Convention of Cintra

The Convention of Sintra was an agreement signed on 30 August 1808, during the Peninsular War. By the agreement, the defeated French were allowed to evacuate their troops from Portugal without further conflict. The Convention was signed at the Palace of Queluz, in Queluz, Sintra, Estremadura.

The French forces under Jean-Andoche Junot were defeated by the Anglo-Portuguese forces commanded by Sir Arthur Wellesley at Vimeiro on 21 August and found themselves almost cut off from retreat. However, at that moment, Wellesley was superseded by the arrival of Sir Harry Burrard and then the next day by Sir Hew Dalrymple. Both were cautious old men who had seen little recent fighting; rather than push the French, they were satisfied to open negotiations. Wellesley had sought to take control of the Torres Vedras area high ground and cut the French retreat with his unused reserve, but he was ordered to hold. Talks between Dalrymple and François Kellerman led to the signing of the Convention.

Dalrymple allowed terms for Portugal similar to those a garrison might receive for surrendering a fortress. The 20,900 French soldiers were evacuated from Portugal with all their equipment and 'personal property' (which was mostly looted Portuguese valuables) by the British Navy. They were transported to Rochefort, Junot arriving there on 11 October. Avoiding all Spanish entanglements and getting free transport meant the French travelled loaded, not light like a defeated garrison marching to their own lines.
