Now under command of Lieutenant General Mark Wayne Clark, the youngest three-star general in the U.S. Army, and his U.S. Fifth Army, the 167th Brigade, with most of 56th Division (minus the 168th Brigade, temporarily replaced by 201st Guards Brigade), landed at Salerno on 9 September 1943, D-Day, where they were involved in tough fighting almost from the landing, with the 8th Royal Fusiliers in particular being battered by German Tiger tanks. Throughout the fighting the brigade, supported by A Squadron of the Royal Scots Greys, had suffered heavy casualties (roughly 360 per battalion) and, after being relieved by other units, secured the Salerno beachhead and later advanced up the spine of Italy, crossing the Volturno Line and later fought at Monte Camino and crossed the Garigliano river in January 1944. With the rest of the Allied Armies in Italy (AAI), however, the brigade, by now very tired and below strength, was held up by the formidable German defences known as the Gustav Line (also the Winter Line).
