Not so sure it could happen in today’s structured world.
Once he saw the bulge forming, he had his folks create a plan and execute it almost immediately.
You need well trained, supplied, and motivated forces to do that.
I think Patton’s focus on discipline and planning had a ton to do with it. Also, his personal discipline to NOT micro manage his officers. That, above all else, is one of the things about him that I admire.
“In about fifteen minutes, we’re going to start turning these boys into fanatics - razors. They’ll lose their fear of the Germans. I only hope to God they never lose their fear of me.”
Patton’s intelligence people discerned the German build up before the Bulge, and reported it. They were ignored. Eisenhower and Bradley underestimated the enemy. Never a good idea.
