"I understand, sir. Of course, the passes between Madrid and Avila might be retained for some little time, especially if the defenders had a few guns; but they would be liable to be taken in the rear by a force at Avila, where there were, when I went down south, over five thousand men. As to the troops coming from the north, they would doubtless march on Salamanca. From that town they would cross the Huebra and Yeltes so near their sources that no difficulty would be caused by the blowing up of bridges, if any exist; but the pass over the Sierra de Gatta, on the south of Ciudad, might be defended by a small force, without difficulty." The maps were now got out, and the matter gone into minutely. After an hour's conversation, Lord Fitzroy said: "Thank you, Colonel O'Connor. Some of the information that you have given me will assuredly be very useful, if we besiege Ciudad. From what we hear, there are a good many changes being made in the French command. Napoleon seems about to engage in a campaign with Russia, and is likely to draw off a certain portion of the forces here and, while these changes are being made, it would seem to offer a good opportunity for us to strike a blow." On the last day of December, Terence received the following order: "Colonel O'Connor will draw six days' rations from the commissariat and, at daybreak tomorrow, march to the river Aqueda and, on the following day, will ford that river and will post himself along the line of the Yeltes, from its junction with the Huebra to the mountains; and will prevent any person or parties crossing from this side. It is of the highest importance that no intelligence of the movements of the army should be sent, either by the garrison of Ciudad or by the peasantry, to Salamanca. When his provisions are exhausted, he is authorized to hire carts and send in to the army round Ciudad but, if possible, he should obtain supplies from the country near him, and is authorized to purchase provisions, and to send in accounts and vouchers, for such purchases, to the paymaster's department." "Hurrah, Ryan," he exclaimed on reading the order, "things are going to move, at last! This means, of course, that the army is going to besiege Ciudad at once; and that we are to prevent the French from getting any news of it, until it is too late for them to relieve it. For the last month, guns and ammunition have been arriving at Almeida; and I thought that this weary time of waiting was drawing to an end." "I am glad, indeed, Terence. I must say that I was afraid that we should not be moving until the spring. Shall we go in and say goodbye to our fellows?"
