The Concordia Vega Oil Refinery at Ploesti, Romania, was part of the area's petroleum-producing complex that was crucial to the German war effort. Allied bombers attacked the region repeatedly from 1942 to 1945, destroying (1) distillation plants, (2) boiler houses, and (3) cracking plants. The blasted oil storage tanks in the foreground left the Germans with no place to store whatever petroleum they were able to refine in the damaged operation.
