In 1678, concerns over the Catholic James succeeding Charles resulted in the Popish Plot, in which over 100 people were falsely accused of conspiracy to murder Charles; 22 were executed and this was followed by the 1678-1681 Exclusion Crisis. At the same time, the end of the Franco-Dutch War led to Dumbarton's regiment being discharged from the French army in June 1678; in January 1679, it was reformed and listed on the English military establishment as the 'First Foot.' This was a temporary response to the unsettled political climate and to reduce Parliamentary scrutiny, the regiment was sent to Ireland in 1680, part of it also joining the Tangier Garrison.
