The famous "_Convention of Cintra_" (most absurdly so named, as it was in fact concluded thirty miles from Cintra) was signed accordingly on the 30th of August; and the French army wholly evacuated Portugal in the manner provided for.

The English people heard with indignation that the spoilers of Portugal had been suffered to escape on such terms; and the article concerning private property gave especial offence, as under that cover the French removed with them a large share of the plunder which they had amassed by merciless violence and rapacity during their occupation of the Portuguese territories.

A parliamentary investigation was followed by a court-martial, which acquitted Dalrymple.

In truth it seems now to be admitted, by competent judges, that after Burrard had interfered so as to prevent Wellesley from instantly following up the success of Vimiero, and so enabled Junot to re-occupy Lisbon and secure the pass of the Torres Vedras, it would have been imprudent to decline the terms proffered by a repelled, but still powerful enemy--who, if driven to extremities, could hardly fail to prolong the war, until Napoleon should be able to send him additional forces from Spain.
Meanwhile Portugal was free from the presence of her enemies; England had obtained a permanent footing within the Peninsula; what was of still higher moment, the character of the British army was raised not only abroad, but at home; and had the two insurgent nations availed themselves, as they ought to have done, of the resources which their great ally placed at their command, and conducted their own affairs with unity and strength of purpose, the deliverance of the whole peninsula might have been achieved years before that consummation actually took place.
The Portuguese, however, split into factions--under leaders whose primary objects were selfish, who rivalled each other in their absurd jealousy of England, afforded to her troops no such supplies and facilities as they had the best title to demand and expect, and wasted their time in petty political intrigues, instead of devoting every energy to the organisation of an efficient army, and improving the defences of their naturally strong frontier.

The Spaniards conducted themselves with even more signal imprudence.
