Below is a description of the aftermath of Champion Hill, written by a Cpl. in the 16th Ohio. In it he describes a German regiment's sacrifice in that battle. I thought you and others might be interested in the account.
The regiment being described served in the division commanded by Osterhaus:
A new German regiment of ours that fought on the right had been made the target of many a sportive remark by reason of their peculiar national ways. They wore Sibley hats and long dress coats, and the most of them smoked German pipes. They were a new organization, patriotic and well disciplined, but previous to this had not been tested in battle. To the witticisms of their comrades in other regiments they generally replied: "Shust you vait, ve shows you how to fight." And they kept their promise. On that dreaded day, at Champion Hill, the emulated the example of their ancient ancestors of the Teutoburg [sic] forest. The Germans for a time were so situated, by reason of the topography of the country, that they were out of sight of the troops to the right and left. The rebels detecting the peculiar new looking appearance of their uniforms quickly concluded that they were new troops and would be easy to break, attacked them with particular energy. Rolling volleys and clouds of smoke marked the alignment of the Germans until the repeated onsets of the enemy were repulsed with slaughter. Then from hundreds of deep Teuton chests went up a yell that proclaimed them veterans and silenced forever the satire of their neighbors. But the glory had been purchased at a ghastly price. Scores of the faithful regiment lay on the ground dead or wounded. After the battle a long trench was dug and the dead Germans with their dress coats neatly buttoned were laid side by side and buried with the honors of a war.
