Donelson's flotilla, after being joined by a number of other boats, especially at the mouth of the Clinch, consisted of some thirty craft, all told—flat-boats, dug-outs, and canoes. There were probably two or three hundred people, perhaps many more, in the company; among them, as the journal records, "James Robertson's lady and children," the latter to the number of five. The chief boat, the flag-ship of the flotilla, was the Adventure, a great scow, in which there were over thirty men, besides the families of some of them.

They embarked at Holston, Long Island, on December 22d, but falling water and heavy frosts detained them two months, and the voyage did not really begin until they left Cloud Creek on February 27, 1780. The first ten days were uneventful. The Adventure spent an afternoon and night on a shoal, until the water fortunately rose, and, all the men getting out, the clumsy scow was floated off. Another boat was driven on the point of an island and sunk, her crew being nearly drowned; whereupon the rest of the flotilla put to shore, the sunken boat was raised and bailed out, and most of her cargo recovered. At one landing-place a man went out to hunt, and got lost, not being taken up again for three days, though "many guns were fired to fetch him in," and the four-pounder on the Adventure was discharged for the same purpose. A negro became "much frosted in his feet and legs, of which he died." Where the river was wide a strong wind and high sea forced the whole flotilla to lay to, for the sake of the smaller craft. This happened on March 7th, just before coming to the uppermost Chickamauga town; and that night, the wife of one Ephraim Peyton, who had himself gone with Robertson, overland, was delivered of a child. She was in a boat whose owner was named Jonathan Jennings.

The next morning they soon came to an Indian village on the south shore. The Indians made signs of friendliness, and two men started toward them in a canoe which the Adventure had in tow, while the flotilla drew up on the opposite side of the river. But a half-breed and some Indians jumping into a pirogue paddled out to meet the two messengers and advised them to return to their comrades, which they did. Several canoes then came off from the shore to the flotilla. The Indians who were in them seemed friendly and were pleased with the presents they received; but while these were being distributed the whites saw a number of other canoes putting off, loaded with armed warriors, painted black and red. The half-breed instantly told the Indians round about to paddle to the shore, and warned the whites to push off at once, at the same time giving them some instructions about the river. The armed Indians went down along the shore for some time as if to intercept them; but at last they were seemingly left behind.

In a short time another Indian village was reached, where the warriors tried in vain to lure the whites ashore; and as the boats were hugging the opposite bank, they were suddenly fired at by a party in ambush, and one man slain. Immediately afterwards a much more serious tragedy occurred. There was with the flotilla a boat containing twenty-eight men, women, and children, among whom small-pox had broken out. To guard against infection, it was agreed that it should keep well in the rear; being warned each night by the sound of a horn when it was time to go into camp. As this forlorn boat-load of unfortunates came along, far behind the others, the Indians, seeing its defenceless position, sallied out in their canoes, and butchered or captured all who were aboard. Their cries were distinctly heard by the rearmost of the other craft, who could not stem the current and come to their rescue. But a dreadful retribution fell on the Indians; for they were infected with the disease of their victims, and for some months virulent small-pox raged among many of the bands of Creeks and Cherokees. When stricken by the disease, the savages first went into the sweat-houses, and when heated to madness, plunged into the cool streams, and so perished in multitudes.

When the boats entered the Narrows they had lost sight of the Indians on shore, and thought they had left them behind. A man, who was in a canoe, had gone aboard one of the larger boats with his family, for the sake of safety while passing through the rough water. His canoe was towed alongside, and in the rapids it was overturned, and the cargo lost. The rest of the company, pitying his distress over the loss of all his worldly goods, landed, to see if they could not help him recover some of his property. Just as they got out on the shore to walk back, the Indians suddenly appeared almost over them, on the high cliffs opposite, and began to fire, causing a hurried retreat to the boats. For some distance the Indians lined the bluffs, firing from the heights into the boats below. Yet only four people were wounded, and they not dangerously. One of them was a girl named Nancy Gower. When, by the sudden onslaught of the Indians, the crew of the boat in which she was were thrown into dismay, she took the helm and steered, exposed to the fire of the savages. A ball went through the upper part of one of her thighs, but she neither flinched nor uttered any cry; and it was not known that she was wounded until, after the danger was past, her mother saw the blood soaking through her clothes. She recovered, married one of the frontiersmen, and lived for fifty years afterwards, long enough to see all the wilderness filled with flourishing and populous States.

