Convention of Cintra

• 1. Introduction

  ›

  The Convention of Cintra began on the 30th of August 1808, in the Palace of Queluz, with a signature that left Britain furious. Nine days earlier, French forces under Jean-Andoche Junot had been defeated on the battlefield at Vimeiro. The British held every advantage. Yet by the end of August, those same defeated French troops were being loaded onto Royal Navy ships, sailing for France with their weapons, their baggage, and everything they owned. How did a clear British victory turn into what many in the United Kingdom called a national disgrace? The answer lies in three British commanders, a cautious instinct, and a set of negotiations that outran the battle itself.

  Sir Arthur Wellesley won at Vimeiro on the 21st of August 1808, routing Junot's forces and leaving the French almost cut off from any path of retreat. Wellesley saw the opening clearly. He wanted to seize the high ground around Torres Vedras, deploy his unused reserve, and block the French withdrawal entirely. The order came back: hold.

  The order came from Sir Harry Burrard, who had arrived to supersede Wellesley in command that same day. The following day brought another change, when Sir Hew Dalrymple arrived to take supreme command. Both men had seen little recent fighting. Rather than pursue a broken enemy, they opened talks.

• 3. The Terms and Their Cost

  ›

  François Kellerman negotiated on the French side, and Dalrymple agreed to terms that critics found extraordinary. Some 20,900 French troops were evacuated from Portugal to Rochefort, a port on France's Atlantic coast, aboard Royal Navy vessels. They took all their equipment and personal property with them. Junot himself reached Rochefort on the 11th of October.

  Dalrymple granted the French conditions comparable to what a garrison might receive when surrendering a fortress under honourable terms. The practical effect was striking: rather than marching home lightly as a defeated force, the French army travelled fully loaded. Britain had used its own navy to return an intact enemy force to France.

• 4. Scandal and Inquiry

  ›

  Back in Britain, outrage followed almost immediately. Critics argued that a chance to destroy Junot's army entirely had been thrown away. There was also a separate embarrassment: a Russian naval squadron, blockaded in Lisbon, had been allowed to sail to Portsmouth and eventually return to Russia, even though Britain and Russia were then at war. Dalrymple had not consulted the Royal Navy about this complication before signing.

  Wellesley, Burrard, and Dalrymple were all recalled from Portugal. An official inquiry convened in the Great Hall at the Royal Hospital Chelsea, running from the 14th of November to the 27th of December 1808. Dalrymple's reports had been written to direct scrutiny toward Wellesley, who still held a ministerial post in the British government. Wellesley defended himself on a precise legal point: Junot's surrender terms were, technically, lawful. All three men were cleared.

  The practical outcomes were not equal. Wellesley returned to active duty in Portugal before long. Burrard and Dalrymple were quietly moved into retirement and never served again. Sir John Moore, reflecting on the inquiry, put the popular view plainly: "Sir Hew Dalrymple was confused and incapable beyond any man I ever saw head an army. The whole of his conduct then and since has proved him to be a very foolish man."

• 5. Poets Against a Peace

  ›

  Lord Byron lamented the convention in his Childe Harold's Pilgrimage, giving the agreement a place in literary history alongside its military one. William Wordsworth, who would later become Britain's Poet Laureate, responded with an extended prose pamphlet titled The Convention of Cintra, published in 1808. He also wrote a sonnet composed while drafting the pamphlet, which mourns the bondage felt by "suffering Spain", even though the convention itself concerned only Portugal.

  The sonnet was gathered into his collection Sonnets Dedicated to Liberty. Delays in getting the pamphlet into print meant that its more pointed journalistic and satirical passages were largely overlooked at the time, a fact that shaped how later readers understood Wordsworth's response to the war.
