“Tactical successes must be ruthlessly exploited. A routed enemy who, on the day of his flight, can be rounded up without much effort, may reappear on the morrow restored to his full fighting power.” (Rommel, 1953, p.398).
Field-Marshal Erwin Rommel (the Desert Fox), World War I junior officer and World War II General, considered a brilliant military commander; adored by his troops and feared by his enemies.
