The Napoleonic Wars were ended with the Battle of Waterloo in 1815. The Royal East Middlesex Militia was finally disembodied in 1816. After Waterloo there was another long peace. Although officers continued to be commissioned into the militia and ballots were still held, the regiments were rarely assembled for training and the permanent staffs of sergeants and drummers were progressively reduced. 1852 Reforms The Militia of the United Kingdom was revived by the Militia Act of 1852, enacted during a period of international tension. As before, units were raised and administered on a county basis, and filled by voluntary enlistment (although conscription by means of the militia ballot might be used if the counties failed to meet their quotas). Training was for 56 days on enlistment, then for 21–28 days per year, during which the men received full army pay. Under the Act, militia units could be embodied by Royal Proclamation for full-time service in three circumstances: 1. 'Whenever a state of war exists between Her Majesty and any foreign power'. 2. 'In all cases of invasion or upon imminent danger thereof'. 3. 'In all cases of rebellion or insurrection'. As part of the 1852 reforms, the post of colonel in the militia was abolished, but existing colonels such as Thomas Wood retained their positions. Crimean War and after War having broken out with Russia in 1854 and an expeditionary force sent to the Crimea, the militia began to be called out for home defence. The Royal East Middlesex Militia was embodied at Hampstead by the beginning of February 1855, when the unit's strength was put between 600 and 700 men. The regiment moved to Aldershot by the beginning of June. Here it spent the period of its embodiment, returning to Hampstead by February 1856 and being disembodied by April. Although the 4th and 5th Middlesex Militia were embodied in 1857 to relieve regular troops for service against the Indian Mutiny, the number of regiments required was smaller, and the Royal East Middlesex were not called upon. Thereafter the militia regiments were called out for their annual training. Colonel Wood camped with his regiment at Aldershot in his 80th year. After Wood's death in 1860 his lieutenant-colonel (since 1850), Thomas St Leger Alcock, formerly a major in the 95th Foot, continued as lt-col commandant. Alcock became the regiment's first Honorary Colonel in July 1871 and was succeeded in the command
