The exhibition, which recounts the story of the Yeomanry, can also be seen as part of the tour through Dalemain. This volunteer corpse, comprised of many local families, was raised in 1819 to prevent civil unrest in the absence of an effective police force. They were called upon to quell Chartist riots and fought in the Boer War before serving in the Great War. The Hasell family, owners of Dalemain House, have served in the Yeomanry from the start and one of the troops of cavalry was the Dalemain Troop. Colonel Edward Hasell commanded the regiment for many years and his grandson Captain Edward Hasell served throughout the Great War.
Located in the base of the Norman Pele-Tower the museum contains many mementoes and relics of the Westmorland & Cumberland Yeomanry as well as the two volunteer forces that preceded it – the Westmorland East and West Wards Local Militia and Cumberland Loyal Leath Ward Volunteers. Access to the Yeomanry Collection is included in the entry fee for the House and Gardens.
