At length, on the 18th of January, 1671, the march on Panama actually began, with a force of thirteen hundred picked men, five hundred being left to garrison the fort and one hundred and fifty to seize some Spanish vessels that were in the river. The means of conveyance being limited, and the need of marching light important, a very small supply of provisions was taken, it being expected to find an abundance on the route. But in this the raiders were seriously at fault, the Spaniards fleeing with all their cattle and cutting all the growing grain, so that the buccaneers soon found themselves almost destitute of supplies. The journey was made in boats up the river as far as practicable, five small vessels carrying the artillery. At the end of the second day most of the men were forced to abandon the boats and prosecute their journey on foot. On the third day they found themselves in a marshy forest, which they traversed with difficulty and reached the town of Cedro Bueno. Here they had hoped to find food, but the place was deserted and not a scrap of provisions left. The affair was now growing very serious, all their food having been consumed and they left in imminent danger of starvation. Many of them were reduced to eat the leaves of the trees in their extremity. They found themselves also benumbed with cold as they spent the night unsheltered on the chilly river-bank. During the next day their route followed the stream, the canoes being dragged along, or rowed where the water was of sufficient depth. The Spaniards still carried away all food from the country before them, the only things they found being some large sacks of hides. These, in their extremity, were used as food, the leather being scraped, beaten, and soaked in water, after which it was roasted. Even then it could not be swallowed without the aid of copious draughts of water. Only the courage and determination of the chiefs induced the men to go on under such severe privations. The fifth day’s journey ended as badly as the previous ones, the only food found being a little flour, fruit, and wine, so small in quantity that Morgan had it distributed among the weaker members of his troop, some of whom were so faint as to seem on the point of death. For the rest of the men there was nothing to eat but leaves and the grass of the meadows. The feebler men were now put on board the boats, the stronger continuing to travel by land, but very slowly, frequent rests being needed on account of their great exhaustion. It seemed, indeed, as if the expedition would have to be abandoned, when, to their delirious joy, they found a great supply of maize, which the Spaniards by some oversight had abandoned in a granary. Many of them, in their starving condition, devoured this grain raw. Others roasted it wrapped in banana leaves. The supply was soon exhausted, but for a time it gave new vigor to the famished men.
