By 1795 Lumley had transferred to the 22nd Dragoons as lieutenant colonel and in 1798 was sent to Ireland to help defeat the United Irishmen forces during the Irish Rebellion of 1798 . During this conflict , Lumley used his regiment for patrolling the countryside and on 7 June 1798 was at Antrim when the town was attacked by at least 4 , 000 rebels led by Henry Joy McCracken . The town was defended by a mixture of regular soldiers , militia and loyalist volunteers who made their stand at Antrim Castle , Lumley commanding the cavalry .

During the opening stages of the Battle of Albuera on 16 May 1811 , Lumley replaced Robert Ballard Long in command the Allied cavalry by order of Sir William Beresford because of Long ' s alleged incompetence , though other reasons were given at the time . During the battle , Lumley ' s cavalry supported the Allied right after Daniel Hoghton ' s brigade was destroyed and then supported the flanks of Beresford ' s main assault in the final stages of the action . A few days later , Lumley was again engaged in a cavalry action at the Battle of Usagre , where two French cavalry regiments were neatly trapped and almost destroyed , but his health was failing and in August 1811 he was invalided home , never to see action again .
