There was only one thing to be done—to cross these woods, rocks, and mountains, however inaccessible they seemed, and surprise our enemies, taking advantage of the place by coming upon them from above, where they certainly would not expect us. As to our prisoners, horses, and baggage, since through all our march a troop of three hundred Spaniards had been dogging our steps without daring to approach, we would leave eighty men to guard them—enough to beat four times as many Spaniards.

At nightfall we set out, leaving our eighty men, with orders to the sentinels to fire and beat the retreat and the diane at the usual times, to make the three hundred Spaniards who lurked near us think that we had not left the camp. If we were successful we would send back messengers with the good news, but if, an hour after the firing ended, none of us returned, they were to escape how they could.

All being arranged, we prayed in a low voice, not to be heard by the Spaniards, and set out by the moonlight, two hundred men of us, through this country of rocks, woods, and frightful precipices, where we went leaping and climbing, our feet seeming to be much less use to us than our hands and knees.

On the 14th, at the break of day, when we had already gained a great height, and were climbing on in profound silence, with the Spanish intrenchments to our left, we saw a sentry party, which, thanks to the fog—always thick in this country till ten o'clock in the morning—did not discover us. When it had passed we went straight to the place where we had seen it, and we found that there was really a road there. This, when we had halted half an hour to take breath, we followed, guided by the voices of the Spaniards, who were at matins. But we had only gone a few steps when we found two sentinels, very far advanced, on whom we were forced to fire, which warned the Spaniards, who dreamed of nothing less than our coming upon them from above, since they only expected us from below. So those who guarded the intrenchment—about five hundred men—being taken at a disadvantage when they thought they had all the advantage on their side, were so terribly frightened that, when we fell upon them all at once, they vanished from the place in an instant, and escaped into the thick fog.

This unexpected assault so utterly upset their plans that the men in the second intrenchment all passed into the lowest one, where they prepared to defend themselves. We fought them a whole hour, under cover of the first intrenchment, which we had taken, and which commanded them, being higher up the mountain side. But as they would not yield we fancied our shots must have missed, since the fog hindered us from seeing our foes distinctly, so, resolved to waste no more powder, we went down, and fell right on the spot whence they had been firing. Then we assailed them furiously, and at sight of our weapons close upon them—which hitherto the fog had concealed—they left everything, and fled into the road below the intrenchments. Here they fell into their own trap; for, thinking it was the only road we could possibly come by, they had cut down trees and blocked it up, and their way being stopped, we could fire upon them from their intrenchment without once missing aim.

At last, seeing the river in the ravine running down with blood, and tired of pursuing the fugitives, we spared the few remaining Spaniards. After we had chanted the 'Te Deum,' sixty of us went to tell those left in the camp of the victory which Heaven had vouchsafed to us. We found them on the point of giving battle to the three hundred Spaniards, who had already (on finding out their weakness) sent a message to them by an officer to tell them that it was hopeless for them to expect to cross the valley, and to offer terms of peace. To which our men replied that were there as many Spaniards as the blades of grass in the prairie they would not be afraid, but would pass through in spite of them, and go where they liked!

The officer, being just dismissed with this message when we arrived, shrugged his shoulders with astonishment when he saw us safe back again, and mounted on the horses of his comrades of the intrenchments. He rode off with the news to his troop, whom we presently fired upon, to rid them altogether from their desire to follow in our wake. Unfortunately for them they had not time to mount their horses, so after a brief conflict, in which a great number of them fell, we let the rest go, though we kept their horses. Then, with our baggage, we joined those of our men who had stayed to guard the intrenchments. In both these combats we had only two men slain and four wounded.

Continuing our journey, we passed one more Spanish intrenchment, where, since the news of our victory had gone before us, we found no resistance. At last, on the sixteenth day of our march, we reached the river which we had been seeking eagerly, by whose means we meant to gain the sea into which it flowed.

At once we entered the woods which are on its banks, and everyone set to work in good earnest to cut down trees, in order to construct piperies, with which to descend the river. The reader may perhaps imagine that these piperies were some kind of comfortable boat to carry us pleasantly along the stream, but they were anything but this. We joined together four or five trunks of a kind of tree with light floating wood, merely stripping off their bark, and binding them, instead of cord, with a climbing plant growing in those forests, and embracing the trees like ivy, and when these structures, each large enough to hold two men (and in appearance something like huge wicker baskets) were completed, vessels and crew were ready.
