The rest of the War
In his after-battle report on Fredericksburg on December 18, 1862, Gen. William H. French (commanding Division) said:
I call to the special notice of the general commanding the gallant conduct of Col. H. I. Zinn, One hundred and thirtieth Pennsylvania Volunteers. This officer, conspicuous for his valor at Antietam, was killed while carrying the colors of his regiment to the front, after the standard-bearer had fallen.1
