These regiments volunteered for service in William's campaign in Ireland. After training on Fulwood Moor, near Preston, the Lancashire brigade, commanded by the Earl of Derby's brother, Lieutenant-Colonel the Hon James Stanley (1st Foot Guards), sailed with the army from Wallasey and landed at Carrickfergus on 14 June 1690. It played a full part in the campaign, serving in the Siege of Carrickfergus, at the Battle of the Boyne, and the Siege of Athlone. After a short tour of garrison duty in Dublin, the Lancashire brigade embarked at Howth in September to return to England to be disembodied on 15 October. Lieutenant-Colonel Stanley then recruited a number of veterans from the brigade for the regiment he was joining in Flanders. He succeeded to the command after his colonel was killed at the Battle of Steenkerque, after which the unit became 'Stanley's Regiment' (later the Bedfordshire Regiment). Colonel Stanley succeeded his brother as 10th Earl of Derby and Lord Lieutenant of Lancashire in 1702.