One of the clumsy craft, however, did not share the good fortune that befell the rest, in escaping with so little loss and damage. Jonathan Jennings' boat, in which was Mrs. Peyton, with her new-born baby, struck on a rock at the upper end of the whirl, the swift current rendering it impossible for the others to go to his assistance; and they drifted by, leaving him to his fate. The Indians soon turned their whole attention to him, and from the bluffs opened a most galling fire upon the disabled boat. He returned it as well as he could, keeping them somewhat in check, for he was a most excellent marksman. At the same time he directed his two negroes, a man and woman, his nearly grown son, and a young man who was with him, to lighten the boat by throwing his goods into the river. Before this was done, the negro man, the son, and the other young man most basely jumped into the river, and swam ashore. It is satisfactory to record that at least two of the three dastards met the fate they deserved. The negro was killed in the water, and the other two captured, one of them being afterwards burned at the stake, while the other, it is said, was ultimately released. Meanwhile Mrs. Jennings, assisted by the negro woman and Mrs. Peyton, actually succeeded in shoving the lightened boat off the rock, though their clothes were cut in many places by the bullets; and they rapidly drifted out of danger. The poor little baby was killed in the hurry and confusion; but its mother, not eighteen hours from child-bed, in spite of the cold, wet, and exertion, kept in good health. Sailing by night as well as day, they caught up with the rest of the flotilla before dawn on the second morning afterwards, the men being roused from their watch-fires by the cries of "help poor Jennings," as the wretched and worn-out survivors in the disabled boat caught the first glimpse of the lights on shore.

Having successfully run the gauntlet of the Chickamauga banditti, the flotilla was not again molested by the Indians, save once when the boats that drifted near shore were fired on by a roving war party, and five men wounded. They ran over the great Muscle Shoals in about three hours without accident, though the boats scraped on the bottom here and there. The swift, broken water surged into high waves, and roared through the piles of driftwood that covered the points of the small islands, round which the currents ran in every direction; and those among the men who were unused to river-work were much relieved when they found themselves in safety. One night, after the fires had been kindled, the tired travellers were alarmed by the barking of the dogs. Fearing that Indians were near by, they hastily got into the boats and crossed to camp on the opposite shore. In the morning two of them returned to pick up some things that had been left; they found that the alarm had been false, for the utensils that had been overlooked in the confusion were undisturbed, and a negro who had been left behind in the hurry was still sleeping quietly by the camp-fires.

On the 20th of the month they reached the Ohio. Some of the boats then left for Natchez, and others for the Illinois country; while the remainder turned their prows up stream, to stem the rapid current—a task for which they were but ill-suited. The work was very hard, the provisions were nearly gone, and the crews were almost worn out by hunger and fatigue. On the 24th they entered the mouth of the Cumberland. The Adventure, the heaviest of all the craft, got much help from a small square-sail that was set in the bow.

Two days afterwards the hungry party killed some buffalo, and feasted on the lean meat, and the next day they shot a swan "which was very delicious," as Donelson recorded. Their meal was exhausted and they could make no more bread; but buffalo were plenty, and they hunted them steadily for their meat; and they also made what some of them called "Shawnee salad" from a kind of green herb that grew in the bottoms.

On the last day of the month they met Col. Richard Henderson, who had just come out and was running the line between Virginia and North Carolina. The crews were so exhausted that the progress of the boats became very slow, and it was not until April 24th that they reached the Big Salt Lick, and found Robertson awaiting them. The long, toilsome, and perilous voyage had been brought to a safe end.
