Langdale attended St John's College, Cambridge in 1612 and inherited his father's estates in 1617.
His sister-in-law Katherine was the first wife of Sir John Hotham (1589–1645); in 1620, the two went to Europe and briefly fought for Elizabeth of Bohemia, sister of Charles I. Sir John was appointed Parliamentary Governor of Hull, Yorkshire in 1642 and executed for treason in 1645 along with his son John, whom Clarendon describes as a close friend of Langdale.

During the 1620s and 1630s, Langdale became an increasingly important local political figure; he was knighted in 1628 but he opposed the Forced Loan and payment of Ship money, both of which were attempts to rule without Parliament.
He was punished by being appointed Sheriff of Yorkshire in 1639, making him personally liable for any shortfalls in collecting the taxes.
He eventually complied but was removed in July 1640 after organising a petition signed by leading members of the Yorkshire gentry listing their 'grievances.'

He became a Royalist during the War of the Three Kingdoms in 1642, more from a sense of duty than conviction, and fought under the Marquess of Newcastle, Royalist commander in Northern England.
After defeat at the Battle of Marston Moor in July 1644, he formed the surviving cavalry into the "Northern Horse".
This regiment, which included the remnants of an estimated 30 others, was described as a "rabble of gentility" and quickly gained a reputation for poor discipline.

In February 1645, Langdale relieved Pontefract Castle, but the behaviour of his troops damaged the Royalist cause and without infantry support he was forced to retire, leaving the castle to be besieged once more.
In June the Northern Horse formed the Royalist left wing at the Battle of Naseby; they initially held their ground against Cromwell's more numerous and better disciplined troopers before being outflanked and driven from the field.

The survivors of Naseby, which included the Northern Horse, withdrew to Raglan Castle in South Wales, but on 10 July the last significant Royalist field army in England was destroyed at the Battle of Langport.
Langdale and other Yorkshire Royalists wanted to go north to link up with Montrose, who won a series of  victories in Scotland from 1644 to 1645.
Charles agreed but only after lifting the Siege of Chester, his last major port in the West and vital for communication with supporters in Ireland.
On 24 September the Royalists were defeated at the Battle of Rowton Heath.

News came of Montrose's defeat at the Battle of Philiphaugh on 13 September.
Langdale and Lord Digby escaped from Chester with about 2,400 cavalry, but on 15 October a Parliamentarian army intercepted and dispersed their forces at Sherburn-in-Elmet.
Digby and Langdale escaped to France and the First Civil War came to an end in June 1646.

When the Second Civil War began in 1648, Langdale returned from exile to lead the Royalists in Cumberland and seized the border town of Berwick-upon-Tweed to enable his Scottish Engager allies to invade England.
Major-General John Lambert, Parliamentary commander in the North, avoided battle, but in August was joined by Cromwell and Fairfax who had defeated Royalist risings in Wales and Southern England.
Langdale met up with the Duke of Hamilton's Scottish Engager army but they were decisively defeated by Cromwell at the Battle of Preston, over a period of three days between 17 and 19 August.

Along with much of the cavalry, Langdale and Hamilton evaded capture at Preston but were taken shortly afterwards and imprisoned in Nottingham Castle.
The Second Civil War convinced Parliamentarians, including Cromwell, that peace could only be assured by the death of prominent Royalists; Hamilton was executed, as was Charles himself in January 1649.
As one of seven Royalists excluded by name from pardon, Langdale avoided a similar fate by escaping dressed as a milkmaid and made his way to France once again.

Under the 1650 Treaty of Breda, the Scots Covenanters agreed to restore Charles II to the English and Scots thrones but insisted on the exclusion of man
