The brigade as a formation, was not involved in
Operation Husky, the
Allied invasion of Sicily, but
40 RM Commando was involved in the assault landings as Army Troops. In
Operation Shingle, the assault at
Anzio,
No. 9 (Army) Commando and
No. 43 (Royal Marine) Commando were the only units involved. The whole brigade was involved in the
final offensive of the
Italian Campaign. In 1945 the brigade was involved in the Lake Comacchio battle,
Operation Roast, where
Corporal Thomas Peck Hunter of 43 Commando was posthumously awarded the
Victoria Cross for conspicuous Gallantry in single-handedly clearing a farmstead housing three Spandau machine guns after charging across 200 metres of open ground firing his Bren gun from the hip, then moving to an exposed position to draw fire away from his comrades by engaging further Spandaus entrenched on the far side of the canal. After Operation Roast the brigade was involved in the follow-up actions until the
German surrender. The brigade remained in the area on security duties until it was disbanded in 1946 ==Formation==
