No sooner were his wounds healed, than we find him in the fore front of the expedition against the Indians.  In 1779, he served as a captain in Bowman’s campaign.  He signalized his bravery in the unfortunate battle that ensued, and was with difficulty compelled to retire, when retreat became necessary.  The next year a party travelling from Harrodsburgh towards Logan’s fort, were fired upon by the Indians, and two of them mortally wounded One, however, survived to reach the fort, and give an account of the fate of his wounded companion.  Logan immediately raised a small party of young men, and repaired to the aid of the wounded man, who had crawled out of sight of the Indians behind a clump of bushes.  He was still alive.  Logan took him on his shoulders, occasionally relieved in sustaining the burden by his younger associates, and in this way conveyed him to the fort.  On their return from Harrodsburgh, Logan’s party were fired upon, and one of the party wounded.  The assailants were repelled with loss; and it was Logan’s fortune again to be the bearer of the wounded man upon his shoulders for a long distance, exposed, the while, to the fire of the Indians.

His reputation for bravery and hospitality, and the influence of a long train of connections, caused him to be the instrument of bringing out many immigrants to Kentucky.  They were of a character to prove an acquisition to the country.  Like his friends, Daniel Boone, and James Harrod, his house was open to all the recent immigrants.  In the early stages of the settlement of the country, his station, like Boone’s and Harrod’s, was one of the main pillars of the colony.  Feeling the importance of this station, as a point of support to the infant settlements, he took effectual measures to keep up an intercourse with the other stations, particularly those of Boone and Harrod.  Dangerous as this intercourse was, Logan generally travelled alone, often by night, and universally with such swiftness of foot, that few could be found able to keep speed with him.

In the year 1780, he received his commission as Colonel, and was soon after a member of the Virginia legislature at Richmond.  In the year 1781, the Indians attacked Montgomery’s station, consisting of six families, connected by blood with Colonel Logan.  The father and brother of Mrs. Logan were killed, and her sister-in-law, with four children, taken prisoners.  This disaster occurred about ten miles from Logan’s fort.  His first object was to rescue the prisoners, and his next to chastise the barbarity of the Indians.  He immediately collected a party of his friends, and repaired to the scene of action.  He was here joined by the bereaved relatives of Montgomery’s family.  He commanded a rapid pursuit of the enemy, who were soon overtaken, and briskly attacked.  They faced upon their assailants, but were beaten after a severe conflict.  William Montgomery killed three Indians, and wounded a fourth.  Two women and three children were rescued.  The savages murdered the other child to prevent its being re-taken.  The other prisoners would have experienced the same fate, had they not fled for their lives into the thickets.
