In February 1851 he became an equerry to the Duke of Cambridge. During the Crimean War Paulet served as Assistant Adjutant-General of the Cavalry Division, under Lord Lucan, earning promotion to brevet colonel on 20 June 1854. He fought at the Battle of Alma in September 1854, at the Battle of Balaklava in October 1854 and at the Battle of Inkerman in November 1854 as well as at the Siege of Sevastopol which was on-going at that time. He was then given command of the rear area, including the Bosphorus, Gallipoli and the Dardanelles, with promotion to the substantive rank of lieutenant colonel on 28 November 1854 and to the local rank of brigadier-general on 19 January 1855: in this capacity he gave his support to Florence Nightingale in her efforts to modernise medical support in the field.
