Although most writers state that holding the Kuban was a bad idea, was it really?
The Germans held the area with little armor, some infantry, Romanian infantry usable in such terrain, but withdrew a number of good divisions anyway.
Holding the area means the Soviets can't move naval units into the Sea of Azov.
The Germans achieved like a 4-1 attrition ratio on defence.
It was good defensive terrain. (marshes)
