In the siege of Tarragona (3–11 June 1813), an overwhelming Anglo-Allied force commanded by Lieutenant General John Murray, 8th Baronet, failed to capture the Spanish port of Tarragona from a small Franco-Italian garrison led by General of Brigade Antoine Marc Augustin Bertoletti.

Murray's Anglo-Sicilian-Spanish army, based on Alicante, inflicted a sharp check on Marshal Louis Gabriel Suchet's corps at the Battle of Castalla in April.

After this action, General Arthur Wellesley, Marquess of Wellington ordered Murray to attack Tarragona, which is on the east coast of Spain.

Wellington planned to launch his summer 1813 offensive against King Joseph Bonaparte's French armies.

On 2 June Rear-Admiral Benjamin Hallowell Carew's squadron put Murray's 16,000 men ashore at Salou Bay, six miles south of Tarragona.

When he heard Tarragona was attacked, Suchet and 8,000 men began to march north from Valencia.

Mathieu brushed with Copons' outposts, found he was facing a combined army of 23,000 men and fell back northward.

By the night of 12 June the entire force was taken on board the ships, leaving the 18 siege guns spiked and many stores left behind.

When Murray heard that French soldiers were at hand he immediately ordered that his army be re-embarked, to Hallowell's disgust.

Lord William Bentinck relieved Murray of command and the thwarted expedition sailed back to Alicante.
