No Bradley put the brakes on. Ike was not the author of that decision. One could argue that was the right decision given the circumstances but Bradley, not Ike, owns the decision.

“There’s a funny story about the capture of Trier that shows the differences between General Patton and General Bradley and their ability to judge a military situation. After the battle was already won and the Third Army had taken the city, General Patton received a message from General Bradley. The message said, “Bypass Trier. It would take too many divisions to capture it.” Patton’s humorous reply to Bradley was, “Have already taken city, do you want me to give it back?””
