, Royalist commander at Sourton Down|alt=A 1626 oil painting of Ralph Hopton Victory at the
Battle of Braddock Down in January 1643 secured Royalist control of Cornwall, and established Hopton as commander in the west. He wanted to attack
Plymouth, but the city could easily be reinforced by sea, and the Cornish militia refused to cross the
River Tamar into Devon. After some minor skirmishes, the two sides agreed a local truce in late February, allowing Hopton to retreat into Cornwall; this truce was greeted with incredulity by
William Waller, Parliamentarian commander in the west, who argued it primarily benefited the Royalists. Anticipating the end of the truce on 22 April, Chudleigh assembled around 1,600 troops at
Lifton, near
Launceston, where Hopton had concentrated his army. He attacked at around 10:00am the next morning, taking the Royalists by surprise, but they quickly recovered and, faced by superior numbers, Chudleigh withdrew to his base at
Okehampton. Hopton did not pursue him, noting that, as usual after a battle, his Cornish soldiers "grew disorderly and mutinous". On reaching Okehampton, some of Chudleigh's units departed, leaving him 1,000 infantry, and three or four troops of dragoons. This was interpreted as a general retreat; Hopton later recorded "there came a friend from Okehampton, who assured us the enemy was in very great disquiet and fear." Hoping to take advantage, he left Launceston with 3,000 infantry, 300
cavalry and 300 dragoons. The column was led by 300 dragoons and cavalry, then half the infantry, with their four
guns in the centre. The rest of the infantry followed, with the remaining dragoons and cavalry in the rear. They intended to stop for the night at
Sourton Down, then attack Okehampton at dawn. By chance, they were spotted by a Parliamentarian
quartermaster, who informed Chudleigh at around 9:00pm that the enemy was only away. In his subsequent report, Chudleigh complained that "by the intolerable neglect of our lying deputy Scout Master, we were surprised by the whole enemy body of horse and foot." Additionally, the artillery transport had been taken to
Crediton against his orders and, unwilling to abandon the guns saved at Launceston, Chudleigh planned a
counterattack. == Battle ==
