I too am attempting to get a military record (for August Löloff) from that time period. Follow is a quote from a letter written by his sister in 1920:
"...beloved brother August. He was shot in the head while he was eating lunch, between one and two o'clock, in Orleans, France, December 2, 1870/71. He died instantly.
"....August took part in the seige at Metz and Paris and was also killed in action in the Battle of Orleans on December 2, 1870, shot through the head. According to the Army Chaplain Lossel, August is buried in the graveyard at Loigny. Grenadier Lichtwart, lst Company, 89 Regiment, Grenadier Schroder, Company 89, and a Grenadier from the 90th Regiment whose name I don't recall; and Fusiliers Schlieman, Loloff, and Burmeister from the 9the Company, 90th Regiment are all buried in the second grave next to the wall separating the graveyard from the village road. He was a slender noble looking man with fair hair, athletic body, and a gentle, cheerful disposition."
Ironically, she wrote the letter to her brother George in San Antonio, Texas not knowing he had died in the flu epidemic of 1917. Her 42 page letter describes many of the hardships she endured during WWI including the death of one son.
I received a reply to my request for information. These old records are now unavailable until June 2010 since they are undergoing preservation treatment. If you so desire I will send you a copy of the translation of the reply I received.
I would appreciate any information you may have on the battles mentioned in the letter.
