Looking thru a genealogy file sent by my second cousin, I saw that her ex-husband's uncle Herbert was born in Germany in 1921 and died at Castiglion, Italy, in 1944. (My cousin's mother-in-law had married her father-in-law when he was in the service in West Germany).
I punch his name birth- and death-dates into the German war grave search site at
http://www.volksbund.de/graebersuche/content_suche.asp and get:
Zum Gedenken [In Memory Of]

Vorname: Herbert
Dienstgrad: Obergefreiter [senior Private]
Geburtsdatum: 01.12.1921
Geburtsort:
Todes-/Vermisstendatum [died]: 27.05.1944
Todesort:
Herbert Lenz ruht auf der Kriegsgräberstätte in [rests at the military cemetary in] Pomezia (Italien) .
Endgrablage: Block A Grab 43
Pomezia is one of the main German cemetaries in Italy, midway between Rome and Anzio.
Castiglion is on a main road and rail route well north of the front lines on the date in question. I suspected that Herbert's death was either an accident or as a result of hostile air action. Sure enough, a search of the online US Army Air Force operations diary shows that the 12th (Tactical) Air Force was at this time plastering supply lines with medium and light bombers and jabos in support of the breakout from the Anzio beachhead. The bridge at Castiglion Fiorentino was listed twice as being hit, and toward the end of this period targets are said to become scarce.
Thru my cousin's ex I received this copy of the official notification letter received by Herbert's father:

It lists his cause of death as a bomb fragment to the head from an air attack, and his place of initial burial as Arezzo, about 10 km. or less north of Castiglione. I must assume that German gravesites were consolidated into larger sites like Pomezia after the war. The letter states that he gave his young life according to his oath of allegiance, for the betterment of his people, and ends with the obligatory salute to the madman. :/
I wonder if any of our German speakers can tell from this letter if Herbert was serving in a road/rail transport unit, or in flak or some other capacity? In any case, I offer this as a very small piece of history. Rest in Peace, cousin Herbert.
