The Civil War of the 1600s was fought between people who supported King Charles I (Royalists) and people who supported England’s Parliament (Parliamentarians). 






Britain and Ireland

Known for

The war involved Cornish, English, Irish, Scottish and Welsh people. Most Cornish people supported King Charles, but sometimes members of the same family supported different sides. Several important battles were fought in Cornwall.

Reasons for the war

King Charles I believed that he had a right to govern Britain without the help of a parliament. Between 1629 and 1640, the king did not summon (bring together) Parliament. However, Charles needed to raise money to help him rule, and without Parliament this was very difficult to get. 

King Charles’ attempts to raise money without summoning Parliament caused a lot of anger in England. His religious changes also angered people in Scotland. Relations between the king and Parliament grew worse until war broke out in August 1642.

Why did Cornwall support the king?

The Duchy of Cornwall and Cornwall’s Stannary Parliament were strongly connected with the royal family. They gave Cornwall a sense of independence, which was threatened by Parliament. In fact, during the Civil War, the Parliamentarian army set fire to the Duchy Palace and burnt the records of the Duchy of Cornwall and the Cornish Stannary Parliament.

Also, Cornish people were conservative – which meant that they did not like change. Although they were no longer Catholic, the Cornish still enjoyed parish feasts and cared for their holy wells and crosses. Many of Parliament’s supporters were strongly Protestant and disliked feasts, wells and crosses. During the Civil War, Parliament made celebrating feasts and erecting maypoles illegal. Parliamentarian soldiers also vandalised Madron’s holy well and some Cornish churches. 

The Parliamentarians had a strong English identity. People in Cornwall saw this as a threat to their own Cornish culture and identity. 

In this church the effects of their brutality are still to be seen; the timber that supports the roof is in many places burnt. The tower upon the western side is much shattered by the cannon from Stamford Hill Reverend Anthony Moore writing in 1753 about the damage done to Stratton Church by Parliamentarian soldiers

Divided families

Most of Cornwall’s leading families supported King Charles. These included the families of Basset, Coryton, Courtenay, Edgcumbe, Grenville, Rashleigh, Trelawny, Tremaine, Trevanion and Vivian. Members of these families were given the rank of colonel, major or captain in the Cornish Royalist army. However, some Cornish families such as Arundell, Carew, Godolphin and St Aubyn were divided, with some members supporting King Charles and other members supporting Parliament.

22nd August: War breaks out

Disagreements between King Charles I and Parliament led to the outbreak of the Civil War. Some people in Cornwall took Parliament’s side, but many more Cornish people sided with the king. 


19th January: Battle of Braddock Down

Early in 1643 a battle was fought at Braddock Down, near Liskeard. A brave charge led by Cornish Royalist Sir Bevil Grenville made the Parliamentarians flee the battlefield. Two hundred Parliamentarians were killed, 1,250 were taken prisoner and two large cannon were captured by the Royalists. Only two Royalist soldiers died in the battle.

Parliamentarian troops once again invaded Cornwall and camped on a hill at Stratton, near Bude. The Cornish Royalist army attacked them from four directions, pushing up the hill. The battle lasted all day. Although outnumbered, the Royalists won and forced the Parliamentarians over the border into Devon. 

18th May - Dearest Soul, praise God everlastingly…Ring out your bells. Raise bonfires. We march to meet our victorious friends and to seize all the rebels left if we can find such living. Sir Francis Basset to his wife Anne following the Royalist victory at Stratton

5th July: Battle of Lansdowne

The Cornish Royalist army left Cornwall to fight the Parliamentarians at Lansdowne, near Bath in Somerset. The Royalists once again had to fight uphill to attack the Parliamentarians. The battle was long and very bloody, with many Cornish soldiers killed. Sir Bevil Grenville was injured in the battle and later died from his injuries.  

When I came to the top of the hill, I saw Sir Bevil Grenville’s stand of pikes, which certainly preserved our army from a fatal rout with the loss of his most precious life…the air was so darkened by the smoke of the powder, that for a quarter of an hour together there was no light seen but what the fire of the volleys of shot gave Richard Atkyns writing about the death of Sir Bevil Grenville

26th July: The storming of Bristol

The Cornish Royalist army stormed and captured the city of Bristol. It was a great victory for the Cornish but their colonels John Trevanion and Sir Nicholas Slanning were killed during the fighting.

7th September: Exeter captured

The city of Exeter surrendered to the Cornish Royalist army.

10th September: King Charles’ letter of congratulations

The king sent a letter thanking the Cornish for their support and for fighting for him. The letter was placed in every church and chapel in Cornwall. Some churches in Cornwall still display the letter today.

We are so highly sensible of the extraordinary merit of Our County of Cornwall, of their zeale for the Defence of Our Person, and the just Rights of Our Crown, of their great and eminent Courage and Patience King Charles I’s letter to the Cornish (September 1643)

17th August: Surrender of Pendennis Castle

Colonel John Arundell refused to surrender Pendennis Castle at Falmouth until August 1646. This was one of the last castles held for King Charles to surrender during the Civil War. 

18th March – Sir, The Castle was committed to my government by His Majesty, who by our laws has the command of the castles and forts of this Kingdom...I resolve that I will here bury myself before I deliver up this castle to such a fight against His Majesty Colonel John Arundell to Sir Thomas Fairfax of the Parliamentarian army (1646)


16th-24th May: The Gear Rout

Although Cornwall’s Royalists had surrendered, risings took place at Penzance and Gear, near Helston, in 1648. The Parliamentarians defeated both risings. To show that Cornish resistance had been crushed, Parliamentarian soldiers marched through Penryn with Cornish hurling balls stuck on the ends of their swords.


23rd May: Surrender of the Isles of Scilly

Possession of the Isles of Scilly had changed during the Civil War. By 1648, the Royalist army had control and Sir John Grenville (the son of Sir Bevil Grenville) was put in charge. Sir John attacked Parliamentarian and Dutch ships that sailed close to the islands. The Dutch declared war on the Isles of Scilly. In April 1651, Parliamentarian soldiers and sailors stormed the islands and Sir John surrendered on 23rd May. The Isles of Scilly did not sign a peace agreement with the Dutch until 1986 – making this the longest war in history!
