Shelling of Cona L’Olmo di Paradiso south of Arezzo 7/44

[grassi]

Hi,

I am looking for information about a German artillery barrage against some Allied troops south of Arezzo in July 1944.

1. The Germans bombarded an important crossroad at a place called “Cona L’Olmo di Paradiso” (?) appr. 4 km south of Arezzo (maybe route 73 and route 71? => http://www.nzetc.org/etexts/WH2-2Ita/WH2-2ItaP013a.jpg ).
2. The area was shelled by “Kampfgruppe Prentl” for one and a half hours with 8,8cm guns (3.000 grenades) and by an unknown German artillery regiment (maybe the one of 305. Infanterie-Division or 15. Panzergrenadier-Division?).
3. The event seems to have taken place around July 22nd 1944. The barrage may have caused considerable damage to infantry, tanks, tents and transports.

Which allied troops were affected? Which damaged occurred?

Any help is much appreciated!
