Upon the other hand, the position of the British, even after winning a victory, was by no means a satisfactory one; they had already learnt that it was useless to rely in the slightest degree upon Portuguese promises or Portuguese assistance, and that, even in the matter of provisions and carriage, their commander-in-chief expected to be maintained by those who had come to aid in freeing the country of the French, instead of these receiving any help from him. In carriage the British army was wholly deficient; of cavalry they had none. When Sir John Moore landed there would be but four days' provisions on-shore for the army, and were the fleet driven off by a gale, starvation would at once threaten them.
The gallantry with which the French had fought in both engagements, the skill with which they had been handled, and above all, the quickness and steadiness with which, after defeat, they had closed up their ranks and drawn off in excellent order, showed that the task of expelling such troops from the country would, even if all went well in other respects, be a very formidable one, and the offer of a conference was therefore at once embraced by Sir Hew Dalrymple.
Kellermann was admitted to the camp. His mission was to demand a cessation of arms in order that Junot might, under certain conditions, evacuate Portugal. The advantage of freeing the country from the French without further fighting was so evident that Sir Hew at once agreed to discuss the terms, and took Sir Arthur Wellesley into his counsels. The latter quite agreed with the policy by which a strong French army would be quietly got out of the country, in which it held all the military posts and strong positions. A great moral effect would be produced, and the whole resources of Portugal would then be available for operations in Spain.
By the afternoon the main points of the convention had been generally agreed upon. The French were to evacuate Portugal, and were to be conveyed in the English vessels to France with their property, public or private. There was to be no persecution of persons who had been the adherents of France during the occupation; the only serious difference that arose was as to the Russian fleet in the Tagus. Kellermann proposed to have it guaranteed from capture, with leave to return to the Baltic. This, however, was refused, and the question was referred to Admiral Cotton, who, as chief representative of England, would have to approve of the treaty before it could be signed.
