Yep - I have that and it flies against what the 5th Wisconsin Infantry unit history states.

That was one of the sources I cited. And it seems that I misread it. The letter written by the soldier to his father on the 13th mentions the regiments movements on the 4th and then states that the flag was indeed taken on the 5th of May. So how did the unit history get it wrong????
