These circumstances created a necessity for the utmost caution as well as expedition in their movements, and they accordingly hastily embarked on the Ohio with only seven boatmen. They were hotly pursued the whole way by Indians, but succeeded in keeping in advance until they arrived at the mouth of Limestone Creek, at the spot where the city of Maysville now stands. They ascended this creek a short distance with their boat, and concealed their cargo at different places in the woods along its banks. They then turned their boat adrift, and directed their course to Harrodstown, intending to return with a sufficient escort to insure the safe transportation of the powder to its destination. This in a short time was successfully effected, and the colonists were thus abundantly supplied with the means of defense against the fierce enemies who beset them on all sides.[33] It was fortunate for Virginia, says a recent writer,[34] that she had at this time, on her western borders, an individual of rare military genius, in the person of Colonel George Rogers Clarke, "_the Hannibal of the West_," who not only saved her back settlements from Indian fury, but planted her standard far beyond the Ohio. The Governor of the Canadian settlements in the Illinois country, by every possible method, instigated the Indians to annoy the frontier. Virginia placed a small force of about 250 men under Clark, who, descending the Ohio, hid their boats, and marched northwardly, with their provisions on their backs. These being consumed, they subsisted for two days on roots, and, in a state of famine, appeared before Kaskaskias, unseen and unheard. At midnight they surprised and took the town and fort, which had resisted a much larger force; then seizing the golden moment, sent a detachment who with equal success surprised three other towns. Rocheblave, the obnoxious Governor, was sent to Virginia. On his person were found written instructions from Quebec to excite the Indians to hostilities, and reward them for the scalps of the Americans. The settlers transferred their allegiance to Virginia, and she, as the territory belonged to her by conquest and charter, in the autumnal session of 1778 erected it into a county to be called Illinois. Insulated in the heart of the Indian country, in the midst of the most ferocious tribes, few men but Clark could have preserved this acquisition. Hamilton, the Governor of Detroit, a bold and tyrannical personage, determined, with an overwhelming force of British and Indians, to penetrate up the Ohio to Fort Pitt to sweep all the principal settlements in his way, and besiege Kaskaskias. Clark despaired of keeping possession of the country, but he resolved to preserve this post, or die in its defense. While he was strengthening the fortifications, he received information that Hamilton, who was at Fort St. Vincent (Vincennes,) had weakened his force by sending some Indians against the frontiers.
