Karen Lips I'm flying threw the thread with apologies to all if I'm repeating previously posted info. You relations unit, the 42nd Miss was involved in a famous action the first day at Gburg at the Railroad Cut. The 42nd was on the extreme right of the line meaning some were more able to escape the cut, funneling to the west and out of the cut that was previously felt to be a strong defensive position. Google the Railroad Cut-Gettysburg for more and some good maps.
Others posted this was Davis's brigades first battle. And it was quite a baptisim under fire coming up against the well-regarded 1st Union infantry corps. They were some tough, battle-hardened men, particularly Cutler's brigade and elements of the Iron brigade. Then of course, Pickett's Charge would test their mettle again and just as severely July 3rd.
