In September 1808, the 2nd battalion was transferred to join Lieutenant General Sir John Moore's command. Along with the rest of the 15,000 men, the 2nd battalion was destined for Corunna where it took part in Moore's campaign in northern Spain during the winter of 1808 to assist the Spanish Armies against Imperial France. It retreated with the rest of Moore's forces to Corunna. On 16 January 1809, as part of Lieutenant-General David Baird's division guarding the right flank of the British forces, the 2nd battalion fought in some of the heaviest fighting of the battle. The 2nd battalion advanced in support of the 42nd Regiment of Foot and the 50th Regiment of Foot. Despite being driven back from their initial gains, the 2nd battalion counter-attacked with the 42nd and 50th regiments and then held their position until relieved. With the surviving units of Moore's army, the 2nd battalion was withdrawn by sea to England the next day. For their part in the battle, the regiment was granted the battle honour "Corunna".
