Concordance between the Italian campaigns and their treatment in Big Pigeon

The six official US ground campaigns in Italy:

1 - Sicily: 9 July–17 August 1943, the Allied invasion and liberation of the Italian island of Sicily

2 - Naples-Foggia: 9 September 1943–21 January 1944, from the Allied landings on the Italian mainland at Salerno to the arrival at the Gustav Line in the Cassino area

3 - Anzio: 22 January–24 May 1944, the landing and protracted battles at Anzio

4 - Rome–Arno: 22 January–9 September 1944, from the Gustav Line battles near Cassino through Rome to the arrival at the Gothic Line north of the Arno River

5 - Northern Apennines: 10 September 1944–4 April 1945, the Gothic Line battles in or near the northern Apennine Mountains

6 - Po Valley: 5 April–8 May 1945, the 1945 Allied spring offensive into the plains of northern Italy
