The Iberian Peninsular War from 1808 to 1814, known in Spain as the Guerra de la Independencia, formed part of the Napoleonic wars, which ended with Napoleon’s abdication.

In 1808 the 10th Light Dragoons sailed to the Peninsula to assist Spain and Portugal after a French invasion, and during the retreat to Corruna fought under the command of General Sir John Moore at the Battles of Sahagun (21st December 1808) and Benevente (29th December 1808). In 1811 the 10th and 11th Light Dragoons both returned to Spain with the Duke of Wellington, for a successful campaign.
