Saratov Encirclement (circa 182.983 square kilometers)

[Skywalk]

Took me 5 months to build up the two pincers, the encirclement was so large that the middle area automatically passed under my control the turn after.
The soviets (which are 90% Guards for some reason) had to shorten the line on several occasions, which made the encirclement smaller than what it started off as.
The first picture indicates the starting position and the plan I had made.
The last picture shows what I was talking about at the beginning.
