The 1707 campaign was uneventful, but the regiment suffered extensively from fatigue and illness, being reduced at one point to a hundred men able to fight. In 1708 the regiment was briefly placed on notice to return to Great Britain, which was threatened with invasion, but was stood down after the French fleet was dispersed without making a landing. In July they fought at the Battle of Oudenarde, taking heavy casualties, and then served at the Siege of Lille. During the siege, they were part of a force detached to guard an ammunition convoy in late September; it was intercepted by a French force at Wijnendale, who were themselves successfully ambushed by the escorts. The French force lost six thousand killed and wounded, compared to only nine hundred of the allied force. At the very end of the year, the Cameronians were part of the force which captured Ghent, where they then remained in winter quarters.
