The 'Kampf um Rom' was the German overall scheme for the defence of the Nettuno area of Italy in the event that the Allies attempted a direct assault on the west coast of the country at a point close to Rome (1943/44).
The basic elements of the plan were used in assembling the forces required to tackle the Allied 'Shingle' landing at Anzio, and thus constituted the basis of the German defence in the period between 23 January 1943, just after the Allied 'Shingle' landing, and 6 June 1943 when the Allies entered Rome after their 'Buffalo' break-out from the Anzio lodgement.
