The 5th Division saw action during the invasion of Sicily where, towards the end of the campaign, in early August, the divisional commander, Major-General Berney-Ficklin, who had commanded the division since July 1940, was replaced by Major-General Gerard Bucknall. The division was pulled out of the line and absorbed replacements, and invaded the Italian mainland in Operation Baytown on 3 September (four years since Britain's entry into the war), still as part of XIII Corps of the Eighth Army, but now serving alongside the 1st Canadian Infantry Division, and advanced up the spine of Italy. Later in the year, the division fought in the Moro River Campaign, although sustaining relatively light casualties in comparison to the other Allied formations involved.
