It was formed in 1881 as part of the Childers Reforms when the 57th (West Middlesex) and 77th (East Middlesex) Regiments of Foot were amalgamated with the county's militia and rifle volunteer units. The Middlesex was one of the principal home counties based regiments with a long tradition. They inherited their nickname, the ?Die-hards?, from the 57th Regiment of Foot (West Middlesex), which later became the 1st Battalion of the Middlesex Regiment. The 57th gained the name during the Peninsular War when, at the Battle of Albuera on 16 May 1811 their commander Colonel Inglis had his horse shot from under him, severely wounded and outnumbered by the French he called to his men ?Die hard, 57th. Die hard!? "Albuhera" was the principal battle honour on the Middlesex Regiment's colours.
