Wellington's position was, however, a very difficult one, and his responsibilities were immense. Allowing for the detachments which were massing to check three other French columns advancing in different directions, he had but 25,000 men with which to attempt to raise the siege of Ciudad Rodrigo, or to draw off the besieged garrison. Massena had under him 60,000 French veterans, and was desiring nothing more than that Wellington should attack him. The chances of victory then were by no means strong, and in any case victory could only have been purchased by a loss of men which would have completely crippled the British general, and would have rendered it absolutely necessary for him to fall back again at once. A defeat or even a heavy loss of men, would have so dispirited the faint-hearted Government at home that they would undoubtedly have recalled the whole expedition, and resigned Portugal to its fate. Thus Wellington decided not to risk the whole fate of the British army and of Portugal for merely a temporary advantage, and so stood firm against the murmurs of his own troops, the furious reproaches of the Portuguese and Spaniards, and the moving entreaties for aid of the gallant governor of the besieged town. At the same time that he refused to risk a general battle, he kept Craufurd's division in advance of the Coa, and within two hours' march of the enemy, thereby encouraging the garrison of Ciudad Rodrigo, and preventing Massena from pushing forward a portion of his army while the rest pursued the siege. Craufurd's front was guarded by the Agueda, a river only passable by two or three bridges and fords in wet weather, but fordable in many places in the dry season. At the commencement of June the Agueda fell, and the French crossed in strength at various places. Craufurd, however, still maintained his position in front of the Coa with great skill and boldness. He had under his command only 4000 infantry, 1100 cavalry, and six guns, and his maintenance of his position, almost within gun-shot of an enemy's army, 60,000 strong, for three months, is one of the finest feats of military audacity and ability ever performed. Until the 11th of July the boys remained quietly at a cottage occupied by peasants, who believed their story that they were only waiting to proceed when the French army advanced. They were freed from molestation or inquiry upon the part of the French by the pass with which Madame Reynier had supplied them. Upon that day Ciudad Rodrigo surrendered, and Massena prepared at once to enter Portugal. Upon the 21st the cavalry advanced in great force, and upon the following day the boys resolved upon endeavoring to rejoin the British army. The Agueda was now easily fordable in many places, but the boys determined to swim across, at a distance from the point at which the French army was now pouring forward.
