In 1808 Sir Arthur Wellesley (later the Duke of Wellington) inflicted a major defeat on Napoleon's forces at the battle of Vimiero, but promptly signed an armistice and convention (negotiated by Sir Hew Dalrymple with General Junot). The Convention permitted the evacuation of the latter's defeated army from Portugal to Bayonne - along with its equipment and its plunder. This disgraceful Convention was regarded by the people of Britain - government ministers excepted - as a betrayal of Britain's allies, Portugal and Spain. Some of the troops repatriated under this agreement fought against Sir John Moore's expeditionary force the following year, forcing his evacuation from northern Spain. Wordsworth's enormous pamphlet on the betrayal of the Iberian patriots by Britain's officer class is one of the most remarkable political documents produced by a Romantic poet. Here the text of W J B Owen's 1968 edition is republished for the bicentennial, with a critical symposium by Richard Gravil, Simon Bainbridge, David Bromwich, Timothy Michael and Patrick Vincent.
