What on earth are you smoking, Partisan? The multi-volume set entitled "The War of the Rebellion" is the OFFICIAL UNITED STATES GOVERNMENT PUBLISHED SET OF MILITARY RECORDS DURING THE CIVIL WAR. You cannot get any more "official" or any more "union" than that. It was put out by the government printing office to archive the major military documents. The cornell website has most of the volumes online, including the one I linked you to. That record I cited you is a yankee commander's reports of action to his superior officers during the middle of the war - an official military document from a first hand source appearing in an official government publication.
I have on several occasions said that early on a few black slaves did accompany their masters to battle. Again, cite me a reference in any U.S. Army account.
I just did, Partisan, and you responded by claiming that the official military account in the official records publication of the US Government was not credible since it was titled "The War of the Rebellion"!!! If the official records of the US government don't count on the grounds that YOU do not like their title, I ask you - what else does count? Apparently nothing.
