Alexander Cannon a Scot who previously served in the Dutch Scots Brigade was appointed Colonel in August 1687. On 5 November 1688, William III landed at Torbay in the invasion later known as the Glorious Revolution and James assembled his army on Salisbury Plain to block an advance on London. However, many now changed sides; the majority of the Queen Consort's Regiment followed Lieutenant-Colonel Richard Leveson into William's camp while Cannon and his own troop remained loyal, staying with James as he retreated to London. On 31 December, Leveson replaced Cannon as Colonel and as was customary, the regiment now took his name and became "Leveson's Dragoons."
