* Ploieşti is the county seat of Prahova County and lies in the historical region of Wallachia in Romania. Although badly damaged after the November 1940 earthquake, the city was a significant source of oil for Nazi Germany. A target of the Oil Campaign of World War II (1941-1944), Ploieşti was attacked repeatedly, such as during the HALPRO raid, and Operation Tidal Wave. -- Wikipedia.
