his insult was returned by Nelson slapping
Davis (Killed by a Brother Soldier.--Gen. J. B. Fry.) in the face.
But at the time, exactly what had taken place just before the
shooting was shrouded in mystery by a hundred conflicting stories,
the principal and most credited of which was that Davis had demanded
from Nelson an apology for language used in the original altercation,
and that Nelson's refusal was accompanied by a slap in the face, at
the same moment denouncing Davis as a coward. However this may be,
Nelson, after slapping Davis, moved toward the corridor, from which a
stairway led to the second floor, and just as he was about to ascend,
Davis fired with a pistol that he had obtained from some one near by
after the blow had been struck. The ball entered Nelson's breast
just above the heart, but his great strength enabled him to ascend
the stairway notwithstanding the mortal character of the wound, and
he did not fall till he reached the corridor on the second floor. He
died about half an hour later. The tragedy cast a deep gloom over
all who knew the men, for they both had many warm personal friends;
and affairs at Louisville had hardly recovered as yet from the
confused and discouraging condition which preceded the arrival of
General Buell's army. General Buell reported the killing of Nelson
to the authorities at Washington, and recommended the trial of Davis
by court-martial, but no proceedings were ever instituted against him
in either a civil or military court, so to this day it has not been
determined judicially who was the aggressor. Some months later Davis
was assigned to the command of a division in Buell's army after that
officer had been relieved from its command.

Two Confederate armies, under General Kirby Smith and General Braxton
Bragg, had penetrated into Kentucky, the one under Smith by the way
of Cumberland Gap, the other and main army under Bragg by way of the
Sequatche Valley, Glasgow, and Mumfordsville. Glasgow was captured
by the enemy on the 17th of September, and as the expectation was
that Buell would reach the place in time to save the town, its loss
created considerable alarm in the North, for fears were now
entertained that Bragg would strike Louisville and capture the city
before Buell could arrive on the ground. It became necessary
therefore to put Louisville in a state of defense, and after the
cordon of principal works had been indicated, my troops threw up in
one night a h
