“No man has ever been more alive to the importance of opportunism in battle. No man has ever been more conscious of time, of the fleeting nature of opportunity, of the rapidity with which the command must act or react. Rommel has an instinctive feeling for where and when a chance of battle would present itself, for where his own dynamic presence would make the different–perhaps a different only measurable in minutes but minutes of inestimable value–between a seized or a lost opportunity.”
