The only field army remaining to the King was Goring's, and though Hopton, who sorrowfully accepted the command after Goring's departure, tried at the last moment to revive the memories and the local patriotism of 1643, it was of no use to fight against the New Model with the armed rabble that Goring turned over to him. Dartmouth surrendered on 18 January 1646, Hopton was defeated at the Battle of Torrington on 16 February, and surrendered the remnant of his worthless army on 14 March. Exeter fell on 13 April. Elsewhere, Hereford was taken on 17 December 1645, and the Battle of Stow-on-the-Wold, the last pitched battle of the war, was fought and lost by Lord Astley on 21 March 1646. On 27 April Charles I journeyed from Oxford to Newark and surrendered on 5 May to General David Leslie, commander of the Scottish army besiege Newark. Newark surrendered the next day and the third siege of Oxford ended with a treaty being negotiated by Sir Richard Lane and signed on 24 June. Wallingford Castle, the last English royalist stronghold, fell after a 65-day siege on 27 July. On 31 August Montrose escaped from the Highlands. On the 19th of the same month Raglan Castle surrendered, and the last Royalist post of all, Harlech Castle, maintained the useless struggle until 13 March 1647. Charles himself, after leaving Newark in November 1645, had spent the winter in and around Oxford, whence, after an adventurous journey, he came to the camp of the Scottish army at Southwell on 5 May 1646.. How many days passed between Dartmouth's surrender and the defeat of Hopton at the Battle of Torrington?
