The Cost of Investing in Stalingrad

Why don't the Germans just invest Stalingrad and go round it, asks Jim Boulden. It's because what happens is your objective is Stalingrad quickly, he says. You're committed to this course of action and you've already invested so much,. So the only way you can stop it is by pulling out - but when that doesn't happen, you suddenly get stuck here a little bit. There's no question that they go in there with a certain degree of complacency as their 60 second army hasn't done particularly well on the Eastern Front.
