In March 1919, ''St Vincent'' was reduced to reserve and became a gunnery training ship at [[HMNB Portsmouth|Portsmouth]]. She then became flagship of the [[Reserve Fleet (United Kingdom)|Reserve Fleet]] in June and was relieved as gunnery training ship in December, when she was transferred to Rosyth. There she remained until listed for disposal in March 1921; she was sold for scrap on 1 December 1921 and demolished.<ref name=b86/>

In January 1919, ''Collingwood'' was transferred to Devonport and assigned to the Reserve Fleet. Upon the dissolution of the Grand Fleet on 18 March, the Reserve Fleet was renamed the Third Fleet and ''Collingwood'' became its flagship. She became a [[Ship's tender|tender]] to [[HMS Vivid (shore establishment 1890)|HMS ''Vivid'']] on 1 October and served as a gunnery and [[wireless telegraphy]] training ship until early August 1920, when the ship returned to the reserve.

Much of ''Vanguard''{{'}}s wreck was salvaged before it was declared a war grave in 1984. The amidships portion of the ship is almost completely gone and 'P' and 'Q' turrets are some {{convert|40|m}} away, presumably blown there by the magazine explosions. The bow and stern areas are almost intact as has been revealed by a survey authorised by the [[Ministry of Defence (United Kingdom)|Ministry of Defence]] in 2016 in preparation for the centenary commemoration planned for 2017.<ref name="RNex">{{cite web |title=New Light is Shed on Disastrous Royal Navy Explosion in Scapa Flow |date=20 January 2017 |url=http://navaltoday.com/2017/01/20/new-light-is-shed-on-disastrous-royal-navy-explosion-in-scapa-flow/ |publisher=Naval Today |access-date=29 January 2017}}</ref><ref>{{cite news |title=Scapa Flow Divers Reveal New Images of HMS Vanguard Wreck |url=http://www.express.co.uk/news/world/756218/hms-vanguard-warship-scapa-flow-ministry-of-defence |access-date=29 January 2017 |publisher=Express Newspapers |date=19 January 2017|language=en}}</ref><ref>{{Canmore |desc=HMS Vanguard: Scapa Flow, Orkney |num=103004 |access-date=29 January 2017 }}</ref> The wreck was named a controlled site in 2002 and cannot be dived upon, except with permission from the Ministry.<ref>{{cite web |title=The Protection of Military Remains Act 1986 (Designation of Vessels and Controlled Sites) Order 2002 |url=http://www.legislation.gov.uk/uksi/2002/1761/article/3/made |publisher=The National Archives|access-date=29 January 2017|language=en}}</ref>
