This link has a map of the entire Italian Front at the time of the Spring Offensive on 11 May 1944.
I agree with Rocky about the movie "Anzio".
This 1968 movie stars Robert Mitchum as a war correspondent who joins up with Peter Falk, who plays a corporal in the 1st Special Service Forces. They borrow a jeep and drive to Rome and back without meeting any German forces, but their report on this absence of the enemy is discounted.
Robert Mitchum is a tough guy. If he had REALLY been there in 1944, then I'm sure the Allies could have waltzed into Rome. Ha!
If you read the history books and the Monday-morning Quarterbacks, they say that Lucas could have pushed directly into Rome without any heavy resistance. Maybe. My opinion is that if he had done that, then the battle would have been fought in the streets of Rome and someone would have resorted to shelling or bombing of the Eternal City. I do believe he should have pushed out of the beaches and into the Alban Hills.
The above comments are my personal opinnions and do not reflect the opinions of the management.
