MEDAL OF HONOR: CHARLES TILDEN
There is a list here, the names seem reasonable given the expected members of Blenker's staff. Quite a collection of officers.
Genl Louis Blenker & Staff ; Photod at Fairfax CH 1 - Captain Vizen ; 2 - Col George Von Armsburg ; 3 Col Lorenzo Cantador ; 4 Possibly Count Von Ingelheim ; 5 Cap Schulz ; 6 Lieut Strang ; 7 Genl Julius Stahl ; 8 Genl Louis Blenker ; 9 Col Finkelmeier ; 10 Lt Col Repetti ; 1 Col Oswald Salm Salm ; 12 Capt Hugo Von Brandenstein ; 13 Capt Gustav Zschüschen ; 14 Hunsdorfer ; 15 Foster ; 16 Col Eugene Count Kozley ; 17 Lt Herman Boker ; 18 Capt Scheuerman ; 19 Shimmel.
Interesting. I know Cantador has the 27th Penn at Gettysburg but I know no more about him. George von Armsburg will be Georg von Amsberg of the 45th NY who finished Gettysburg with a brigade. Stahl and Blenker are well known. Oswald Salm Salm will be Felix zu Salm Salm of 68th New York who finished the war with a brigade under Steedman in Georgia (veteran of many European Wars, and Mexico, before being killed in the Franco-Prussian War. I have a book on him and his American wife). The others I’ll have to look up tomorrow...
"Schimmel" with the big beard could be Alexander Schimmelfennig. He had the 74th PA in Blenker's division so the timing would make sense. Kozlay had the 54th NY.
Kozlay resigns 19 March 1863 through various frustrations over regimental fraud. He gets restored in 1864. No evidence he is a Count or claimed to be either...http://dmna.ny.gov/historic/reghist/civil/infantry/54thInf/54thInfKozlayJournal1.htm
Lt.Col. Alessandro Repetti seems rather interesting. Italian Revolutionary who supported the Roman Republic but was discharged 19 June 1862 not long after the Battle of Cross Keys. https://www.jstor.org/stable/29776913?read-now=1&refreqid=excelsior%3A8192a3e7b2672153a9acd6c081c81133&seq=15#page_scan_tab_contents
