Successive reforms saw the smaller corps grouped into battalions with neighbouring corps, then most lost their identities when they became volunteer battalions of new county regiments 1881. These regiments typically contained two regular battalions, which had previously been separate single battalion regiments, as the first and second battalions, sharing a depot, with militia and volunteer units in the same county becoming additionally numbered battalions. As the majority of these new regiments were formed from regular line infantry and most of the volunteer rifle corps linked with them would lose their identity as rifle units. Examples included the Robin Hood Rifles, which was to become the 7th (Robin Hood) Battalion, Sherwood Foresters (Nottinghamshire and Derbyshire Regiment). The rifles identity was not always lost despite becoming part of a line infantry regiment.
