarian advance guard was put to flight with heavy casualties. After a lengthy pause, Parliamentarian infantry arrived: they attempted to storm the Scottish position and were thrown back. A full-scale assault was then launched which resulted in more than three hours of furious but indecisive close-quarters fighting. The Parliamentarians fell back again, pinned the Scots in place with their cavalry and sent their infantry on a circuitous flank march. As soon as the Scots saw this force appear on their right flank they broke and fled. Parliamentarian cavalry pursued, killing many. All of the surviving Scots surrendered: their infantry either at Winwick church or in Warrington, their cavalry on 24 August at Uttoxeter. Winwick was the final battle of the war. In its aftermath Charles was beheaded on 30 January 1649 and England became a republic on 19 May.

Primary sources The three most useful accounts of the short campaign which included the battles of Preston and Winwick were written by Oliver Cromwell, commander of the Parliamentarian army; Marmaduke Langdale, commander of the English Royalists who bore the brunt of the fighting at Preston; and John Hodgson, a lieutenant in a Parliamentarian infantry regiment. The first two accounts were written shortly after the campaign; Hodgson wrote his memoirs in 1683. Cromwell was the only one of the three present at Winwick. There is also a letter by the Parliamentarian cavalry officer Major John Sanderson giving details of his participation in the battle and an account of it written by the Royalist James Heath in 1661. Two partial accounts of the campaign were written by senior Scottish commanders in the 1670s.

Opposing forces Infantry Infantry formations, equipment and tactics were similar in both armies. The basic tactical formation was the regiment, which varied greatly in size. An infantry regiment was usually made up of 10 equally sized companies and typically had a nominal or establishment strength of 800 or 1,000 men; this was rarely met. Each was composed of both musketmen and pikemen.

The musketmen were armed with muskets possessing barrels and, mostly, matchlock firing mechanisms. These relied on the glowing end of a length of slow match, thin cord soaked in saltpetre, igniting the weapon's priming powder when the trigger was pulled. They were reliable and robust weapons, but their effectiveness was severely reduced in poor weather. Keeping the slow match burning at all times resulted in the consumption of a vast amount of it, while dousing it rendered the musket useless. Balancing combat readiness against logistical capability called for fine judgement from a regiment's officers. A few musketmen on each side were equipped with the more reliable flintlock muskets. In 1648 musket tactics were in transition from firing one rank at a time so as to maintain a steady fire, to the entire unit discharging a volley simultaneously for shock effect. A well-trained musketman took approximately 40 seconds to reload and would carry ten rounds of ammunition.

Pikemen were equipped with pikes: long wooden shafts tipped with steel points. Pikes as issued were normally , but on the march they were commonly cut down to a more wieldy or so. The pikemen carried basic swords and typically wore steel helmets but no other armour; in some regiments a few pikemen, usually those in the front rank, would have also worn body armour. Military manuals of the time suggested a ratio of two musketmen for each pikeman, but in practice commanders usually attempted to maximise the number of musketmen and a higher ratio was the rule.

Both armies organised their infantry regiments into brigades of three regiments each, which doctrine suggested be deployed two regiments abreast, with the third behind as a reserve. The men in each unit would form up four or five ranks deep and in a relatively loose formation, with about of frontage per file; so an infantry regiment of 600 might form up 120 men wide and 5 deep, giving it a frontage of and a depth of . The pikemen would be placed in the centre of a formation, in a "stand", with the musketmen divided on each side. The usual tactic against infantry was for the musketmen to fire on their opponents and once it was thought they had been sufficiently weakened or demoralised the stand of pikemen would advance, attempting to break through the enemy centre. This was known as a "push of the pike". The musketmen would also advance, engaging the enemy with their musket butts, which were steel-plated for this purpose, and attempting to envelop the opposing formation.

Against cavalry, doctrine called for infantry units to tighten the spacing between their files so that each man took up only frontage and to advance steadily. To be effective against infantry, cavalry needed to break into their formation, and if the men were packed together this was not possible. It was accepted that so long as the morale of the infantry held, cavalry could do little against the front of such a formation. However, the flanks and rear were increasingly vulnerable when the infantry packed more closely together, as this made manoeuvring or turning the unit more difficult.

