Then manning the frigate and two pinnaces, they set sail for the Cabezas, where they left the frigate, which was too large for the shallows over which they were to pass, and proceeded to Rio Francisco.  Here they landed, and, having ordered the pinnaces to return to the same place on the fourth day following, travelled through the woods towards Nombre de Dios, with such silence and regularity as surprised the French, who did not imagine the Symerons so discreet or obedient as they appeared, and were, therefore, in perpetual anxiety about the fidelity of their guides, and the probability of their return.  Nor did the Symerons treat them with that submission and regard which they paid to the English, whose bravery and conduct they had already tried.

At length, after a laborious march of more than seven leagues, they began to hear the hammers of the carpenters in the bay, it being the custom, in that hot season, to work in the night; and, in a short time, they perceived the approach of the recoes, or droves of mules, from Panama.  They now no longer doubted that their labours would be rewarded, and every man imagined himself secure from poverty and labour for the remaining part of his life.  They, therefore, when the mules came up, rushed out and seized them, with an alacrity proportioned to their expectations.  The three droves consisted of one hundred and nine mules, each of which carried three hundred pounds’ weight of silver.  It was to little purpose that the soldiers, ordered to guard the treasure, attempted resistance.  After a short combat, in which the French captain and one of the Symerons were wounded, it appeared with how much greater ardour men are animated by interest than fidelity.

As it was possible for them to carry away but a small part of this treasure, after having wearied themselves with hiding it in holes and shallow waters, they determined to return by the same way, and, without being pursued, entered the woods, where the French captain, being disabled by his wound, was obliged to stay, two of his company continuing with him.

When they had gone forward about two leagues, the Frenchmen missed another of their company, who, upon inquiry, was known to be intoxicated with wine, and supposed to have lost himself in the woods, by neglecting to observe the guides.

But common prudence not allowing them to hazard the whole company by too much solicitude for a single life, they travelled on towards Rio Francisco, at which they arrived, April the 3rd; but, looking out for their pinnaces, were surprised with the sight of seven Spanish shallops, and immediately concluded, that some intelligence of their motions had been carried to Nombre de Dios, and that these vessels had been fitted out to pursue them, which might, undoubtedly, have overpowered the pinnaces and their feeble crew.  Nor did their suspicion stop here; but immediately it occurred to them, that their men had been compelled, by torture, to discover where their frigate and ship were stationed, which, being weakly manned, and without the presence of the chief commander, would fall into their hands, almost without resistance, and all possibility of escaping be entirely cut off.
