 The regiment was mobilised to keep the peace on a number of occasions, such as its service at Derby in October 1831; workers in the city had rioted after the Reform Bill was rejected by the House of Lords, and the yeomanry was called in to help the regular army and the Derbyshire Yeomanry maintain order.The regiment was renamed for Prince Albert, the Prince Consort, in 1844.The Yeomanry was not intended to serve overseas, but due to the string of defeats during Black Week in December 1899, the British government realized they were going to need more troops than just the regular army.
