a-a. Little forts built by Genl Wayne to exercise the garrison.

b. At 30 feet lower than the summit there are two Coal-mines horizontally, to the distance of forty to fifti feet.

Fort Lafayette contains two Barracks, three hexagonal towers in a wood, having artillery a powder magazine. the inclosure is composed of large pointed stakes closed together 15 or 16 feet high, the fort is square, of weak defence, and even as a nothing against cannon.

Note, the Islots marked in black, denote that they are almost intirely built, the other streets in the islots [small islands; pron. eye-lut] are untilled, and are built, but in places, where there are little black square spots.

The rivers augment or diminish, according to the rains, or Drought, the Monogahela near the town, and at the opposite shore, is commonly 10 or 12 feet, in the middle 4, 5, or 6, the Allegany is 20, 25, or 26 feet.

Collot’s Fort Fayette

Georges Henri Victor Collot (1750–1805) was a French military officer sent to gather intelligence on the American and Spanish territories. His trip down the Ohio and Mississippi in 1796 aroused suspicion, and he was arrested separately by both the American Zebulon Pike and the Spanish Governor, Francisco Luis Héctor de Carondelet. Collot’s maps, illustrations, and written descriptions contained a wealth of information, but they were not published until 1826.

Of Fort Fayette, Collot’s opinion appears, at the least, unfavorable:

The reasons which determined Major Craig, who was the planner of this work, to build it in this spot were, that the Indians of the Six Nations, with whom the Americans were then at war, occupied a part of the Allegany river, which is situated on the right of the town, and that it was therefore necessary to place the fort on the right, and as near as possible to the town, which was punctually executed. He did not reflect, that if, by chance, the Indians should contrive to land two miles above the fort, on the left of the Allegany, and take possession of the heights, by which manoeuvre they could reach the foot of the town without being seen, they might kill the inhabitants, and burn the place, before any intelligence could reach the spot, or a cannon or musket be fired.

Fort La Fayette is merely a square with four bastions, on the platforms of which are erected-block houses or barracks. In each of these block-houses is an embrasure on the side next the country, on which are placed pieces of cannon; on that which looks towards the town a small powder magazine is built, covered only with planks. Palisades from ten to eleven feet, placed on a kind of parapet, which is only three feet in height, including the depth of the ditch already half filled up, surround this fort, and give it the form of a bullock-pen. ln a dark night four grenadiers, with a dozen faggots of dry wood, might burn the fort and all the garrison, and not a single individual escape.^[2]Victor Collot, A Journey in North America, 40–41.

There is little doubt that by the time Lewis arrived in the summer of 1803, fortifications and security at Fort Fayette had improved significantly. Originally meant to be named for the famous Revolutionary War hero, the Marquis de Lafayette, Fort Fayette was built in 1792 as a response to St. Clair’s defeat—one of the worst defeats in U.S. Army in history. The garrison protected Pittsburgh from Indian attacks, supplied the western posts with ammunition, and for a time served as the headquarters of the U.S. Army.^[3]Mrs. Elvert M.
