On the ensuing day, which was the tenth of their march, January 27, 1671, the pirates advanced at a very early hour, with their military music, and took the road leading to Panama. By the advice, however, of one of their guides, they quitted the main road and went out of the way across a thick wood through which there was no footpath. For this the Spaniards were unprepared, having confined themselves to the erection of batteries and construction of redoubts on the highway. They soon perceived the inutility of this measure and were obliged to relinquish their guns in order to oppose their enemies on the contrary side; but not being able to take their cannons away from their batteries, they were, consequently, incapacitated from making use of one part of their defensive means. After two hours' march the freebooters discovered the hostile army, which was a very fine one, well equipped, and was advancing in battle array. The soldiers were clad in party-colored silk stuffs, and the horsemen were seated upon their mettlesome steeds as if they were going to a bull-fight. The President in person took the command of this body of troops, which was of considerable importance, both for the country and likewise for the forces supported there by Spain. He marched against the pirates with four regiments of the line consisting of infantry, besides twenty-four hundred foot-soldiers of another description, four hundred horsemen, and twenty-four hundred wild bulls under the conduct of several hundred Indians and negroes. This army, which extended over the whole plain, was discovered by the pirates from the summit of a small eminence, and presented to them a most imposing appearance, insomuch that they were struck with a kind of terror. They now began to feel some anxiety as to the event of an engagement with forces so greatly superior to them in point of numbers, but they were soon convinced that they must actually conquer or die, and encouraged each other to fight till the very last drop of their blood was shed; a determination this, which, on the part of these intrepid men, was by no means a vain resolution. They divided themselves into three bodies, placed two hundred of their best marksmen in the front, and marched boldly against the Spaniards, who were drawn up in order of battle on a very spacious plain. The Governor immediately ordered the cavalry to charge the enemy, and the wild bulls to be at the same time let loose upon them. But the ground was unfavorable for this purpose; the horsemen encountered nothing but marshes, behind which were posted the two hundred marksmen, who kept up such a continual and well-directed fire that horses and men fell in heaps beneath their shots before it was possible to effect a retreat. Fifty horsemen only escaped this formidable discharge of musketry.
