Britain added six new regiments between 1 December 1823 and 25 March 1824, the 94th to 99th Regiments.

Each regiment originally had about half of the officers taken from the half-pay list. So a bit of a savings to the government.

The three Royal Veteran Battalions raised 25 December 1821 were reduced in 1826, two in April and one in June.
