ALLIED HEADQUARTERS, Algiers -- Thousands of American and Allied troops striking their greatest blow to throw the Germans out of Italy landed far behind the enemy lines today and swarmed inland from a miles-long beachhead in a surprise invasion which may decide the fate of Rome.
The German radio said the Allied amphibious force splashed ashore 28 miles from Rome in the area of the Tiber and occupied the port of Nettuno, 32 miles from the capital. But early reports here did not specify the landing place.
Gen. Harold R.L.G. Alexander, supreme commander of the new Allied central Mediterranean force, in his first report to headquarters flashed tersely:
"Initial landing successful--situation progressing satisfactorily."
Big Threat To Rome