Cavalry

Most of the Parliamentarian cavalry were mounted on large, for the time, horses. The cavalrymen all wore metal lobster-tailed pot helmets which protected the head and, usually, the neck, cheeks and, to an extent, face; and thigh-length boots. Body armoura cuirass (metal chest and back plates)was worn by most cavalrymen, although many relied on just a jacket of thick uncured leather. They were each armed with two pistols and a sword. The pistols were long and had a very limited effective range. Most but not all cavalry pistols had flintlock firing mechanisms, which were more reliable in damp or windy weather than matchlock mechanisms. Flintlock mechanisms were more expensive than matchlock ones and were usually reserved for the cavalry, who found igniting and using the slow match while controlling a horse inconvenient. The swords were straight, and effective at both cutting and thrusting.

The Royalist cavalry were similarly equipped with helmets, pistols, swords and body armour, although many of the Scots bore lances rather than pistols. Scottish horses were smaller and lighter than their English equivalents; this gave them greater manoeuvrability but put them at a disadvantage in a face-to-face confrontation. The Scottish cavalry were well mounted, but inexperienced and ill disciplined. Parliamentarian cavalry were trained to advance very close together, with their riders' legs interlocked, at no faster than a trotto maintain formation. They would discharge their pistols at very short range and upon coming into contact attempt to use the sheer weight of their mounts and the mass of their formation to force back their opponents and burst through their ranks. Royalist cavalry were more likely to charge at a faster pace and in a looser formation.

Both armies contained dragoons. These had originated as mounted infantry, using horses to increase their operational mobility and dismounting to fight with pikes or muskets. By 1648 they had largely become specialist mounted troops; none carried pikes. The Parliamentarian dragoons were in the process of exchanging their muskets for carbines (shorter-barrelled versions of muskets, more wieldy for carrying on, or even firing from, horseback) or, occasionally, pistols. Scottish dragoons were also partway through this transformation and carried both matchlock muskets and cavalry swords. Dragoons usually acted as scouts, or formed their army's rearguard.

Artillery

Cannonballs believed to have been found at the site strongly suggest that at least one piece of light artillery was deployed.

Summary Most of the Parliamentarian soldiers were seasoned veterans, well trained and with experience of battle. The Scots as a whole were unenthusiastic about another round of warfare and had difficulty raising troops. Some regiments had barely half their establishment, of whom more than half were new recruits, lacking both experience and adequate training. A contemporary exaggerated that "not a fifth man could handle a pike."

Background

In 1639, and again in 1640, Charles I, who was king of both Scotland and England in a personal union, went to war with his Scottish subjects in the Bishops' Wars. These had arisen from the Scots' refusal to accept Charles's attempts to reform the Scottish Kirk to bring it into line with English religious practices. Charles was not successful in these endeavours and the ensuing settlement with his Scottish Parliament in 1641 severely limited his powers. After years of rising tensions the relationship between Charles and his English Parliament broke down, starting the First English Civil War in 1642.

In England Charles's supporters, the Royalists, were opposed by the combined forces of the Parliamentarians and the Scots. In 1643 the latter pair formed an alliance bound by the Solemn League and Covenant. After four years of war the Royalists were defeated and Charles surrendered to the Scots on 5 May 1646. The Scots agreed with the English Parliament on a peace settlement which would be put before the King. Known as the Newcastle Propositions, the Scots spent months trying to persuade Charles to agree to them but he refused. The Scots eventually handed Charles over to the English Parliamentary forces in exchange for a financial settlement and left England on 3 February 1647.

Charles then engaged in separate negotiations with different factions. Presbyterian English Parliamentarians and the Scots wanted him to accept a modified version of the Newcastle Propositions, but in June 1647 a junior army officer seized Charles and the army council pressed him to accept the Heads of Proposals, a less demanding set of terms. He rejected these as well and instead signed an offer known as the Engagement, which had been thrashed out with the Scottish delegation, on 26 December 1647. Charles agreed to confirm the Solemn League and Covenant by Act of Parliament in both kingdoms, and other conditions, in return for the Scots' assistance in enforcing his claim to the English throne.
