During the first half of the nineteenth century , Yeomanry Regiments were used extensively in support of the civil authority to quell riots and civil disturbances , including the Peterloo Massacre ; as police forces were created and took over this role , the Yeomanry concentrated on local defence . In 1827 , it was decided for financial reasons to reduce the number of yeomanry regiments , disbanding those that had not been required to assist the civil power over the previous decade . A number of independent troops were also dissolved . Following these reductions , the yeomanry establishment was fixed at 22 corps ( regiments ) receiving allowances and a further 16 serving without pay
