1707
In April, 1707, Patrick Lord Polwarth was appointed colonel of the regiment, in succession to the Marquis of Lothian, who was removed to the colonelcy of the Scots foot guards.
1708
The king of France having fitted out a fleet and embarked troops in the early part of 1708, for the invasion of Britain by the Pretender, Lord Polwarth's regiment was held in readiness to take the field at a moment's notice, and the establishment was augmented to fifty-four men per troop; but the French fleet was driven from the Scottish coast, and the country was preserved from the horrors of civil war.
1709
In October, 1709, Lord Polwarth was succeeded in the colonelcy by William Kerr, brother of the duke of Roxburgh.
1710
1711
The gallant achievements of the forces under the great duke of Marlborough had, in the mean time, removed the theatre of war from the frontiers of Holland to the confines of France; Louis XIV. assembled an immense army to preserve the interior of his kingdom from the power of his opponents; and Queen Anne sent additional corps to the scene of contest. Kerr's dragoons were selected to proceed to the Netherlands; their establishment was augmented, in March, 1711, to sixty men per troop; and in the same month they embarked at Leith, but were driven back to the Frith and detained by contrary winds until the end of April, when they sailed for Holland.
Having been detained by the weather, the regiment did not arrive until the army had taken the field, and the men and horses had suffered by being so long on board of ship; they consequently remained in Holland for a short time in quarters of refreshment, and afterwards commenced their march for the frontiers; but when passing through Brabant, they were ordered to halt at Brussels. The regiment appears to have remained in reserve during the campaign of this year.
