At the critical [[Battle of Naseby]] in June 1645, the [[New Model Army]] smashed the King's major army. Cromwell led his wing with great success at Naseby, again routing the Royalist cavalry. At the [[Battle of Langport]] on 10 July, Cromwell participated in the defeat of the last sizeable Royalist field army. Naseby and Langport effectively ended the King's hopes of victory, and the subsequent Parliamentarian campaigns involved taking the remaining fortified Royalist positions in the west of England. In October 1645, Cromwell besieged and took the wealthy and formidable Catholic fortress [[Basing House]], later to be accused of killing 100 of its 300-man Royalist garrison after its surrender.{{Sfn|Kenyon|Ohlmeyer|2000|p=141}} He also took part in successful sieges at [[Bridgwater]], [[Sherborne]], Bristol, [[Devizes]], and [[Winchester]], then spent the first half of 1646 mopping up resistance in [[Devon]] and [[Cornwall]]. Charles I surrendered to the Scots on 5 May 1646, effectively ending the [[First English Civil War]]. Cromwell and Fairfax took the Royalists' formal surrender at [[Oxford]] in June.<ref name=bcw/>
