Terence now produced a map with which he had been supplied, and a considerable time was spent in obtaining full particulars of the country through which the troops might have to march; ascertaining the best spots for resistance when retreating, or for attacking columns who might be despatched in pursuit of them; and in discussing the manner and direction in which their operations would most alarm and annoy the enemy.

It was finally agreed that Terence should break up his battalions into three parties. Two of these consisted each of half a battalion, 500 strong, and would be under the command of Bull and Macwitty. Each of them would be accompanied by 300 guerillas, who would act as scouts and, in case opportunity should offer, join in any fighting that might take place.

The other two half battalions formed the third body, under the command of Terence, himself; and would, with the main force of the guerillas, occupy the roads between Zamora, Salamanca, and Valladolid. In this way the French would be harassed at several points, and would find it so difficult to obtain information as to the real strength of the foe that was threatening them, that they would be obliged to send up a considerable force to oppose them; and would hesitate to undertake any serious advance into Portugal until the question was cleared up, and their lines of communication assured again.

It was agreed, in the first place, that the forces should unite in the mountains west of Braganza, between the river Esla on the east and Tera on the north; affording a strong position from which, in case of any very large force mustering against them, they could retire across the frontier into Portugal. Terence had been supplied with money, and an authority to give orders on the paymaster's department for such purchases as were absolutely necessary. Moras was also well supplied, having not only the money that had been sent him, but the proceeds of a successful attack upon a convoy proceeding to Salamanca; in which he had captured a commissariat chest, with a considerable sum of money, besides a large number of cattle and several waggon loads of flour. All these provisions, with some that Terence had authority to draw from the stores at Miranda, were to be taken to the spot they had chosen as their headquarters in the hills.

"You beat me altogether, Terence," Ryan said as, after all these matters had been arranged, they rode out from the guerilla's camp. "It is only about three months since I saw you. Then you could only just get along in Spanish. Now you are chattering away in it as if you had never spoken anything else, all your life."

"Well, you see, Dick, I knew just enough, when I was taken prisoner, to be able to, as you say, get along in it; and that made all the difference to me. If I had known nothing at all of it, I should not have been able to benefit by my trip with the muleteers in Spain. As it was, I was able to talk with them and, as we rode side by side all day; and sat together by a fire for hours, after we had halted when the day's journey was over, we did a tremendous lot of talking; and as you see, I came out, at the end of the month, able to get along really fluently. I, no doubt, make a good many mistakes, and mix a good many Portuguese words with my Spanish; but that does not matter in the least, so long as one is with friends; although it would matter a good deal if I were trying to pass as a Spaniard, among people who might betray me if they found out that I was English.

"I see that you have improved in Portuguese almost as much as I have in Spanish. It is really only the first drudgery that is difficult, in learning a language. When once one makes a start one gets on very fast; especially if one is not afraid of making mistakes. I never care a rap whether I make blunders or not, so that I can but make myself understood."

Three days later the two bodies were assembled in a valley, about equally distant from Miranda and Braganza. It had the advantage of being entered, from the east, only through a narrow gorge, which could be defended against a very superior force; while there were two mountain tracks leading from it, by which the force there could be withdrawn, should the entrance be forced. A day was spent by the leaders in making their final arrangements; while the men worked at the erection of a great wall of rocks, twelve feet high and as many thick, across the mouth of the gorge; collecting quantities of stones and rocks, on the heights on either side, to roll down upon any enemy who might endeavour to scale them; while another very strong party built a wall, six feet high, in a great semicircle round the upper mouth of the gorge, so that a column forcing its way through, thus far, would be met by so heavy a fire that they could only debouch into the valley with immense loss.

Two hundred men of the Minho regiment, drawn from Terence's party, were to occupy the valley; with three hundred of the guerillas, who would be able to do good service by occupying the heights, while the regular infantry held the newly-erected walls. One of Moras' most trusted lieutenants was to command them while, after some discussion, it was arranged that Herrara should be in general command of the garrison.

The brave fellow was reluctant to remain inactive; but he had been, for some time, seriously unwell, having been laid up for a time with a severe attack of dysentery; and was really unfit for any continued exertion, although he had made light of his illness, and refused to go on the sick list. Terence pointed out to him that the command was a very important one. Here all the plunder that they might obtain from the enemy would be carried; and if, by means of spies or traitors, the French obtained news of the situation of the post, he might be attacked in great force before the other detachments could arrive to his assistance.
