Their greatest enemy was cold. It was now the end of October, and several times snow had fallen, and it was necessary to keep up large fires. This was a double inconvenience. In the first place, the smoke by day and the flames by night might betray the position of their camp; and in the second place, their tracks in the snow, which would speedily cover the hills, would enable the enemy to follow them wherever they moved. It was therefore determined that they could no longer maintain their position there, but must return to the plains.
Frequent communication had been kept up with Herrara, who reported that Salamanca was now occupied by so large a force that he was no longer able to maintain his position; and that he had fallen back across the Douro, and had established himself in the stronghold, from which he made frequent excursions towards Zamora and Benavente.
To Dick Ryan, in his prison, the first fortnight had passed slowly. That Terence would, as soon as he learned of his capture, make every effort to free him he knew well; but he could not see how he could give him any material aid. The French force at Salamanca was far too strong to admit of a possibility of any attempt to rescue him by force, and the barred windows and the sentry seemed to close every chance of communication from without. On the tenth day of his imprisonment, he noticed that the sergeant who brought his food had been changed.
"What has become of Sergeant Pipon?" he asked the non-commissioned officer who filled his place.
"He was killed yesterday evening, in the streets," the man replied. "It was not an ordinary broil, for he had half-a-dozen dagger stabs. It is some time since those dogs of Spaniards have killed a French soldier in the town, and there is a great fuss over it. The municipality will have to pay 10,000 dollars, if they cannot produce his murderer. It is curious, too, for Pipon was not a man to get drunk. He did not speak a word of the language, and therefore could not have had a dispute with a Spaniard.
"We have been ordered to be more vigilant than before. I suppose the authorities think that perhaps there was some attempt to bribe him and, on his seizing the man who made it, some of the fellow's comrades rushed upon him, and killed him."
Ryan wondered whether the supposition was a correct one, and whether the men concerned had been set at work by Terence, in order to effect his release. Two days later, on cutting the loaf that formed his day's ration of bread, he found a small piece of paper in its centre. It had evidently been put there before the bread was baked for, although he examined it very closely, he could find no sign in the crust of an incision by which the note might have been inserted. It contained only the words:
"Keep your eyes open, and be in readiness. Friends are working for your release."
So Terence was at work. Evidently the baker had been gained over, but how it had been contrived that this special loaf should have been handed to him he could not imagine; unless one of the men in charge of the distribution of the prison rations had been bribed. That something of the sort must have taken place he was certain and, although he was still unable to imagine how he could be got out of the prison, he felt that, in some way or another, Terence would manage it. He thought over the means by which the latter had escaped from the convent, but the laxity that had there prevailed, in allowing
people to come in to sell their goods to the prisoners, was not permitted in the prison where he was confined. The prisoners were, indeed, allowed to take exercise for an hour in the courtyard, but no civilian ever entered it, and twelve French soldiers watched every movement of those in the yard, and did not permit a single word to be exchanged.
Another week passed, and Ryan began to fear that his friends outside had abandoned the scheme as impossible, when one day he received another message:
"Do not undress tonight. On reaching the courtyard, take the first passage to the right. Follow it to the end. The bars of the window there have been nearly sawn through. Inclosed with this is a saw. Finish the work on the middle bars. You will find a cord hanging down outside. Friends will be awaiting you."
With the note was a very fine steel saw, coiled round and round, and a tiny phial of oil. Ryan gave a cry of delight as he read it; and then hid the saw and the oil bottle in his bed, made up the tiny note into a pellet, and swallowed it. As he ate his dinner, he pondered over how so much could have been managed. The courtyard of the prison was, he knew, some ten feet higher than the ground outside. Some one must, after nightfall, have climbed up to the passage window and sawn the bars almost asunder, with a saw as fine as the one he had received. The cuts could hardly have been perceptible, and had probably been filled in with dust or black lead, each night, after the work was done. The difficulty must have been great, for he had learned that sentries patrolled the street outside the prison, and the work could only have been carried on for two or three minutes at a time. How he was to get down to the courtyard he knew not, but probably a sentry had been found more amenable to a bribe than the old sergeant had been.
