Are you all talking about the skirmish between some of Hobson's Federals and Gen. Adam R. Johnson's men on 3 Jun 1863? Gen. Johnson was with Morgan on his long raid into IN and OH and had to clear the Federal pickets out of the way (near Marrowbone) in order to meet up with Morgan at Burkesville. Here is what Johnson says in his book "The Partisan Rangers of the Confederate States Army" written in 1904:
Captain Helm had returned and reported a large body of cavalry near Marrow Bone creek, with strong pickets on our road. I sent Captain Tipton's company of Cluke's regiment and Captain Bennett of Owen's regiment with Captain Helm's scouts, to attack the Federal pickets and drive them in on the main body. This was handsomely done, and my brigade, in column of fours, moved rapidly on the road, and passed the enemy without molestation; they believed from the spirited attack on their outposts that a general assault was intended, and took position on a heavily-wooded ridge and awaited our attack. A heavy fog covered our movement and we were many miles on our road before they discoved our departure.
from page 143.
Hobson was critized for not coming out in force to meet Johnson. Some feel like he could have ended or severely crippled Morgan's raid at that point.
