After the victory in Tunisia, the brigade did not take part in the Allied invasion of Sicily but instead the whole division rested at Homs and trained in amphibious warfare for the invasion of Italy. The brigade landed in Italy on 16 September 1943 during the early stages of fighting in the Italian theatre with British X Corps, commanded by Lieutenant-General Richard McCreery, temporarily under command of U.S. Fifth Army during the Battle for the Salerno beachhead where the brigade relieved its duplicate 169th (London) Infantry Brigade (consisting of the three 2nd Line duplicate battalions: 2/5th, 2/6th, and 2/7th, formed when the TA was doubled in size in 1939), part of the 56th (London) Infantry Division. The assembly of six battalions of a single regiment in two brigades is believed to be a unique event in the history of the British Army and is now a special Regimental Day, called Salerno Day, in the Princess of Wales's Royal Regiment (the successor regiment to the Queen's).
