While the negotiations were going on, Dupont sent secret orders to Vedel to abscond during the night, and to retreat on Madrid as fast as he was able. Chabert and Marescot had of course no knowledge of this, or they would hardly have consented to include that general’s troops in the convention. In accordance with his superior’s orders, and with the obvious necessities of the case, Vedel made off on the night of July 20-21, leaving only a screen of pickets in front of his position, to conceal his departure from the Spaniards as long as was possible. On the return of his plenipotentiaries to his camp on the morning of the twenty-first, Dupont learnt, to his surprise and discontent, that they had included Vedel’s division in their bargain with Castaños. But as that officer was now far away--he had reached La Carolina at daybreak and Santa Elena by noon--the commander-in-chief hoped that his troops were saved. The anger of the Spaniards at discovering the evasion of the second French division may easily be imagined. Reding, who was the first to become aware of it, sent down an officer into Dupont’s camp, with the message that if Vedel did not instantly return, he should regard the convention as broken, and fall upon the surrounded troops: he should give no quarter, as he considered that treachery had been shown, and that the armistice had been abused. Dupont could not hope to make a stand, and was at the enemy’s mercy. He directed his chief of the staff to write an order bidding Vedel to halt, and sent it to him by one of his aides-de-camp, accompanied by a Spanish officer. This did not satisfy Reding, who insisted that Dupont should write an autograph letter of his own in stronger terms. His demand could not be refused, and the two dispatches reached Vedel almost at the same hour, as he was resting his troops at Santa Elena before plunging into the passes. Vedel, as all his previous conduct had shown, was weak and wanting in initiative. Some of his officers tried to persuade him to push on, and to leave Dupont to make the best terms for himself that he could. Much was to be said in favour of this resolve: he might have argued that since he had never been without the power of retreating, it was wrong of his superior to include him in the capitulation. His duty to the Emperor would be to save his men, whatever might be the consequences to Dupont. The latter, surrounded as he was, could hardly be considered a free agent, and his orders might be disregarded. But such views were far from Vedel’s mind: he automatically obeyed his chief’s dispatch and halted. Next day he marched his troops back to Baylen, in consequence of a third communication from Dupont.
