The 27th Kentucky Infantry Regiment was formed starting about September of 1861 within about 20 miles of General Buckner's rebel forces. They first trained on the battlefield of Shiloh among the blood dried pools of blood after helping to remove the dead.
One can learn more about the exploits of the unit including actions that involved my grand fathers particular unit, Company D. The following exploits were written by Col. Ward the commander of the regiment. A story follows the link. The link is: http://www.unionregimentsofkentucky.com/thomasspeed/infantry/27kyinf.html
In the story Company D was trapped on the wrong side of the Tennessee river being pressed by a regiment of Confederate infantry only to escape under the cover of darkness. As it turned out grandfather was almost captured when he and the group of soldiers he was with thought the soldiers they meet in the night were rescuers, when in point of fact it was Confederates coming to capture them. They escaped amid a fight and later made their way back across the river later that night.
